Test Conditions, Methods and Performance
1. Test conditions
All tests were conducted at temperature of 25 ° C, humidity of 25% ~85%, and atmospheric pressure of 86 kPa~106 kPa unless otherwise specified.
2.Measuring instruments
3. Standard charging
Charge with a DC power supply (switching power supply) at voltage of 5.0V, 20C (A) constant current until the current down to 1A.
4. Standard discharge
After charging in accordance with (3.3), discharge at 0.9 (A) current till cutoff.
5. Battery capacity
Discharge in accordance with (3.4), and record discharge time(h), energy (Wh) = power (W) * discharge time (h).
Storage, maintenance and transportation
1 Storage
When the battery pack is to be stored for a long time, charge the battery pack to about 50% of SOC (charging about 2 hours at 30A CC after discharging), and place it in a clean, dry and ventilated place, avoid of contact with corrosive substances, away from fire and heat. Charge/discharge cycle the battery pack every three months.
2 Transportation
The battery pack should be packed with care before transport. Truck, trains, ships, airplanes and other means of transport are permitted for transportation of the battery packs.The cargo should be prevented from severe vibration, shock or squeeze,and sheltered from sun and rain during transportation.
3 Maintenance
Usage Precautions
1 Do not reverse the polarity to prevent short circuit;
2 Do not put the battery pack into water or soak it;
3 Do not charge the battery pack in hot conditions; Do not use or store batteries near heat sources such as fire or heaters;
4 Do not use nails or other sharp objects to pierce the battery pack;hammering or stamping on the battery packs is prohibited.
5 It is forbidden to disassemble the battery packs or cells in any way;
6 If any anomaly should occur to the battery pack such as odor spreading, heat, deformation, discoloration , remove the battery pack immediately from the appliance or charger, and contact the manufacturer;
7 If the electrolyte of battery leaks accidentally and happens to splash into the eyes, do not wipe, but immediately rinse them with water instead, and seek medical assistance in a timely manner for serious cases.
8 Ambient temperature will affect the discharge capacity. If the ambient temperature exceeds the standard environment range(25 ℃ ± 5 ℃), the discharge capacity will be slightly reduced.
