Product Specification Model No.: GPRHCH53D004
Document Number: TQS4829 Revision: 01 Page 2 of 5
1. SCOPE
This specification governs the performance of the following GP Rechargeable Nickel Metal Hydride
Cylindrical Cell and its stack-up batteries.
GP Model:
GP55AAAHCR2BMX-2+9058
Cell Size: AAA
The data involving nominal voltage and the approximate weight of the stack-up batteries shall be equal to
the value of the unit cell multiplied by the number of cells in the battery. For example, a stack-up battery
consists of eight unit cells:
Nominal voltage of unit cell = 1.2 V
Thus, nominal voltage of stack-up battery = 1.2 V × 2 = 2.4 V

3. PERFORMANCE
Before proceed the following tests, the cells should be discharged at 0.2C to 1.0V cut-off. Unless otherwise
stated, tests should be done within one month of delivery under the following conditions:
