Battery Specific Gravity Test; Battery Charging Procedure - Polaris RANGER 1000 2020 Service Manual

CHASSIS / BODY ELECTRICAL

BATTERY SPECIFIC GRAVITY TEST

A tool such as a Battery Hydrometer (2870836) can be
used to measure electrolyte strength or specific gravity.
As the battery goes through the charge / discharge cycle,
the electrolyte goes from a heavy (more acidic) state at
full charge to a light (more water) state when discharged.
The hydrometer can measure state of charge and
differences between cells in a multi-cell battery.
Readings of 1.270 or greater should be observed in a
fully charged battery. Differences of more than .025
between the lowest and highest cell readings indicate a
need to replace the battery.

BATTERY CHARGING PROCEDURE

If battery voltage is 12.6 Vdc or less, the battery may
need recharging. When using an automatic charger, refer
to the charger manufacturer's instructions for recharging.
Recommended Charging Rate: 1 hour @ 6-10 Amps.
Do not exceed 10 amps when charging the battery.

NOTICE
Charge the battery using an automatic charger that will
not exceed 14.6 Vdc. An automatic charger will signal
when charging is complete.
Allow the battery to stand disconnected for at least 1-2
hours after being properly charged. If the voltage drops
below 12.6 volts, charging was ineffective or the battery
needs to be replaced.
DANGER
An overheated battery could explode, causing severe
injury or death. Always watch charging times carefully.
Stop charging if the battery becomes very warm to the
touch. Allow it to cool before resuming charging.
