• Equation battery charging is used to restore a battery to
its full potential. However, it should not be performed too
frequently. Frequent equation battery charging will result in a
greatly reduced battery service life.
NOTE:
• The battery consists of lead cells connected in series to one
another. Each cell has a capacity of approximately 2 volts. There are
several dozen cells. The connected cells are contained in the battery
case. When there is signicant variation in voltage and battery uid
specic gravity between individual battery cells, full charging will not
be possible.
• With some battery charging equipment, equation battery charging
occurs automatically after some specied number of charge/
discharge cycles. Manual selection of the equation battery charging
mode is not required.
Supplementary Battery Charge
Supplementary battery charging is used when the original single
battery charge is not sufcient to get through the entire work day. It is
performed at some time during the work day (example; during the lunch
break). Supplementary battery charging techniques are identical to
those for normal battery charging.
CAUTION
!
• Supplemental battery charging could shorten battery life if
not recommended by battery manufacturer.

GENERAL CARE AND MAINTENANCE
BATTERY CHARGE CLASSIFICATIONS
Normal Battery Charge
The normal battery charge is used to restore the battery to its original
power level.
Equation Battery Charge
When the normal battery charge is applied many times, the voltage
level and the battery uid specic gravity of the individual cells will
show a wide variation. This wide variation will prevent full charging of
the battery. Equation battery charge is used to equalize individual cell
voltage and battery uid specic gravity and make full battery charging
possible again.
As a general rule, a battery charged and discharged on a daily basis
should have equation charging applied after every 10 or 15 charge/
discharge cycles.
Additionally, equation charging should be performed as soon as
possible if any of the following conditions occur.
a. Battery discharge in excess of the specied limit.
b. Battery charging following discharge is delayed for an extended
time period.
c. A battery short circuit has occurred.
d. A battery that has not been used for an extended time period is
readied for use.
