some batteries are marketed as \maintenance - free,\ which means:
○ charging system should never be tested during the life of the battery
○ water should not need adding during the life of the battery
○ terminal should never be cleaned during the life of the battery
○ battery box and hold downs should never be removed during the life of the battery

Explanation:

Maintenance - free batteries are designed so that water does not need to be added. This is a key characteristic. Testing the charging system (which is related to battery performance), cleaning terminals (for good electrical connection), and handling battery box and hold - downs (for proper battery placement) are still important maintenance tasks that may be required at some point.

Answer:

Water should not need adding during the life of the battery.
