The readings should be at or above the factory specification of 1.277 +/- .007. If any specific gravity
readings register low, then follow the steps below.
1. Check and record voltage level(s).
2. Put battery(s) on a complete charge.
3. Take specific gravity readings again.
If any specific gravity readings still register low then follow the steps below.
1. Check voltage level(s).
2. Perform equalization charge. Refer to the Equalizing section for the proper procedure.
3. Take specific gravity readings again.
If any specific gravity reading still registers lower than the factory specification of 1.277+/- .007 then one or
more of the following conditions may exist:
1. The battery is old and approaching the end of its life.
2. The battery was left in a state of discharge too long.
3. Electrolyte was lost due to spillage or overflow.
4. A weak or bad cell is developing.
5. Battery was watered excessively previous to testing.
Batteries in conditions 1 - 4 should be taken to a specialist for further evaluation or retired from service.
II. Open-Circuit Voltage Test
For accurate voltage readings, batteries must remain idle (no charging, no discharging) for at least 6 hrs,
preferably 24 hrs.
1. Disconnect all loads from the batteries.
2. Measure the voltage by a DC voltmeter.
3. Check the state of charge with Table 1.
4. Charge the battery if it registers 0% to 70% charged.
If the battery value is lower than that in Table 1, the following conditions may exist:
1. The battery was left in a state of discharge too long.
2. The battery has a bad cell.
Batteries in these conditions should be taken to a specialist for further evaluation or retired from service.
