Battery Specific Gravity Test - Polaris RANGER EV 2015 Service Manual

15. Refer to Table 5. If ambient temperature recorded
earlier was below 80° F, multiply discharge time in
minutes by the multiplier value in Table 5 that
corresponds to that temperature. Record Adjusted
Discharge Time.
At peak capacity, the discharge cycle time will be
about 220 minutes (3 hours and 40 minutes). If the
Adjusted Discharge Time is greater than 175 minutes
(2 hours and 55 minutes) the battery pack is in good
to excellent condition, and no further testing is re-
quired. If the adjusted discharge time is LESS than
175 minutes, proceed to the next step - Battery
Testing.

BATTERY VOLTAGE TESTING (LOADED)
16. Have a digital voltmeter ready and set to Volts DC.
17. Press START/STOP to re-start the discharger and
test battery voltages under load. A 3-minute test
cycle will begin, allowing ample time to test all (8)
batteries.
18. Connect red meter lead to positive and black meter
lead to negative terminal post of each individual
battery. Record voltage reading in the table below.
19. Replace any battery with a voltage less than 9 volts.

BATTERY SPECIFIC GRAVITY TEST

A Specific Gravity test measures the density of battery
electrolyte in relation to water (water = 0). Specific gravity
is the best indicator of battery condition and can identify
a weak cell or cells in an individual battery.
A temperature-compensated digital or a numerically
graduated hydrometer is required for this test. Floating
ball types cannot be used.
