For all the cars I owned since 1984, I never add water to the car battery.

Sure, they last 3-5 years and when it dies, just exchange it. The shop will pro-rate it, and I'm good to go for another 3-5 years.

Most batteries you buy, even the ones that said "Maintenance Free," one should still add water.

So the question is, does it really make a difference? When you ask anyone across the board, car batteries will last you about 3-5 years. Sure, there are those who get 7-8 years out of it.

Even if the battery is still ok, it's a good idea to replace them so you don't get stuck somewhere and need a jump.

For guys that DO add water to your batteries, have you noticed any difference?

 

If water level is low, water, [soft water] must be added. 94
