Product Specification Model No.: GP70AAAH
Document Number: PQS3401 Revision: 03 Page 1 of 4
1. SCOPE
This specification governs the performance of the following GP Nickel-Metal Hydride Cylindrical Cell and its
stack-up batteries.
GP Model: GP70AAAH
Cell Size: AAA
The data involving nominal voltage and the approximate weight of stack-up batteries shall be equal to the value of the unit
cell multiplied by the number of unit cells in the battery. For example, a stack-up battery consists of three unit cells:
Nominal Voltage of unit cell = 1.2V
Thus, nominal voltage of stack-up battery = 1.2V x 3 = 3.6V
For batteries which has 2 cells or above per pack, capacity may not have the below stated minimum capacity due to
increased in impedance from inter-cell connection and protection components.

charge/over discharge.
6. Avoid batteries being used in an airtight compartment . Ventilation should be provided inside the battery
compartment ; otherwise batteries may generate hydrogen gas, which could cause an explosion if exposed to an
4
ignition source.
7.
Do not attempt to take batteries apart or subject them to pressure or impact, Heat may be generated or fire may
result. The alkaline electrolyte is harmful to eyes and skin,and it may damage clothing upon contact.
8. Keep away from children .If swallowed ,contact a physician at once.
9. Do not short circuit batteries , permanent damage to batteries may result.
10. Do not incinerate or mutilate batteries ,may burst or release toxic material
11.
Do not solder directly to cells or batteries.
12. Store batteries in a cool dry place.
13.
If find any noise , excessive temperature or leakage from a battery,pleasse stop its use.
14. When not using a battery, disconnect it from the device.
15.
When using a new battery for the first time or after long term storage , please fully charge the battery before use.
16. Do not mix new batteries in use with semi-used batteries , over-discharge may occur.
17.
When connecting a battery pack to a charger , ensure correct polarity.
18. When the battery is hot , please do not touch it and handle it , until it has cooled down.
19.
Do not remove the outer sleeve from a battery pack nor cut into its housing.
20. When find battery power down during use , please switch off the device to avoid over discharge.
21.
Unplug a battery by holding the connector itself and not by pulling at its cord.
22. After use , if the battery is hot ,Before recharging it , allow it to cool in a well-ventilated place out of direct sunlight.
23.
Never put a battery into water or seawater.
In order to maintain satisfactory cell / battery performance when being stored under extending period of time,
24.
cycling (i.e. charging and discharging ) of the cell / battery within 6 months period is highly recommended. At least
one times cycling should be conducted within one year .
