Thanks for your video, I just saved my 10 years old NIMH battery! Well done bro!!!

[@billwilliams6338]

what is the conditioning doing to the nickel metal hydride battery you can only condition the battery 2 times only?

[@kvmods]

what is the cutoff voltage of a 9.2v nimh battery? when i measure with my multimeter its 11v. is it 7.2v?

[@theprinceofliberia6793]

Thanks man. I didn't know about military amps per hour changing values

[@YouLikeToast]

Gr8 video. Ty!

[@WigganRC]

Nice informative video 👍🏾

[@travissierra21]

thank you for the very simply explained video. I have a 7.2 V 3800 mA that’s going on nine months old now and when I checked the resistance on my charger resistance came in at over 900. it could mean that the battery has been used so much almost every weekend and sometimes during the week and then probably not charged properly at first, that it could just be wore out. Please shoot me a message back if you wish with your comments on what I’ve just said.

[@djsprc]

Depending how you use your battery and how you charge it. And how you cycle it might determine its life but unfortunately some batteries May not be the same it’s just it’s nature it may last like it may not last might give you different resistance

[@itsmee0073]

Hi have the HITEC x1 ac plys and I am wondering what the term "dry" means while starting a cycle, it says it in the bottom left of the screen.

[@djsprc]

I do apologize I never saw the name dry on the screen.

[@funkiephil2301]

Not exactly a question on this video but what ampage should I discharge at? My charger let’s me manually set it from 0.1A all the way up to 2.0A in 0.1 increments I have 5000amp battery’s NiMH

[@angeldoom4207]

I don’t know if this is correct but I have a 5000 mah 7 cell nimh and I did 5.0 amp charge and .5-1.0 discharge

[@Gpumpfit]

Thanks good explanation

[@CODMWX]

Is it also okay to charge them and then let them sit on the shelf for a week or two charge them again and go run them?

[@djsprc]

That’s correct there’s no problem doing that.

[@mikewade4057]

What about breaking in a new battery by cycling it? And what would be a safe discharge rate of a 5000 mah 6 cell

[@djsprc]

Do I cycle to break in your battery yes you can personally I would do 3 Amp to discharge. Just make sure to let it cool down before charging it or discharge it.

[@RodEvens]

Thank you

[@MattN03]

I just got a Arrma Granite Voltage and it came with a 1800 battery. How do i know how many amps i should charge the battery at?

[@djsprc]

Look at the amp 1800 it 1.8 amp

[@angelsoverme]

How may volts do I discharge battery to on a 9.6 volt battery pack. Is it 1 volt

[@djsprc]

The charger will pretty much discharge it to 0 V

[@hallobyebye699]

I have one question. Got myself a 6volt, 5cell, 4600mAH Nimh battery for my Baja. I kinda messed up with the discharging... (got a IMAX b6 mini as a charger) I hooked it up and ordered my charger to decrease the volts to 4V. with a 1,1 phase. In stead of 1.0 volts..🤦🏾‍♂️🤦🏾‍♂️🤦🏾‍♂️🤦🏾‍♂️🤦🏾‍♂️ When i came back and noticed what happened. I flipped the switch in the on position to let the servos drain the battery and call it a night. The next moring the battery is low.. nothing is working so I started charging it and find out that only 1153mah was pumped into the battery... and has a volt's of 6,43V...... sooooooo. Did I messed up my battery or is there still a change that I can restore it? Sinds it is a new battery. Hope that you can help me out 👏🏾👏🏾👏🏾👏🏾👏🏾

[@djsprc]

Sorry for the late reply for an nimh battery it’s normal for the battery to be more than 6 V when she’s fully charged basically what I’m seeing is the discharge way you use is not correct. What you’re going to need to do on your charger go to nimh mode. Then select cycle you will need to cycle your battery at least once or twice now I cannot guarantee you will be able to get the full capacity back of your battery you might be able to get good part of it back but you should never plug in your battery putting the switch on and leave it on for nothing. Doing a cycle charge on your battery will help you a lot.

[@hallobyebye699]

@@djsprc alright thanks for the advice. I will give a update about how the process

[@hallobyebye699]

Here is the update that I would gif. It was going quite well. The charger crammed 3100( more or less) into the battery and I was glad!! Until.... my cat start paying attention to the cables and sadly to say, I had to order a new battery....

[@djsprc]

Hallo Byebye Sorry to hear that that’s unfortunate for you but at least now you will know your battery is in good shape.

[@zillerwedding1524]

What setting do you use for discharge

[@djsprc]

It depends on you I would suggest two cycles in the amperage the highest one will take less time

[@yamahschector]

My venom nimh batteries get very hot charging with the venom pro duo charger. Then the speed pack battery I charge on the same charger does not get hot at all. I a thinking I am doing something wrong

[@djsprc]

I am not sure what amperage you’re charging at but do not surpass the capacity of the battery if the battery is a 5000 5amp is good enough. It is normal for a nimh battery to come hot when charging

[@richardpatrick2872]

nice video, how does one know when the battery is no longer goodthanks

[@djsprc]

How to find out if your battery still good 1 you will notice you’re getting less running time even if you do a cycle 2 if you notice when you’re charging your battery and using it doesn’t keep us charge 3 if one of your cell becomes hotter than the other ones your batteries gone

[@bunasir394]

Hi my dear I have 9.6 v 5000mah nimh battery its new not use too much but The problem its not come full charge I mean when I put to charge and after hours and half the charger is beeping and its showing full but the milliamp only 2000 or some time 2500 why not 5000 milliamp I charge 1 amp so can I need cycle also the battery is not too hot can you tell me what reason sorry for long question

[@djsprc]

Yes he will need to cycle your battery the reason this is happening is your batteries been sitting for too long not be active he created itself a memory you will need to try to get rid of that memory by doing a cycle or two on it you may not be able to get the full amount again but you should get more than you’re telling me

[@bunasir394]

djsprc thank you my friend so I need cycle after cycle the battery is full amount I will try then I will reply I think one cycle ok or two

[@djsprc]

Bu Nasir You might need to do more than one and two but after a while you’ll see you’ll gain some more time with it

[@MikeOliverDesign]

I have that battery and the 2nd time I charged it it hit 2000 so I unplugged it. Is that ok to let it keep going that far past 1800? Thanks

[@djsprc]

Some nimh batteries Will charge higher than that capacity that’s normal

[@MikeOliverDesign]

@@djsprc Thank you, good to know

[@Veganarchy-Zetetic]

Could anyone please help me with NIMH information as I am just getting contradicting answers all of the time. 1. Do you need to 'condition' a new NIMH battery by slow charging it and discharging it multiple times? 2. Is a slow charge better than a fast charge to ensure longevity of the battery? 3. What is the best charge rate for longevity? 0.1C, .05C, 1C?

[@djsprc]

They do say conditioning your battery it’s supposed to be good personally I never did and yes slow charging your battery will give it more life normal rate to charge usually is the capacity of your battery if you have 3300 nimh charge rate wood be 3 amp for a 5000 nimh I would do 4 amp

[@Veganarchy-Zetetic]

@@djsprc Thank you for the help.

[@CHAOZHOUREN]

How do we decide the appropriate charging current for the battery? I heard about c/10, c/3 and so on...

[@djsprc]

CHAOZHOUREN usually is what's written on your battery. Let say that your battery is a 5000. You could charge it at 5 Amp. But usually what I do anything that's over 2 Amp. I charge at 2 Amp

[@justinjones5281]

djsprc good call if you have the time trickle charges allow the cells to catch up to each other without overheating damaged cells

[@jonathanmackey3282]

It cleared some things up for me on the cycle charge and discharge

[@CODMWX]

Why 2 cycles? why not 1? and is it correct that one cycle means 1 discharge and 1 charge? And is this also good to do every month?

[@djsprc]

Yes you can do only one cycle but you would be more in your advantage to do more then one cycles you should do it when your batteries been sitting for a while not been used.

[@trebor1841978]

@@djsprc How long does it each cycle take? eg I have a 5000mah battery

Hi, my 9,6v nimh brand new battery shows 9, 3 v on my multimeter, but the battery is virtually flat and will barely cycle my ak, what could be the problem? I tested the multi meter with other batteries and its fine? Can you shed any light please?

[@djsprc]

Using a multimeter will not get you a correct reading. The reason why because you don’t have a load on the battery once you put a load I’ll give you a different reading you might have a bad cell in it. When you put it on the charger verify if it’s not a cell hotter than the other ones. If that’s the case then you have a bad cell.

[@ianhinrichsendrummer2113]

@@djsprc Ok, tks so much, no all cells are good, no hot ones.

so when charging a nimh thats 4200 mah i would discaharge and charge oit at 2.0 amps when doing a cycle battery

That correct

[@anthonyaviles8665]

@@djsprc whats the final voltage that the battery charges to this charger charges the batteries to 1.5 vols per cell thats what im trying to find out

[@djsprc]

Anthony Aviles depends on the amount of cell you have calculate the amount of cells Times 1.5 if you have 5 cell x1.5 it a 7.5 volt now once it’s fully charge it’s going to be higher voltage but that’s normal.

[@precipitation9896]

I got only traxxas nimh charger. How can I do this process with it?

Hey, I have an issue with my 5100 mah ni-mh battery. It will not charge. Does that mean it’s dead? I’m confused. (I’m kind of a noob at this stuff and I do not have your charger)

[@djsprc]

Sport Junkie If the battery won’t take a charge at all. possibility that the battery might be done. What charger do you have

[@sportjunkie2833]

djsprc Traxxas ez peak dual

[@djsprc]

Sport Junkie if you ez peak. Won’t charge your battery dad means probably your battery is dead.

[@djsprc]

Sport Junkie depending on the age of your battery if your charger is giving a little bit of current you might be able to save it by discharging it and recharging it discharging recharging it. Got a question did you try another battery on your charger to make sure it’s not the charger

[@sportjunkie2833]

djsprc yes, my 3300 maH works fine.

[@northwind9505]

This good. But all I have is a small wall charger for my radio. How could cycle my batteries? Leave the radio on and airplane till dead and recharge?

[@djsprc]

If it’s your battery in your radio for an airplane I would not try to cycle it because if your battery dies in your radio you’re gonna crash your airplane. If your batt in your remote is a NIMH yes you would need to leave it on until it’s dead and recharge it.

[@northwind9505]

OK. So after every flight run the battery down before the next charge?

[@djsprc]

North wind You do a cycle on your battery when it’s an older battery it’s able to gain some milliamp back if it’s a new battery you don’t need to do it

[@northwind9505]

Thank so much. Yes very new battery. lol

[@jaydenly1382]

Why did it take 77minuties to to discharge my battery 1300 mah? I have a 5000 mah battery and I feel like it's gonna take me a hole day to do 2 cycles

[@djsprc]

The bikesandgame Mix It depends on the discharge rate you choose if you choose like in one amp it will take longer if you do a 2amp it will go faster

[@sergiobernal9126]

My batterie won’t charge any idea thank u

[@djsprc]

Sergio Bernal Depending on the age of your battery it could be that reason or the batteries very very low in voltage and the charger is not able to take over

[@sergiobernal9126]

djsprc is like 4months old I just use It twice

[@djsprc]

Sergio Bernal What you can try to do depending on the charger you have do a slow charge low milliamp and see if the battery takes it

[@sergiobernal9126]

djsprc I got the same charger as the one u have

[@djsprc]

Sergio Bernal It’s always possible that you have bad cells in it trying to lower amperage and see if it comes back if it doesn’t unfortunately it’s a bad battery.

[@marlixtorrealba5701]

There are several tips for doing a pro job Don't attempt to do this until you know what you are doing - the acid can burn your skin check the voltage first - there may be a dead cell which would waste your time. Check the battery fluid. Try to fully charge the battery. (I learned about these and more on Jons Mender Guide website )

[@djsprc]

This method is for a remote control vehicle battery not at lead acid battery for a real car verify your fax before doing a comment

[@shancyroesner9212]

Problem with my battery: Is not giving my car it’s full potential of speed and power Even if I fully charge it and let it cool down it still weak.

[@djsprc]

I if your battery is nimh end it has a few years it might’ve created itself a memory. When that happens it decreases your running time. The other issue might be when you’re charging it if you feel one cell hotter than the other ones or one cell boiling hot that means there is a defect cell or a dead cell and dad will decrease your performance. Reason one if it’s an old battery you might need a new one reason to if when cell gets hotter than the other ones you have a damage battery time to get a new one. Now if it’s a lipo you might have a damage cell and your lipo.

[@Toddothegoddo]

My nimh just melted its cover off

[@djsprc]

Jim might have a bad cell that’s why it’s melted it overheated itself or you charge that to high amperage

djsprc ok so today i ran it then charged it then ran it again and when i took the body off it was showing the bare metal cell is that bad it worked like normal during the run. Could it be puffed or just too hot?
