discharge prior to attaining the limit voltage (avoid
over-discharging).
When the operational period of a vehicle is short
during the day, but low speed operation for long
periods is required at night, or when larger lamps
(other than those designated) are used, the extent of
discharge exceeds that of charge. Hence, the battery
should be dismounted from the vehicle and a supple-
montary charge made.
(4) The exterior portion of a battery, especially
around terminals or electrode connectors, should
always be kept clean. Due to dust and residue,
electrical current leaks and over-dischange may
result.

performed following over-discharge.)
2) Negative plate (Refer to Fig. 5. 70)
Cause of sulfation (" non-return " white lead sulfate}
a. Prolonged battery use without charging.
