Test conditions

All tests shall be done under temperature: 15℃~35℃, relative humidity: (RH)

25%~85%, air pressure: 86kPa~106kPa except special appointment.

Measuring apparatus

Voltage is measured by DC Voltmeter whose precision is higher than 0.5 grade

and self resistance is higher than 1kΩ/V;

Current is measured by Amperemeter whose precision is higher than 0.5 grade;

Temperature is measured by Thermometer which has proper measuring range and

its division value is lower than 0.5℃;

The time used in measuring should be degreed in hour, minute or second, and should have degree of accuracy no less than ±1%.

Standard charge

Charge the battery with DC stable power supply 14.6V, constant current 20A until current reach to 0.05C(A).

Standard discharge

Charge battery by (3-3), discharge the battery with constant current 100A until the battery reach to over discharge protection or total voltage reach to 10V.

Battery capacity

Discharge battery by (3-4), and write down discharge time (hour), then capacity (Ah)=100A * discharge time (hour).

Test Method

Technical requirement

20℃ discharge capacity

Battery charge with standard methods, discharge at 100A, write down discharge capacity.

≥95% nominal capacity

55℃ discharge capacity

Battery charge with standard methods, stored for 5h in 55℃±2℃, then discharge at 100A to cut-off voltage, write down

discharge capacity.

≥80% nominal capacity

Charge retain ability

and recover capability

Battery charge with standard methods, stored for 28d in normal temperature 7d in 55℃.

capacity retention rate≥80% capacity recover rate≥90%

Cycle life

Under the condition of 20℃±5℃, charge

the battery with 0.2C(A); discharge the

battery at 100A to cut-off voltage. Repeat the above test cycle till the retained

capacity is 80% of initial capacity.

≥6000 cycles

Maintenance

If the battery pack needs to be stored for a long time,

charge the battery to 50% SOC (after discharge,

charge by charger

for 2~3h every 3 months).

Battery pack and the charger should be stored in a clean, dry and ventilating place,

and should not be placed together with corrosive

material, keep the battery away from fire and heat

source.

Battery pack and charger should be transported

after packaging, and should avoid severe vibrating,

impacting, extrusion, direct light and rain. They can be transported by automobile, train, ship, plane, etc..

state-of-charge.

maintenance, don’t assemble and disassemble the battery

without permission, otherwise, the performance of battery

will be descend.

The battery pack should be stored in 40%~60%

5. Warnings

Do not immerse the battery into water or seawater.

Do not use, leave or charge the battery near a heat source such as fire or heater.

Do not inversely connect positive and negative polar.

Do not put the battery in fire or heat the battery.

Do not short-circuit the battery with wires or other metals.

Do not pierce the shell with nails or other sharp objects. Do not hammer or tread the pack.

Do not disassemble the battery pack without permission.

Do not put the battery pack in microwave oven or pressure vessels.

Do not use the battery in extremely thermal environment, such as direct light or cars in hot day. Otherwise, the battery will overheats and the performance and life of battery will be influenced.

If the battery leaks or smells, move it away from open fire.

The battery should be used after fully charged in the first use.

If the battery pack smells, fevers, out of shape, color changes or any other abnormal phenomena happen when the battery is being charged or used, please take it out of the charger or electrical equipment.

If the battery leaks and the electrolyte contacts eye, do not rub eye. Instead, rinse eye with clean water, and seek medical attention immediately.

*Temperature will influence discharge capacity, if the temperature exceeds standard environment

temperature (25±°5℃), discharge capacity will reduce.
