1: Ta: Ambient Temperature
2: Approximate charge time from discharged state, for reference only.
3: IEC 61951:2003 Cycle Life Test:
|49||0.25C× 3hrs10mins||None||0.25C× 1.0V/cell|
|Cycles 1 to 50 shall be repeated until the discharge duration on any 50th cycle becomes less than 3hrs|
(1) Reverse charging is not acceptable.
(2) Charge before use. The cells/batteries are delivered in an uncharged state.
(3) Do not charge/discharge with more than our specified current.
(4) Prevent short circuit, do not incinerate or disassemble the cell/battery.
(5) Do not solder directly to the cell/battery for a long time.
(6) The life expectancy may be reduced if the cell/battery is subjected adverse conditions like: extreme temperature, deep cycling, excessive overcharge/ over-discharge.
(7) Store the cell/battery in a cool and dry place. Always discharge batteries before assemble or solder.
(8) Always discharge batteries before bulk storage or shipment.
(9) Do not mix batteries of different types and capacities.
