Remark:

1. The initial discharge test shall commence within 30 days of manufacture. During the stored period, the cells shall be stored under 20±2℃, RH 55±20% conditions.
2. Lot release service output test is conducted by 20Ω continuo us discharging to 0.9volt. The batteries shall not leak during the service life test before the end voltage is reached.
3. MAD: minimum average duration
4. Normal: normal data, batteries discharge value is on this as a base to be upper or lower.

ELECTROLYTE LEAKAGE

1. Over-discharge leakage test
   • Test conditions: 20±2℃ & RH 55±20%, 20Ω continuous discharge 48h.
   • Number of test samples: 9 Batteries
   • Requirement: No visible leakage; No explosion.

1. Test eight batteries.
2. Calculate the average without the exclusion of any result.
3. If this average is equal to or greater than the specified figure and no more than one battery has a service output of less than 80% of the specified figure, the batteries are considered to conform for service output.
4. If this average is less than the specified figure and/or more than one battery has a service output of less than 80% of the specified figure, repeat the test on another sample of eight batteries and calculate the average as previously.
5. If the average of this second test is equal to or greater than the specified figure and no more than one battery has a service output of less than 80% of the specified figure, the batteries are considered to conform for service output.
6. If the average of the second test is less than the specified figure and/or more than one battery has a service output of less than 80% of the specified figure, the batteries are considered not to conform and no further testing is permitted.

   • Requirement: No fire or explosion; Leakage is allowable.

3. Incorrect installation
   This test simulates the incorrect installation of a battery in a series application.

   • Number of test sets: 5 (20 batteries)
   • Requirement: No fire or explosion; Leakage is allowable.

PACKAGING

Packaging shall be a form agreed upon by both parties.

Precaution & Handling

1. 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 the eyes and skin, and it may damage clothing upon contact.
2. Keep away from children. If swallowed, contact a physician at once.
3. Do not mix GP batteries with other battery brands or batteries of a different chemistry such as alkaline and zinc carbon.
4. Do not short-circuit batteries, permanent damage to batteries may result.
5. Do not incinerate or mutilate batteries, may burst or release toxic material.
6. Do not solder directly to cells or batteries.
7. Store batteries in a cool dry place.
8. If find any noise, excessive temperature, or leakage from a battery, please stop its use.
9. When not using a battery, disconnect it from the device.
10. Do not mix new batteries in use with semi-used batteries.
11. When find battery power down during use, please switch off the device and take the batteries out.
12. Never put a battery into water or seawater.
13. Do not recharge batteries.

Storage

1. Store in a cool, dry place before use.
2. Do not keep batteries at a temperature of 45℃ or above.
3. Do not keep batteries at a relative humidity of 75% or above.
