Does My Car Battery Need Maintenance?

Other then driving the vehicle on a regular basis to keep the battery fully charged, most batteries require minimal maintenance - provided the battery is holding a charge and functioning normally.

Most manufacturers now make maintenance free batteries with sealed tops. This makes it impossible to check the water level inside the battery unless the battery case is translucent and you can see the water level in the cells. Even then, there are no provisions for adding make-up water if the water level is low.
