Is it OK to add reverse osmosis water instead of distilled? I believe RO leaves behind slight amounts of minerals, but distilled might leave behind a few chemicals too, like chlorine. So is it 6/half a dozen? Or is distilled the only way to go? Also, is it possible to revive a dea…

Could you please be more specific about what you mean by the effect of the electrolyte? Contaminants present at levels which may seem to be practically insignificant alone are often not when considered in tandem with other contaminants. Evaluating their significance is possible when the contaminant…

Electrolyte is the water plus sulfuric acid solution. You claim relatively pure water can have a major impact on the battery. How do you know this?

Nice to see the question was still in the same century and all the folks that used to be here. The question is 11 years old though but I think @ok4450 got it right. You don’t change the fluid and really makes little difference what kind of water. But who has a battery anymore that you can add wat…

on the maintenance free batteries you can peel the label up on the top and there are plugs under it. if you pop them out with a pick you can add water and replace plugs. but that will probably void any warranty.

I have duly noted that you don’t value discussing potentially extending the life of a battery.

I’ve never heard of anyone shortening the life of or ruining their battery by using distilled or RO water. Also, these days I’d bet very few batteries get topped off more than once in their lifetime. Perhaps more likely in tropical climates.

People still add water to batteries and they will for another ten years.

The owner of an $85,000 car added water to this battery, over filling it. He then brought the car in with a dead battery, acid leaking and getting onto the paint.
