Electrolyte Maintenance
Low electrolyte levels in batteries result in accelerated battery-grid
growth, which increases the potential for inter-cell rupture and sparking,
battery explosion, and fire.
Always wear a face shield, gloves, and protective clothing when servicing
battery electrolyte. The electrolyte is a solution of acid and water. Skin
contact should be avoided!
Add ONLY distilled water, NEVER sulfuric acid!
Plates in an 8D battery absorb electrolyte when the battery is less than
fully charged. Adding water to a dead or partially charged battery
can result in boiling or overflow of the electrolyte when the battery is
charged. Water should be added to a battery when it is fully charged. If
it becomes necessary to add water to a dead battery, add only enough
water to cover the tops of the plates, then add water to the fill line once
a full charge is reached. Avoid overfilling, especially in hot climates,
because heat causes the electrolyte to expand and overflow.
Filling Instructions
Do not overfill. Follow the battery manufacturer’s suggested filling procedure. If none is shown, then fill
to 1/8" to 1/4" below the bottom of the filler tube. See Figure 9- 3 below. The plates need to be covered
at all times.
Check fluid periodically, more frequently in warm
environments and in busses with high duty cycles.
Electrolyte in “maintenance-free” batteries is
boiled off at a lower rate during charging
than electrolyte in conventional batteries,
but must still be checked periodically.
