User Manual
●
If the end-of-charge voltage does not exceed the values above, check the charger
to ensure the proper output is being maintained. Recharge the batteries and mea-
sure again. If the pack voltage is still low, you may have a bad battery.
●
While the pack is on charge, measure the individual battery voltages and compare
to the table below. If the minimum voltage is not attained and/or the variance be-
tween the batteries is greater than the allowable variation, the low battery may be
failing.

8.5 OPEN CIRCUIT VOLTAGE TESTING
This is the least preferred method of evaluating the condition of your battery due to the
misleading nature of open circuit voltages.
●
For accurate voltage readings, flooded lead acid batteries should remain idle
for at least 4-6 hours. AGMs should remain idle for at least 24 hours.
●
Measure the individual battery voltages.
●
If any recorded voltage differs from another battery within the set by more than
0.3V, you may have a failing battery.

QUICK TIP
SINGLE POINT WATERING KITS:
ARE A
GREAT WAY TO REDUCE THE AMOUNT OF TIME IT
TAKES TO MAINTAIN YOUR FLOODED BATTERIES. ALL
BATTERIES CAN BE WATERED FROM ONE SOURCE.
THE VALVES ENSURE THAT ELECTROLYTE LEVELS ARE
PROPERLY MAINTAINED. FOR MORE INFORMATION
