All Weijiang NiMH cells undergo comprehensive performance testing. Below are representative discharge and cycle life curves for our standard NiMH cells. Actual performance varies by cell size, capacity grade and operating conditions.
Weijiang NiMH cells maintain over 80% of initial capacity after 1000 charge-discharge cycles under standard conditions (0.5C charge / 1C discharge, 25°C), significantly outperforming the industry average.

Our low-self-discharge NiMH formulation retains approximately 84% capacity after 6 months at room temperature (20°C). Storage at lower temperatures further reduces self-discharge.
Figure 2: Self-discharge rate at different storage temperatures
Representative discharge curves for a D-size (9000mAh) NiMH cell at 0.2C, 0.5C, 1C and 2C discharge rates. The flat voltage plateau ensures stable device operation throughout most of the discharge cycle. Cut-off voltage: 0.9V/cell.
