ADVANCED EV ADVENT - Battery Fluid and Cable Management

MAINTENANCE
BEFORE CHARGING:
Only add distilled water. If fluid is below
the top of the plates, add just enough to
cover plates.
AFTER CHARGING:
Check that the fluid level is appropriately
1/4 to 1/2 inch above the plates and 1/4 to
3/8 inch below the level is low. Add distilled
water carefully. Adding distilled water after
charging helps prevent boiling over.

Normal tap water contains minerals which

with distilled water.
NOTE:
Only lead-acid batteries
need to add battery water,

do not need.
