Cell Safety Performance
Item | Condition | Specification |
Over charge | At 20±5℃, charging battery with constant current 1C to voltage 4V, then with constant voltage 4V till current decline to 0. | No explosion, No fire |
Over discharge | At 20±5℃, according to the requirement of the standard of discharge after discharge to termination No explosion, No fire voltage, 30 m Ω external load discharge within 24 hours. | No explosion, No fire |
Short-circuit | At 20±5℃, Standard charge, across the electrodes of the battery with a less than 50 m Ω wire connection, 6 hours | No explosion, No fire The temperature of the surface of the cell are lower than 150℃ |
Heating | Battery is heated in a circulating air oven at a rate of 5±2℃ per mins to 130℃, an then placed 30 mins at 130℃ | No explosion, no fire |
To prevent the possibility of the battery from leaking, heating, fire, Please READ this specification carefully before:
usage and observe the following precautions:
◎When recharging, use the LiFePO4 battery charger specifically for that purpose
◎Do not strike battery with any sharp edge parts, such as Ni-tabs, pins and needles
◎Do not immerse the battery in water and seawater
◎Do not use and leave the battery near a heat source as fire or heater
◎Do not reverse the position and negative terminals
◎Do not connect the battery to an electrical outlet
◎Do not discard the battery in fire or heat it
◎The battery tabs are not so stubborn especially for aluminum tab. Do not bend tab.
◎Do not short-circuit the battery by directly connecting the positive and negative terminal with metal object.
◎Do not transport and store the battery together with metal objects such as necklaces, hairpins etc.
◎Do not directly solder the battery and pierce the battery with a nail or other sharp object.
