Jeremy; It is quite obvious that you are not only highly intelligent and educated, but your creative mind is what seems to drive you to do what you do. You remind me of my best friend Tom, who passed away a year ago. He too had an incredibly creative and inventive mind, with little or no formal training for some of the fabrications he produced, but rendered some of the most intriguingly sophisticated, yet simple solutions for obstacles that stood before him. Your channel is not only fun and educational, but is also immensely entertaining and practical. I've subscribed to your channel and intend to spend a lot of time gleaning some ideas that you have inspired me to pursue but lacked the inspiration to do so. Thank you for sharing your knowledge with the enthusiasm and candor that sets you apart from all the rest! You're a genius!

[@ExStaticBass]

Whereas small wall-wart power supplies like that are concerned, most of them are current limited switch mode devices. that is to say that they'll put out the maximum amperage and reduce voltage to preserve its internal components. It's not a great idea and if done repeatedly it will damage the adapter. What I would recommend doing is to take jumper cables and connect it to a working battery that is known to be good briefly but long enough to get the charger to start its cycle. This is a quick and easy way to see if there are any problems like self discharge too. Give it a bit of a charge this way and see if it loses any voltage over time. The battery will of course loose a little as the chemistry balances and settles into a charged state. Thus the first measurement of how much charge it has gained should be made around 15 minutes after charging it and then again the next day to see how much has been lost. This is true for lithium 18650 cells too. The cheap Chinese chargers you can get off Ali Express that will charge two cells at a time charge them in parallel. For most intents and purposes this is REALLY BAD especially if you get a cell with an internal short. Fortunately you can tell this relatively quickly as one or both cells will become abnormally hot. Usually though, you can give a couple quick pulses from a known good cell to bring the dead cell's voltage up enough that most smart chargers will take over as if it were any other cell under normal circumstances. As a warning to others, you should never charge lithium batteries in parallel unless they are a reasonably matched set. They explode quite violently and can cause personal harm to you and damage to your property. Lithium fires are no joke. Please be safe rather than sorry...

[@9crutnacker985]

Just a foot note - DON'T try & put out lithium fires with water. The lithium reacts with water producing even more heat so you'll only make the fire more violent. Use C02 or powder extinguishers.

[@JeffKnoxAZ]

A lot of veterans groups collect these and try to refurbish them. Goodwill also sees quite a few of them. If they can't get them going, they will discard them. Guys looking for these sorts of cool parts could find a great resource there - and might find a great way to put their talents and skills to work to help out a deserving vet.

[@Jeremy_Fielding]

I edited the part where I describe its original condition more, but I don't think it was fixable without major cost. At first I thought I might clean it and sell it. But no way. Most of what made it a great wheel chair was literally disabled. As you saw... really only one motor was working, and the actuator for tilt was working. Everything else was corroded over. The damaged motor was completely rusted out on the inside.

[@perrywoodman7544]

A collection of parts may make a good video, or even a vocational seminar for the disabled on repairs to such. Keep the wheels turning for the fight right?

Jeremy, I just want you to know that you and I are a lot alike. I broke down an old wheelchair a few years ago and made a kite retriever out of it with one of the motors and the controller. Then I took the second motor and made a crab pot puller for my boat. In the last 5 days I have picked up and stripped down two treadmills. One will be used for an edge sander I am building and the other will be for a 2x72 belt grinder I will also be building. I've been thinking about making a go cart out of a wheel chair for a long time now but don't know if I'll ever get around to it. I do know the joy you get from doing this stuff, I love it too! Thanks for all your videos, I have really enjoyed watching them and you do a great job telling your story. Take care and be safe.

[@dgm6277]

The chargers have a chip that prevents them from charging when the combined voltage is less than 18vdc. They also will automatically shut down when the batteries are fully charged and they will ten go into maintenance mode. Charging time is 8-12 hours, designed for overnight charging. If the charger shuts off quickly, say within an hour or two probably means the batteries have one or more dead cells. Also when we attempt to revive a low set of batteries we use an automotive battery charger for about four to six hours per battery.

[@Chardt013]

I used to work on these chairs, reconditioning them for the nhs. Check the batteries as they are usually gel and dont mix well with a standard car battery charger. You can tell those batteries are knackered as the sides are sunk in. When the knackered batteries are charging they swell and get hot, obviously when they cool they retract and sink in slightly.

[@Jeremy_Fielding]

+Richard Black yes... they are gel but I use the charger that came with them.

[@MattOGormanSmith]

I open "sealed" gel batteries and top them up with water anyway. sometimes they come back to life (1 or 2 for 3 so far). I had one that wouldn't take more than 50mA but I left it charging on a bench psu for weeks, and it eventually started taking a full charge. Having said all that, high amp Li-ion are getting affordable.

[@jerryguerra348]

Jeremy, thank you for the great videos. Sense you are so kind to share with us, I will share with you. If you are interested in saving the battery's and saving some money, you can. Even if the battery's have a small charge 1 or 2 volts, you may be able to save them. By refurbishing them. Yes even a deep cell gel or a AGM battery can be refurbished. 1.Remove the fill caps on the top of the battery. Drain the battery's acid out into a catch pan. Use a plastic basin as a catch pan. Metal pans will be corroded by the acid. And fail. 2. Mix 10 oz baking soda in 2 leters of warm water. Warm water works best to loosen the gunk in the battery. Poor the baking soda water into the battery cells. 3. Replace the battery caps. Shake the battery, or role it so the baking soda water will get into all the corners and crevices. Place battery in a location out of the way and remove the caps. 4. Lit battery sit for an hour. Drain battery after 1 hour. 5. Fill battery with distilled water to clean out all the baking soda water. Replace caps and shake or role battery again so to clean the battery inside. Empty out water. Repeat cleaning process until no gunk is in battery. 6. Fill battery to proper level with 2 leters distilled water mixed with 10 oz Epsom Salts. Proper level is sometimes marked on the outside. If not, fill to just below the slit on the inside of the fill hole throat. Or just below the bottom of the fill hole throat. A 1/4 inch gap is good. 7. Charge battery on a slow trickel charge for 24 hours. With caps off. After the 24 hour charge, chech for voltage level of 12.6 to 13.5 volts DC. 8. If battery did not charge to 12.6 volts or more, than load drain battery below 6 volts and recharge for 24 hours on a trickle charge. And recheck batter voltage level after the 24 hours. Replace caps after charging. FOR SAFETY: Use rubber or neoprene gloves, eye protection, and an apron of some sort to gard against any acid splashing while working with battery acid. Dry cell battery's will have a silica (sand) in them. It is reusable. Just separate it from the battery acid with a coffee filter or an old rag. Than allow it to dry, and reinstall it back into the battery. AGM battery's have a fiberglass in them. It should not come out. But if it does, use the same procedure as the dry cell silica battery, to recover the fiberglass. Reinstall as needed.

[@windsorrocks]

Just an FYI - many/most of these electric wheelchairs have electromagnetic brakes on the end of the motor - the brake is released when power is applied to the brake - and the brake can be either 12v or 24v coil. The brake must either be removed or powered before you attempt to run the motor. The gearbox may also have a "freewheel" lever, which basically disengages the gearbox from the motor. Tip : old automotive 12v battery chargers have no "low voltage" cutoff, so they'll attempt to charge any battery. Most electric wheelchair motors rotate at between 3000 rpm and 4500 rpm... 350w continuous to 1100w peak... gearboxs around 150rpm to 220rpm. These are actually fairly durable motors, high torque, fairly low speed and cheap/easy to control. Applications are endless. Great video!

[@fx1c333]

The wheelchair motors have an electical brake system on the motors where your lever goes and must have power to release it. In wheelchair mode take the electrical brake off the motor and you can use it for anything you want like your shredder. The torque off the wheelchair can tow a car although slowly as I've told my daughter off many times. A friend has one in his van to pull motorcycles into the van that's on a sled type holder for the bikes in shipping.

By putting the wall wart on the battery first - if the battery was shorted it would show up real quick but the wall wart will not supply enough power to actually explode. IE - reasonably safe. I do it all the time with sealed lead acid batteries. Be sure to check the fluid level before trying. Add distilled water if necessary. Good video - thanks for posting.

[@tomwyrick2824]

I almost scored one of these myself but didn't have the time/space to store and tear it down. What a nice pile of goodies Jeremy! Also the solid and dash lines indicates pulsed DC which is what most home electronics run on since true DC is a little more costly from a manufacturing standpoint. Your charging trick will work for a while but the wall wart usually has a thermal device or a diode or something like that that will pop once the load gets to high or the charger pushes back to much nothing dramatic but the wall wart will be toast. You could check the batteries periodically and remove the wall wart once the voltage starts coming up.

[@Jeremy_Fielding]

Yes... there is a note on the screen in the video that says unplug or disconnect it after about 15 seconds... that is all it takes to get the charger to do its job. I just pulled the wire out after a few seconds when I was doing it the first time.

[@Inspironator]

Hi Jeremy, You didn't just get an electric wheelchair, but instead, the Deluxe! That larger charger is one like mine. I got it cheap at a flea market. I removed the plug, put 2 battery clips on and after reverse engineering the circuit, I modified it to charge 12v batteries and added a volt meter to the front panel. Sweet charger with an unusual circuit that uses SCRs to control the output voltage. As for the smart charger cheat you used, that's the way to get it to work. No danger as long as you unplug the wall wart as soon as the so called smart charger starts. A smaller wall wart probably wouldn't work - too weak.

Thanks for the tour of an electric wheelchair. I suggest you use protection for your hands, such as latex gloves, to prevent the crud from causing problems. I see no problems using a trickle charger as you did on gel cells.

[@Jeremy_Fielding]

[@Elfnetdesigns]

I have one of these that is literally brand new, batteries were flat though and un chargeable. And I have 3 mobility scooters, 2 for parts one working. All this belonged to my mom who passed away a couple years ago. All the motors and controls work on the wheelchair and the one scooter and the scooter even has LED lights and a motorized seat height system. The wheelchair was priced at $11K new I found the paperwork on it. The batteries you have you should have kept the little wall wart on them for a couple hours to trickle charge them before hitting them with the main charger.. Also for wall warts, the striped lead typically means "center" of the barrel connector. With that said the striped lead is usually positive, however in audio related equipment the center connector or striped lead is negative. Not all wall warts have a striped lead either some have a ridged lead (heavier power supplies) and the ridged lead the same rules apply as if it were stripes. In AC the ridged or striped lead is neutral (white) and runs to the wider spade of a US AC plug.

[@Jeremy_Fielding]

When I researched this model it was priced around $6k. As to the wall adapters. That is interesting. I don't remember where I got the one I was using, but it was as described in the video along with some others I have.But, I do have another I used within a day of making the video that was the other way around (stripped positive), so there seems to be some variation in the meaning as you described above. I will investigate this some more so next time I can convey this information more precisely and correctly.

[@Pyrichia]

While I was very poor, I had to get a trickle charger to work on a car with a dead battery I couldn't afford to replace. My solution was similar, but it was to put a AA in series (to get the voltage up juuuust high enough to make the trickle charger work) and then when it had started up, I quickly pulled the AA out of the circuit and connected the car battery. The slight charge boost got the battery over the threshold and it charged from there. The AA was burning hot after just a few seconds of this, and definitely destroyed, but it got me to work the next day.

[@dwp1970]

In talking with a former co-worker who relied on a powered wheelchair the amount of abuse the chair needs to take is massive. Since he still had some mobility his chair took a great deal of strain due to him putting all his weight onto some small areas to gain leverage to move. The community to repair and improve the chairs is small but depended on greatly and the turn around time is never fast enough. If anyone thinks they have improvements this is an area that is always looking for them. One of the fields of work that the humanitarian and karma rewards could be as great as the financial ones. Just a thought if someone is looking for a new line of work or wants to start up a business.

[@markweintraut7912]

Hi Jeremy, you Rock Dude! Your Engineering/Machinist skills are nothing short of amazing! Cool graphics too! Your asking if tricking the charger is ok reminded me of the time I exploded a 6 V tractor battery many years ago. I was in a hurry on the farm one morning, to be ready to bale hay later that day I needed to be sure the tractor battery was up. The old Case 500 used a + ground, and you can figure out the rest of the story. I still thank the Lord I was moving quick that day, I only made it to the barn door 10 or 15 feet away when BOOOOM!!! I turned around just in time to see the top of the battery bouncing in the trusses some 18 feet up. My face was over the top of that battery just 15 seconds earlier! So watch your polarity! I also have a background in electronics, your trick should be fine, I would probably favor an old fashioned charger to get them back to life, then finish with the auto charger. I've used a good car batt with a dead one to trick the stupid/smart charger when it was all i could find one day. You may already know, If you need to parallel 2 or more transformers,they will act as though they have a polarity, get them wrong and the sine wave will be 180 deg. out of phase, but don't worry, they will let you know right away! lol I would rather see you charge you batteries outside your shop, at least the big ones, and especially car batts, they can off gas Hydrogen Sulfide. Oh i just saw a vid on converting a uWave xFormer to a power Xformer with a voltage of your choosing. i.e. old fashioned batt charger! Just need 2 or 4 diodes and a cap. How much current can you get from you variable bench supply, there is your batt charger! I'm happy to see i'm not the only one who dismantles old machines as a past time! : ) Regards, Mark

[@danielmeecham464]

Hi Jeremy, Jackpot with the chair! I constantly do what you've been doing with regard to picking up many different things that people cast aside to the road and take them apart and make use of their parts doing something else. A very important point to mention here is about batteries. Check the fluid level (electrolyte) in the battery cells. Use only distilled water to top them up. Charging electrolyte causes a caustic and volatile vapour in the cell chambers, so it's better to only trickle-charge, but in a well ventilated space! I don't know how many videos you've made, but I'll be watching every one of them! Great job, keeping going! Best regards,

[@superdau]

If a lead acid battery has gotten that low it's usually "dead" (as many people who forgot to take their battery out of their motor bike or scooter over the winter might be able to tell you ;) ). It may take some charge but won't be able to supply a lot of current.

[@P_RO_]

Those can often still be used in low-current applications to good effect. I keep a few "dead" car batteries float-charged to run my radio gear when the power goes out and get about 18 hours from them. These might barely start a car once each so they're not totally dead, just no longer capable of large current draws.

I just discovered your channel. I can't stop watching your videos. Your very talented. Thank you for sharing.

[@Jeremy_Fielding]

Thank you! Welcome to the neighborhood

[@ThePwcj]

I am sooo glad you were there at the right time! This may lead to awesomeness! Thank you and take care. Paul.

[@Blue-zx7ot]

Now new problem where to put all the scrap from curb shopping....great video my friend you have continued to amaze me with your abilities and ideas...tinker on your a gifted man... best wishes

[@P_RO_]

Unless there's a local ordinance against it, in most places there's at least one guy who picks up metal scrap for recycling sales, so just put it by the curb with a "free" sign on it and the disposal problem is solved. If you get lots of larger stuff, the next time you see a guy with a truck full of scrap metal ask them for their phone number. Now you don't even have to move it- they will load whatever you've got themselves.

[@alfredneumann4692]

So some Motors have a collector. And you are also a collector. A motor collector grin cheerio from Germany

Alfred E. Neumann? Sorry, dating myself. Old mad magazine character.

[@alfredneumann4692]

Raleigh, yes, you are right. I was a fan of this magazin. :-)

[@emilee172]

a trick I found with GEL cells is to just put them on a DC power supply with a volt or 2 over the rated voltage and just wait, I found this out because I had tried to charge a very dead cell and after a day nothing happened, i then tried the next cell and same thing except I forgot all about the battery on charge and after a week I see the current draw up to around 399mA and so I let it go and sure enough it came back to about 90% of rated power and then I went ahead and copied that for all cells and they ALL came back

[@user-fb6yd2zc8l]

I have the same chair and I've ditched the heavy/cumbersome lead acid batteries + charger and gave it the Kobalt (Lowes') 24V battery pack.

[@drason69]

Cool video Jeremy. I almost felt like I was watching 'how it's made' in reverse, while you were stripping it down. Lol. Thanks!

[@camgreer]

That chair was a treasure trove of parts 'n stuff. I assume you're stashing all the cool nuts and bolts, etc. Those fasteners are so valuable when you've gotta go down to the hardware store for one or two items. Anyhow, I can't wait to see what cool projects you cook up in that vibrant brain of yours to use these parts.

[@PF-gi9vv]

In the UK (2019), a wheel chair in that condition would be worth over £100, it would be repaired and sold on.

[@ryszarddopierala6624]

Thank you my friend what you doing. Very nice of you.

[@IDoNotLikeHandlesOnYT]

The grease is probably fine. It looks like it has molybdenum disulfide or something similar in it, to make it work better under the pressure between the gear teeth, and that gives it that shiny dark gray appearance.

[@AlexCio]

Great show! I like the effects displaying the single elements! Would be great to get a shot showing the whole scene from time to time and not only a little part! But great show! :)

[@Jeremy_Fielding]

+Alex Cio thank you for the feedback. I didn't think of it but I agree that would add some value to the video. Thanks again

[@nicky31645]

Jeremy , I love your videos. Very informative and if I was your neighbor you would have to get a restraining order to keep me away! I have access to one of those chairs as I volunteer repairing donations for the local Habitat For Humanity Restore. The chair has a bad controller and it costs too much to replace it. I just never came up with a use for the 24V motors and actuator.

[@2steelshells]

Thanks for being a thinker tinkerer! I fall short,but appreciate copy cat ideas off the masters! haha.

[@shadodancer4323]

I must say, on behalf of every handicapped person who can't afford a powered wheel chair , the destruction of this for "parts" hurts

[@rabagochingon]

you are a smart men, good point on fooling the charger... i will try that

[@antresia.9723]

I love your videos.I didn't know a electric wheel chair has dc motors If I see one in the trash I take it.I love DC motors I have a basket tons of Dc motors different sizes,Computer fans,and dvd drive motors also I have a QW-MS305D dc power supply.

[@bohabdestructo7489]

Push drive switch is also a parking break. There's an electromagnet that disengages the break for drive. The lever manually disengages the break. The switch tells the speed controller the break is set or not.

[@Jeremy_Fielding]

Thank you... It wasn't until later that I took it completely apart and realized the "switch" was for the electromagnet break. I just removed the whole break.

[@troutbum61]

Another great video. Thanks. Rather timely of it to pop up in my KZbin suggestions as I just saw a scooter/wheel chair yesterday, for free in the local classifieds. Now I'm thinking I better go get it. Anyhow, another thumbs up and subscriber. Thanks again.

[@Jeremy_Fielding]

That is awesome! And welcome to the neighborhood!

[@CSSIandAssociate]

I got for free myself. They did tell it worked. However, not so sure. Yes, tons of applications for this. I want to make a Six Foot Tall metal gate for our driveway. These motors should easily handle that. Lots of good heavy duty parts.

[@BensChannel-rn7ge]

your the best youtube channel ive been looking for a channel like this

[@Jeremy_Fielding]

Welcome to the neighborhood!

[@robertrosson1990]

Man just a idea,Those gear motors and some of the other parts would be the start of a tank tracked type of Rc vehicle.pretty cool info

[@Jeremy_Fielding]

Interesting idea 💡

[@TheFishingHobby]

Actuators and tilting mechanism have me thinking router lift with tilting table! Can't wait to see what you do with some of your parts from this mobility scooter!

[@Jeremy_Fielding]

+The Fishing Hobby my friend I think you nailed it! Great idea

[@bruceandmarilynzimmerman9883]

Who is this guy!! Excellent. I love it! And he even says he's not an electrician........Geez... :)

[@codycheney3401]

Hey great parts from that ! Its great to se just what makes the tick as well as what parts you can harvest ! Love these videos

[@garyknight8616]

Another great video Jeremy. Always really interesting and also really honest. Thank you.

[@norvillerodgersspeaks]

That DC adapter trick is genius

[@joepuhel2428]

I just picked one up today. first time I've ever seen one on the curb

[@Jeremy_Fielding]

+Joe Puhel same here... that was the first then I got another just a week later! This one still works. I can't find a single thing wrong except the battery was dead. I don't want to salvage it nor do I want to sell it. I am conflicted lol

[@denislostinlondon199]

I have two inexpensive 12 volt car battery chargers. The old one has a transformer, rectifier, meter and not much else. The new fancy electronic charger has a select button and menu of options indicated by LEDs. If a battery has a low voltage (say under 11 volts) the electronic charger will refuse to operate. The solution is to use the basic old charger to boost the voltage of the battery and use the high Tech charger to finish the job. This method works fine until your wife finds that you have two chargers and throws out the old one, "Because you have a new one." Now you know why they have lugs on the chargers to let you screw them to the wall. ;-)

[@ogyaherd9667]

wow, sounds like youre married to my wife ! ! ! "well youve got too much stuff anyhow!"

[@P_RO_]

@@ogyaherd9667 And she's got too many shoes. It's called "making a deal"- she touches and says nothing about my shop and I touch and say nothing about her closet. Put it to her that way and she will agree instantly :)

[@SpatialGuy77]

A year ago - how did I miss this one?! Anyways, too late to tell you not to be so quick to discard those motors - could be as simple as a corroded/broken wire, a bearing and a couple of seals. Those wheelchair motors have gobs of torque!! Another good one - lucky bugger!!

[@wayne1959]

I just scored a similar chair and have 2 good drive units as well as the controller and batteries but I ccant make the toggle control works so I have ordered a couple of DC motor controllers from ebay for $15.00..I want to make a small zero turn cart/buggy for me to get around the farm on..Thanks for the inspiration Jeremy.

[@Jeremy_Fielding]

That sounds like fun... and thank you for the kind words 😀

[@dirk4926]

Lots of great stuff there to mess around with. At first I thought one of those drive motors might work in a Power Wheels build for your kids, but at that low rpm, unless you had the right gearbox, it would probably be slower than and unmodified Power Wheels car. Still, congrats on your sweet score!

[@Jeremy_Fielding]

+Dirk Stabins yeah... we shall see about that lol

[@jlrinc1420]

Actually it depends on how much voltage you use. I power an ebike I built with one and I use 24 volts. It will do around 17 -18 mph on the flats. It gets ridiculously fast at 36 volts. The important question is not how fast will it go but how fast will it stop. Thats your limiting speed with permanent magnet motors,

[@peterfitzwell9658]

I've had a few of those DC power supplies where the wire that has the dashed or solid line was the positive.

[@Jeremy_Fielding]

So have I

[@johnmichaellane1]

I have a manual charger just for batteries like that. The smart chargers are nice but can get in the way at times.
