In Case of Problems

If there is no operation, that is, no LED activity or indication of a

test cycle, try the following:

1. Remove then reinsert one of the tester’s internal (AA) batteries.

Verify that all batteries are installed in the correct orientation.

2. Verify that the battery you are testing is positioned correctly and

its terminals are clean.

3. Check a known good battery. If the battery you are testing is

completely discharged (less than 1% of capacity), the tester will

not start a test cycle.

About Rechargeable Batteries

Capacity

This is the total amount of stored energy that is available from a fully

charged cell or cells. A battery’s usable capacity is dependent upon

the rate of discharge, temperature, and the specied cut-off volt-

age. Most batteries have a rated capacity, expressed in amp-hours,

that is based on a specied constant discharge rate to a specied

cut-off voltage. Capacity will decrease at higher rates of discharge

and increase with lower rates of discharge. New rechargeable bat-

teries require several (3-4) charge-discharge cycles followed by

oat charging to achieve optimum/maximum capacity.

Self-Discharge

All rechargeable batteries will lose capacity over time through self-

discharge. The self-discharge rate is a function of cell chemistry

and storage temperature. Thus a new, fully charged battery which

has been stored for a period of time may test less than 100% until

it is recharged.

Battery Life

Rechargeable batteries will lose capacity through aging, and the

number of charge-discharge cycles experienced by the battery. A

battery’s ability to take/accept a full charge deteriorates throughout

the life of the battery. Therefore, an aging battery that has been

recently charged may only test at 60% or less of full capacity. Oth-

er factors that affect capacity are the depth and rate of discharge,

operating temperature, and charging method.
