battery fluid

Distilled water only in a battery
 
never top up a battery with acid after it has been in service, just distilled water, not tap water.
 
Distilled or deionized are both good. Distilled is available in most pharmacies so it might be more convenient.
 
I have been topping up battery's with tap water for close to 40 years with no ill effects.
Distilled water is the best to use, but a top up with plain old water will cause no problems
 
You shouldn't add tap water to your battery because minerals dissolved in the water can cause a deposit to form on the plates causing a reduction in efficiency.

Distilled or deionised water is best. If you can't get this, chip the frost off the inside of your freezer, this is essentially distilled water but make sure it doesn't have any bits of food stuck to it.

Really? Seems like a lot of trouble to go through - especially if one has a freezer made in the last 20 years. i.e. frostless.

Perhaps you could go to the Air Canada Centre and ask for the shavings out of the Zamboni. :D

Why not?
I tried using an 80% acid on an old battery and it did give it some life :shrug:

Aren't they the same?

Edit: nevermind, I googled it. Learn something new today

You are decreasing the effectiveness of the battery. Most of the sulfuric acid would react with the carbonates and other ions in the water
 
When worked for Ontario Hydro they tested Toronto tap water to see it was okay in a battery.(actually we were using cells each about the size of a 5 gallon gas can).
Findings said it would take 7 years for the minerals in T.O. tap to affect a battery with normal top ups. Batteries are pretty much done by then anyhoo.....

But we always used demineralised water .

IIRC correctly; battery electrolyte is 36% sulphuric acid and 64% distilled water. This is what they are engineered to use to provide 2.2v from each cell and not degrade the plates.

On a battery the fluid that evaporates from charging (esp. over charging) is the water. Additionally when a battery is discharged the sulphuric acid attaches to the plates in the cell, so on a discharged battery the hygrometer readings from the cell would indicate a low acid level.

If you top up with more electrolyte or sulphuric acid then you are changing the ratio of water to acid.
 
I have a huge jug of battery acid sitting at work if anyone is interested.
 
Just in case where abouts are you.

Just so you know, sulfuric acid behaves like bleach. Meaning if u get it on your clothes it will leak the colours. Plus try not to get it on your skin.

Just a friendly piece of advice
 
From experience, it'll do a whole lot more than that.

Would 30% do that?

I have some 98% sitting in my garage. If u get it to 80-90% it turns paper and wood into carbon. Totally black
 
Were you one of those kids who experimented with the chemicals found under the kitchen sink? :D

I had a friend who blew his face out with Sodium & water :)

I was making gun powder when I was 13 :D

It was rather unfortunate I couldn't source Glycerin :tongue10:
