4.Standard Test Conditions
Battery test must within 1 month after production.
All test in this specification should be in standard atmospheric conditions: temperature:
25± 5℃, relative humidity: 65±20%.
5. Characteristics
5.1 Standard charge
Charge the battery with Lithium ion battery special test cabinet, supply 3.65V voltage, constant-current
0.2C(A) current until current down to 0.02C(A).
5.2 standard discharge
Discharge the battery at 0.2C(A) to 2.50V or battery cut off voltage.

6. Characteristic curve
7. Cautions
7.1Charging current should be less than maximum charge current specified in the Product Specification,
Charging current bigger than recommended current may damage the battery;
7.2Discharging current should be less than maximum discharge current specified in the Product
Specification;Discharging current bigger than recommended current may damage the battery;
7.3 It should be noted that the cell would be possible to be at a over-discharged state by its
self-discharge characteristics in case the cell is not used for long time. In order to prevent
over-discharging, the cell shall be charged periodically to maintain between 3.30V and 3.40V
(2month one cycle),Over-discharging may causes loss of cell performance, characteristics, or
battery functions;
7.4 Please charge the battery within 12 hours after use;
7.5 Battery storage environment follow the above conditions and in standard atmosphere, should be
without strong magnet, no power, no static;
7.6 Do not reverse the polarity of the battery pack for any reason;
7.7 Do not short circuit the battery pack;
7.8 Do not reverse polarity charging;
7.9 Do not immerse the battery pack in water or sea water, or get it wet;
7.10 Do not disassemble battery;
7.11 Do not expose the battery to extreme heat or flame;
7.12 Please use special charger for charging;
8. Product Liability
HETER is not responsible for the incident caused by not obeying the specifications. Before using the battery, you should read the specifications, usage instruction and some attentions carefully to learn its application method and areas. If the phenomenon such as error using method or wrong circuit connection,or input power data, working index are inconsistent with the specifications , cause damage to product, load and its accessories, we are not responsible for it.
Our company have the right to change the content of specification without prior notice;
