How to Put Battery Acid in a New Lead-Acid Battery

[@robertvanovereem6974]

Awsome video i been a mechanic 21 yrs now and i highly recommend this video thanks

[@susanmcclyde3933]

I purchased a new battery for my bike today - the parts rep gave me a quick tutorial of how to fill it but this vid was REALLY helpful. Thanks so much!

[@lightningfrog27]

Glad it helped!

[@chickenfighter21]

I'd watch a series where you bought a crate of parts and assembled a motorcycle from scratch. Nice video

[@chrisfrerichs8360]

Well done and straightforward!! Thank you.

[@lightningfrog27]

Glad it was helpful!

I wish I could be sure it isn't obsolete, but I am quite curious about how a lead acid battery would behave if it was charged to full capacity before having it's acid removed. Would it be fully charged if you put the acid back in? How long could it sit before it is only able to come back with a half charge, or if it would ever not be able to regain its full original charge. If it never reaches a state of not being able to regain its full charge again, I'd wager to say a drained car battery would be the best kind of jump starter you could ask for, or should I say indefinite battery replacement. Any idea? Thanks.

Thanks for a simple easy video.

I have a question do you know what would happen if you didn't take that initial seal off the main body of the battery before puncturing the prefilled acid? What happens if those parts of the seal fall into the battery body?

[@lightningfrog27]

Worst case, there would be little pieces of foil tape inside the individual cells. If that happened, those little pieces could potentially be a conductive bridge between lead plates, and provide an internal short circuit within the cell. That could either shorten the life of the battery, or lower the voltage that gets generated. Best case, it falls in there, but doesnt touch anything important, or maybe it just dissolves in the battery acid (depends on what the seal was made of)....and you'd never know that there was an error. ¯\_(ツ)_/¯

Thanks for making this video!

[@EthanCopple]

So for some reason my acid for my new battery all isn’t taking , only one tank is dry, the others are varying levels, they only take if I tap the bottles and that isn’t a defined thing either

[@keepup7981]

so i need a trickle charger to charge the brand new battery? i dont get it. but solid video so thanks

[@lightningfrog27]

Yep! a little counterintuitive...but the charger basically pushes ions off of the anode and onto the cathode. the ion imbalance is what gives us the voltage :)

[@keepup7981]

@@lightningfrog27 gotcha, just ordered a charger 😅 thanks again!

[@Y.Shishani]

After pouring the acid, the battery gets hot, is it ok to leave the battery open for a few hours before fixing the seal?

[@lightningfrog27]

Yeah, it gets warm because of the chemical reaction that creates the battery voltage. Not a big deal at all. Should be fine to leave open so bubbles can escape, just be sure that it's in a safe space where it can't be bumped or spilled!

[@happytrails1963]

So good thanks for video. Replace batteries in 2 bikes and follow these instructions no issues.

[@lightningfrog27]

Great to hear! Glad it helped 😎

[@steeleaquain]

Very helpful thanks

[@rulynsantiago1672]

Asking if the plastic is broken how to fixed,so that leak battery at all

[@rulynsantiago1672]

Top plastic if broken how to closed?

[@lightningfrog27]

That's a really tough question....it needs to be sealed not only for reliable batter function, but also for safety.... battery acid is pretty dangerous! I've seen videos of people using a tool that looks kinda like a soldering iron along with some extra plastic sticks to kinda "weld" cracked plastic shut, but I'm not sure what materials or temperature they used, or even if it worked well afterwards. If I had a broken battery case, I think I'd recommend just replacing it. Good luck!

[@cobra8069]

Does it matter which direction the acid is put in ?

[@lightningfrog27]

Do you mean which order? No, I think it doesn't matter either you do any individual cell before the others as long as you fill all of them within a few minutes of each other.

[@laurabarnes3295]

It hold charge but when it load is on it it will drain in 10 mins

[@lightningfrog27]

Are you talking about an old battery that you are testing, or a new battery that you just put acid in? What kind of load are you putting on it?

[@laurabarnes3295]

@@lightningfrog27 is an old battery and I put distilled water to make it work as normal but the current came up but still drop like hell even with small laod is a dry cell battery 200ah just 3 bulbs each is 10w and it will drain in 1hr

[@lightningfrog27]

@@laurabarnes3295 sounds like there's a problem with those old cells.... probably best to buy a new battery

[@gxnblake3292]

Ummm my drained extremely quick like within a minute or two....

[@lightningfrog27]

Yeah, mine did too. Instructions say to let it take 20 minutes.... probably to let bubbles rise out and/or get any last tiny drops. I bet it would be fine if you didn't wait the full 20 minutes.

[@sharonriffee6097]

Motocycle battery ?

[@lightningfrog27]

Yeah, the battery in the video is for a 2015 CBR300R motorcycle.

[@eodnavigator]

Thanks!

[@lightningfrog27]

You're welcome! Glad it helped :)

[@philliproberts3180]

You didn't indicate what percentage of acid is needed.

[@lightningfrog27]

For the battery I bought, all I had to do was fill the cells with all the acid provided....didn't have to worry about percent full or percent dilution

[@trbokd9382]

You really have to wait a day?

[@lightningfrog27]

Doesn't actually need to be 24 hours....just until it's charged. How long that takes depends on a lot of things (battery capacity, battery chemistry, charger amperage, ambient temperature, etc). Basically just until it's properly/fully charged. I'm busy enough to where I'd rather just come back a day later rather than check on it every few hours 😜.

[@shawnp8429]

This is just stupid, so two days to replace a battery

[@lightningfrog27]

The actual replacement is just minutes...it's the charging that takes time. If you can buy a ready-to-go battery from your local power sports dealer, you can avoid the battery acid hassles.

[@stevethom407]

does not help much as every dry battery i look at had a bottle of acid not one of those fill packs

[@lightningfrog27]

yeah, the fill pack was new to me when i was making this video, but BOY was it easier. When it comes with a jug of acid, you just have to be careful to add the specified amount to each cell. I've found that a pipette (looks like a tiny turkey baster) works great for dialing in the exact amount, since it's really difficult to be accurate with just a funnel. Good luck!
