7. Environmental Adaptability
Discharge capacity
Put the battery at 40℃±5℃ and 95%RH chamber after storage is more
for 48h, then get it out and store it for 2h at room than 90% of rated
2 Static Humidity capacity. No obvious
temperature. Observe the appearance and discharge
at 0.5C to 2.5V, then test the final capacity. outside damage, No
corrosion, No smoke,
No explosion
Residual Capacity≥90%
Standard charge. Equip it to the vibration platform,
prepare the test equipment according to following Rated Capacity
vibration frequency and relevant swing, doing Voltage Decrease Rate
frequency sweeping from X, Y, Z three directions, ≤0.5% Internal Resistance
each from 10Hz to 55Hz for 30 minutes of Increase Rate≤20%
recycling, rating of which is 1oct/min:
3 Vibration
A)vibration frequency:10Hz~30Hz
Displacement breadth (single swing): 0.38mm No obvious outside
B)vibration frequency:30Hz~55Hz damage, No leakage, No
smoke, No explosion.
Displacement breadth (single swing): 0.19mm.
Observe the final state after scanning.

10. Notice in Using Battery
Please pay attention to followings in case of battery will have leakage, heat etc.
Do not immerse the battery in water or seawater, and keep the battery in a cool dry surrounding if it stands by.
Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or its
performance will be degenerate and its service life will be decreased.
Do not reverse the position and negative terminals.
Do not connect the battery electrodes to an electrical outlet.
Do not short circuit. Otherwise it will cause serious damage of the battery.
Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
Do not strike, trample, throw, fall and shock the battery.
Do not directly solder the battery and pierce the battery with a nail or other sharp objects.
Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety
devices may be damaged, causing hidden trouble of safety.
Use the battery charger specifically when recharging.
If the battery leaks and the electrolyte gets into the eyes, do not rub the eyes, instead, rinse the eyes with clean
water, and immediately seek medical attention. Otherwise, it may injure eyes.
If the battery gives off strange odor, generates heat, becomes discolored or deformed, or in any way appears
abnormal during use, recharging or storage, immediately stop charging, using, and remove it from the device.
In case the battery terminals are dirty, clean the terminals with a dry cloth before use. Otherwise poor
performance may occur due to the poor connection with the instrument.
Tape the discarded battery terminals to insulate them.
Note
The definitions of some nomenclatures of this specification:
(1) Standard charge: 0.5C charge at 25℃±2℃ to 3.65V, then change to charge with constant voltage till the
current less than or equal to 0.01C.
(2) Initial state: battery initial voltage, internal resistance and appearance.
(3) Final state: battery final voltage, internal resistance and appearance.
(4) Residual Capacity: The first discharge capacity after being tested by the specific procedure.
(5) Standard cycle: charge at 1C, then store for 30min, discharge at 1C to the 2.5V.
(6) Recovery Capacity: The discharge capacity by specifically charge-discharge cycle repeatedly after being tested
by the specific procedure.
(7) All batteries tested above are within 60 days unless there are other regulations. Otherwise, part of the electrical
properties may be inconsistent with the above parameters (For instance, discharge capacity of the batteries may
be less than the minimum calibration capacity after 6 months).
