Car batteries are filled with sulfuric acid, not water. The battery fluids get "topped up" with distilled water if they get low.

If you're talking about a car battery...maybe. If it is a maintenance-free battery than there is usually no way to add water to it. If it is not maintenance-free than it will usually have a way to add water, but the only type of water that should be added is pure, demineralized water.
add water and charge the battery
The energy stored in a car battery, or other cells or batteries, is chemical energy.
If the battery light comes on when you try to start your car, either your battery is low or your alternator is going bad. These can be checked by going to an Advance Auto or Auto Zone, they will test it for you for free.
Most cars have a 12 volt, 6 cell battery.

You will shorten the life of the battery. Only add Distilled water to a battery.
have your alternator check. It is like that for most car. It is not the battery's fault. But you could have a lose connection to your battery.
