4. TEST CONDITIONS
Unless otherwise specified, all tests should be conducted within one month of delivery under the following
conditions:
Ambient Temperature
: 23 ± 5°C
Relative Humidity
: 65 ± 20%
5. TYPICAL CHARACTERISTICS
Item Capacity Internal Impedance
Typical discharge capacity at different temperatures
Criteria ≥ 2550 mAh
≤ 60 mohm
-10°C 0°C 25°C 40°C
60% 80% 100% 90%
Test Conditions
Standard charge and standard discharge Measure AC impedance at 1kHz within 1 hour after standard charge
Standard charge cell at 23 ± 5°C. Place cell in the temperature to be tested for 2 hours and then discharge cell at Standard charge.
Cycle Life, 23°C
> 70%
Measure discharge capacity after conducting 350 cycles of standard charge/discharge.
Storage characteristics
≥ 80% (retention) ≥ 90% (recovery)
Measure discharge capacity (retention) of cells after standard charge to 100% SOC and stored at 23 ± 2°C for
28 days. After that, charge the cell at standard condition and measure capacity (recovery) under 23 ± 2°C condition.

6. WARRANTY
One year limited warranty against workmanship and material defects. The information ( subject to change without prior notice ) contained in this document is for reference only and should not be used as a basis for product guarantee or warranty. For applications other than those described here, please contact your nearest GP Sales and Marketing office or Distributors. Manufacturer reserves the right to alter, amend the design, model and specification without prior notice.
7. STATUS OF CELLS AS OF EX-FACTORY
Charge from 30% to 50% according to delivery condition.
The cell should be shipped in 3.50V ~ 3.90V charging voltage range.
8. SAFETY PRECAUTION
Please follow the safety precaution carefully as improper handling of lithium ion batteries may result in injury or damage from electrolyte leakage, heating ignition or explosion. To ensure safety, consult with GP regarding the charge and discharge specifications, equipment structure, warning labels and other important details when designing equipment to use GP rechargeable lithium ion batteries.
Never charge the battery above 4.20V. Never reverse charge the battery. Never heat or incinerate the battery. Never pierce, crush or cause mechanical damage to the battery. Never charge a battery at high temperature condition, such as under the blazing sun or near a fire. Never short circuit the battery. Never discharge a battery to below 2.75V per cell. Stop discharge a battery when cell temp above 65°C. Never allow the battery to get wet or be immersed in water. For long period of storage, temperature should be below 25°C. After long period of storage, battery may require some cycling to recover capacity.
