Section 6 Maintenance
You must not allow your batteries to become completely
discharged. As a battery discharges, the active
material on both positive and negative plates changes
to lead sulfate, causing the plates to become similar in
chemical composition. The battery electrolyte becomes
weaker and the voltage drops. As the battery remains
discharged, this process continues until recharging the
battery becomes impossible.
If the battery does become discharged, be sure to
recharge it as soon as possible. vercharging a battery
can also reduce its effective life.
