Damages will occur over time when the engine is running or the battery is connected to a charger.

I checked on-line and sulfuric acid is about $50/gallon, so not really worth changing all the liquid of the battery.

At this point in time, there is very little the OP can do.

I would remove enough acid to expose at least some of the slot to allow venting.
Don't save it, just pour it down the drain. Handle with due caution.

I would also remove some of the fluid in the batteries to bring them to the proper level or they will likely be spewing as they charge. Use a battery hydrometer available at any autosupply place to do this and store the excess in a sealed plastic container to use for your next top up fluid. In that way you will ensure that your acid/water ratio stays in balance-then revert to using distilled water after that.

K I have to jump in

you can use bottled/filtered water..but you will still get some of the minerals that cause build up on your batteries led plates.

Distilled water is not boiled water, it’s the captured steam from boiling water. The minerals stay in the boiling and the steam rises and condenses.
this water is allot easier on your batteries resulting in longer life and less maintenance.

Make your own


Have fun

Hi,

Never add water to acid, always add acid to water.

After removing the electrolyte, before pouring it down a drain add it to a larger amount of water--then neutralize with baking soda. Finally dispose down the drain.

Sorry, but that defies everything I've ever been taught or heard of before. I always add distilled water to the acid in my batteries. I've always heard that you never add any acid to a battery.

Hi Hershey,

I was not speaking of adding distilled water to a battery. I was speaking of diluting the acid to a level where it could be neutralized safely before dumping it down the drain.

If water is added to acid the result is an exothermic reaction and enough heat may be released to cause the acid to boil violently. The stronger the acid the more dangerous it is. That could mean acid flying all over you--and your eyes. If, on the other hand, acid is added to water the acid is almost instantly diluted to the point where it is not a problem.

It is one reason why eye protection and great care should be taken when adding distilled water to a battery jar.

In a chemistry lab is is always safer to dilute an acid by pouring the acid into water. This applies to those working in a kitchen as well. Not the same as adding water to a battery. Battery acid is only about 30% concentrated so it is not super critical.

Although I am not sure it needs to be neutralized. Sulfuric acid is available as a drain cleaner. I used to buy it off the shelf at Home Depot. Do rinse the drain well and no harm in neutralizing either.

Wearing eye protection goes without saying.

A. thank wife for helping.
B. In the future use distilled water.
C. Its done; what TINY damage has occured is done.
D. There is no rational fix; drain the battery and replace the acid; gimmie me a break!
E. It has probably reduced the life of the battery a total of 3 or 4 days, simply replace the battery a week earlier than you had originally planned and you'll have no problems.
