Battery Maintenance - jcb JS300 Service Manual

To ensure that the battery provides optimum performance
the following steps should be observed:
1 Make sure that the electrical connections are clean
and tight. Smear petroleum jelly on connectors to
prevent corrosion.
2 When applicable - never allow the electrolyte level to
fall below the recommended level - 6 mm (1/4 in)
above the plates. Use only distilled water for topping
up.
3 Keep the battery at least three quarters charged,
otherwise the plates may become sulphated
(hardened) - this condition makes recharging the
battery very difficult.
Extra precautions must be taken when bench charging
maintenance free batteries, they are more prone to
damage by overcharging than the standard type of battery:
– Never boost-charge a maintenance free battery.
– Never charge a maintenance free battery at a voltage
in excess of 15.8 Volts.
– Never continue to charge a maintenance free battery
after it begins to gas.
