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

  •     Voltage: DC voltmeter of accuracy ≥0.5,inner resistance≥ 1kΩ / V;
  •    Current: DC meter of accuracy≥0.5;
  •    Temperature: thermometer of appropriate range;the scale value should not be greater than 1℃;
  •    Time: Timing meter to show hour, minute, and second,with ± 1% accuracy

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

  • The recommended storage SOC is 40%-60% of rated;
  • It is recommended to charge (at 10A for2 hours ) the battery pack every 6 months for long time storage;
  • Please do not re-assemble the battery pack without the manufacturer’s guidance during maintenance in case of performance deterioration;
  • Please do not disassemble the battery pack; and dissection of the cells is strongly forbidden.

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.
