         Test Method

1

Full charge

Charge battery with the special charger, until one light on the charger change from red to green .

2

Nominal capacity

15Ah

Make the fully charged battery at 20±5 rest for 0.5~1 hour. Discharge with 3.0A until voltage getting to 28.8V. Five cycles can be made. It can be stopped if discharge time gets to 5 hours in one case.

3

Cycle life

25

Discharge capacity≥9.0Ah

Discharge the battery with constant current 7.5A until 28.8V. then full charge the battery. Discharge the battery with constant current 7.5A until 28.8V. 10 minutes rest and go on the next cycle.2000 cycles altogether.

4

Impedance

Initial:≤200mΩ

Measured with a AC impedance meter of 1 KHz at room temperature 20±5 after fully charged/p>

5

Temperature dependence

The ratio of discharge capacity to nominal capacity shall be more than the value listed on the right.

   Discharge the battery with constant current 3.0A(0.2C) until 28.8V after 8 hours stay on the conditions below.
