How to prepare a new motorcycle battery with acid.

How to fill a wet lead acid motorcycle battery with the acid / water for battery usage. This is great info for anyone with a non sealed motorcycle, atv, or lawn equipment battery. Please wear safety glasses when you do this, the sulfuric acid is no joke, and it won't do your eyes any good.

Just bought an old honda cb750 that had one of these types of batteries that was completely dead and dry...I didn't know the history of it so I just decided to get a new one. Had never done the filling thing before and the instructions that it came with were almost useless, so thanks for clearing it up for me....I opted for some rubber gloves along with saftey glasses and glad I did because the fill hose leaked a bit and would've gotte all over my hands! Safety first, people!

[@KnobleMoto]

Glad to hear it helped!!!

[@douglasdelay]

Thank you so much for making this video it will really help me since I need to purchase a new battery. You da man!

[@KnobleMoto]

You are welcome. I am glad it helped.

[@Slowdownmoveover-eb5ot]

great video i prefer the other type battery where you just plop the acid pack on top but unfortunately it wasnt available so i got this one. Thx for the video this really helped out because the directions it comes with are confusing

[@KnobleMoto]

You’re welcome. I prefer the individual packs too. It’s so much easier

[@Slowdownmoveover-eb5ot]

@@KnobleMoto definitely easier lol

[@therabbitcity]

Very useful video Thank you! Now to drink the extra battery acid

[@KnobleMoto]

😂😂😂😂 new TikTok challenge?

[@bucurvlad5571]

A very useful video. The first one I've seen with the "one at a time fill" method. Thank you so much!

[@bucurvlad5571]

But you should let the liquid "rest" after you pour it, depending on the producer's recommandation (30 min - 1 hour), because if not, the gas is going to get trapped and the battery is going to expand and might damage the battery.

[@KnobleMoto]

@@bucurvlad5571 that’s a good call. I think I mentioned having to top it off. But I would have to watch it again to be sure. I am glad you enjoyed the video.

[@veronicae.5777]

Thank you so much!!

[@KnobleMoto]

You’re welcome

[@Mdismail-nz1fu]

Thank you 👍

[@KnobleMoto]

You’re welcome

[@ELIRAXPRT]

Directions on mine said to fill the battery through the overflow but now the three chambers aren’t level. I’m going to pull the plugs and fill like you did to top off

[@KnobleMoto]

I am shocked you got that much through the overflow! Whoever wrote those instructions was an idiot.

[@lewistaylor1965]

I've never had a battery I could bloody see through as well as this vid...I 've tried shinning a torch behind them and can just about make out the level...I usually end up gauging it through the hole in the top...I've just filled up a new battery and overfilled it...Dang!

[@whylee1377]

I did the same fucking thing too. Turns out low light with a flashlight shining to the ground next to it is how I seen in there. Now that they are all uneven and I put it on charge before I figured the light issue, can I use an eyedropper and even them out after it's charged or while it's charging? That's what I'd like to know. Our host is not the guy to answer that question unfortunately. Update: while it was charging I used the eyedropper to extract from over filled cells to underfilled. Kept it charging. That was at about 3 hour mark and charging finished at 5 hours. Will be couple days yet before I can put it in my sled and try it out. Between now and the I will put it on trickle one more time. Probably tomorrow, will post an update once installed.

[@KnobleMoto]

That works. You just need to make sure the lead plates are submerged.

[@Warhammer778]

Hey brother, i added the acid to my battery today all to the upper level as instructed in the manual but after charging it for 2 hours the level increased.. should i be worried?

[@KnobleMoto]

As long as it didn’t overflow i wouldn’t worry about it.

[@douglasdelay]

My current battery that I bought last year sat on a trickle charger all winter and the charger shows green as good. But when I installed the battery there was no charge. Can these batteries lose acid in them rendering them dead? If so, can I just add the acid to it to make it work again?

[@KnobleMoto]

Sorta. You can add acid, or even distilled water and it should work. But sometimes the lead plates corrode over, and then it won’t work. You can add epson salt to the water you add, and that should clean the corrosion. I have a video that shows how to do it.

[@douglasdelay]

@KnobleMoto Great thanks for your reply I'll check out the video

[@adam-pe2ve]

does anybody know with what should i replace the cap of the battery? because i lost one driving

[@KnobleMoto]

Call a local industrial battery supplier. They will probably give you one.

[@tonynguyen9457]

I filled mine yesterday and for some reason put the vent cap back on. Today I was gonna put the trickle charger on it and noticed the sides are starting to bulge. I’m afraid of what will happen if I take the vent cap back off but now I’m worried it’s gonna explode

[@KnobleMoto]

I would take the vent cap off.

[@tonynguyen9457]

@@KnobleMoto thank you, I did. Never really dealt with filling batteries before and the warnings of explosions etc had me worried. Thanks for responding

[@KnobleMoto]

@@tonynguyen9457 you’re welcome

[@raulmacinca5517]

I don't have a charger. Can i just push the bike to start and ride it to charge?

[@KnobleMoto]

Yes. It will probably have enough power to start the bike. Just make sure you ride it for 20 minutes to get a good charge in there.

[@4ktur]

12v 9h wet battary charging higest watt/ampeer?

[@KnobleMoto]

Don’t charge it with more than two amps. 1 or less is preferred.

[@carlwilliams8279]

How long will it take to charge after putting it in a charger

[@KnobleMoto]

It’s should be ready in 3-4 hours. I often just leave them overnight.

[@jime6385]

So what should you do with the extra sulphuric acid that you have?

[@KnobleMoto]

Ehhhhhh (Shrug) www.atsdr.cdc.gov/toxprofiles/tp117-c4.pdf

[@TCobb47]

Add baking soda water mixture to it. It neutralizes the acid so you can safely discard it.

[@KnobleMoto]

@@TCobb47 that is an excellent idea. Thanks

[@nicolasgrim6253]

Drink it

[@KnobleMoto]

@@nicolasgrim6253 😂😂😂😂

[@diagopaulravina7906]

What about distilled water??

[@KnobleMoto]

You can use distilled water to top it off. But you really should use the acid for the majority of the battery

[@jasonlombardi472]

I had the same question

[@ercost60]

Rubber gloves advised!

[@KnobleMoto]

That takes the excitement out of it

[@kyle0116]

What if I over filled one of the slots???? SOS

[@KnobleMoto]

Nothing really. At worst a little will burb out the overflow. So make sure you have that hose hooked up.

[@kyle0116]

Okay sounds good! I do have it hooked up and my bike is running again, thank you

[@KnobleMoto]

@@kyle0116 you’re welcome. I’m glad I could help.

[@MrJimcasey1]

Take time and get the kink out of the hose first. Don't fuss with it when it's full of acid. Yeah, "...a whiff or two" of the acid won't hurt you. It's the third one that can put some people in the hospital. Who doesn't have covid masks leftover? Who doesn't have some kind of gloves. It's your skin. Who doesn't have some kind of eye glasses around the house. "Acid is no Joke" -like the man says.

[@KnobleMoto]

Skin generally grows back 🤷‍♂️😂

[@emp5352]

Uh. Yeah - you should be wearing gloves and a water-repelling long sleeve when handling acids. You should also have some lye (not soap - lye; like sodium hydroxide) or baking soda saturated in water readily available in case you spill. Never wash strong acids down a normal drain. It will eat your pipes. Always have a wash bowl ready if you get it on clothing or skin. Have a 1L squeeze bottle ready full of distilled water so that you can spray a stream directly into your eye if you get it there. A sink is not going to help you if you can't find your way to it. You need a flow of water readily available. Use a garden hose if need be. If you're washing your eye, only have the acid contaminated eye opened so you don't accidentally transfer it to the other eye. If you have both eyes contaminated, obviously you open both eyes. If you get acid on clothing, take it off immediately. Don't try to neutralize it while you're wearing the damn clothing - you'll get severe burns. It should go without saying - wear something you can take off without having to pull it over your head, so you don't get acid on your face if you spill on your clothes. Those button-up lab coats serve a very functional purpose. Also should be super obvious - this comment is intended for anyone who wants to attempt this at home and hasn't done it yet - not the guy in the video who already did this and has no use for this safety announcement.

[@KnobleMoto]

Poor safety procedures make for great stories though.

[@pankajk8448]

you forgot to wear gloves, acid will burn hands if spilled.

[@KnobleMoto]

What kind of gloves do you wear?

[@KnobleMoto]

@@st-qd8wg you should probably listen to the video with the sound on.
