Battery Service General Rules

^ Do not charge the battery if the hydrometer is clear or yellow tap the hydrometer lightly to dislodge any gas bubbles. If the indicator is still clear or yellow, replace the battery.

NOTE: Care should be taken not to allow excessive charge rates. Do not allow charge settings to exceed 80 amps or the temperature of the battery to exceed 52°C (125°F). Failure to follow these guidelines will result in damage to the battery.

^ Charger settings between 3 and 80 amps are acceptable as long as electrolyte does not spew out of the vents or the battery does not feel excessively hot (over 52°C [125°F]).
^ The battery is sufficiently charged when the green dot in the hydrometer remains visible.




^ Do not tilt battery at more than a 45° angle.
^ Make sure the battery hold-downs are tight. Loose hold-downs will shake the plate material off the grids and shorten battery life.
^ Repeatedly discharging the battery (deep-cycling) will shorten battery life.
^ Battery shield must be installed to protect the battery from heat.
