Rechargeable Battery Testing

Rechargeable Battery Review’s means and testing procedures are simple. Every product is treated equally. Our tests are performed using a test platform and uses a fixed load which discharges the rechargeable battery at a rate less than 0.1C.

When rechargeable batteries are received:

1. The rechargeable battery is charged and discharged until no significant increase in capacity is achieved ( +/-2%. For a 2500mAh rechargeable battery, that is +/-100mAh ).
2. The rechargeable battery is tested using the fixed load test .
3. The rechargeable battery fixed load test results are compared to a constant current test in the LaCrosse BC-900 and /or the Maha Powerex MH-C9000 Wizard1 advanced battery chargers.
4. If there is a significant difference between the fixed load test and the constant current test, we go back to step 2.

Rechargeable Battery Review does not expect the fixed load test to yield the same results as the 0.2C constant current test. We do expect however, the results to be within 5% tolerance. The fixed load test results have consistently been within 5% or less of the constant current tests. See the examples below.
