Battery Safety Notes

Always refer to the battery manufacturer’s recommendation for selecting correct “FLOAT” and “ACCEPT” •

charge voltages. Failure to do so can damage the batteries.

Verify the Power Supply’s battery charger “FLOAT” and “ACCEPT” charger voltage settings.•

Batteries are temperature sensitive. During extremely cold conditions, a battery’s charge acceptance •

is reduced and requires a higher charge voltage; during extremely hot conditions, a battery’s charge

acceptance is increased and requires a lower charge voltage. To compensate for changes in temperature,

the battery charger used in the power supply is temperature compensating.

If the batteries appear to be overcharged or undercharged, ﬁ rst check for defective batteries and then •

verify the correct charger voltage settings.

To ensure optimum performance, inspect batteries every three to six months for signs of cracking, •

leaking, or unusual swelling (note that some swelling is normal).

Check battery terminals and connecting wires. Clean battery terminal connectors periodically and •

retighten to approximately 50 inch-pounds (or to manufacturer’s speciﬁ cations if not AlphaCells). Spray

the terminals with an approved battery terminal coating such as NCP-2.

Check battery voltages UNDER LOAD. Use a load tester if available. Differences between any battery in •

the set should not be greater than 0.3Vdc.

Refer to the battery manufacturer’s recommendation for correct charger voltages and the power supply •

operation manual for corresponding charger settings.

Number the batteries (1, 2, 3, etc.) inside the enclosure for easy identiﬁ cation (refer to the appropriate •

enclosure installation guide).

Establish and maintain a battery maintenance log.•

If installed, disconnect the AlphaGuard prior to measuring battery voltage.

NOTE:

Even with a AG-CMT present in the system, any battery which fails the 0.3V load test must be replaced with

an identical type of battery.
