Charging instructions
950009D
Charge Voltage: Limit the maximum charge voltage to 4.2V times the number of
cells connected in series. This charging voltage is noted on the product
specification sheet.
Charge current: Packs should be charged at C rate for lithium-ion cells. C is the
nominal capacity of the pack. (Example: for a 2400 mAh cell, charge at 2.4A).
Pre-charge: If the cells are deeply depleted (less than 2.9V per cell), packs should
be charged at 10% of their capacity (Example: for a 2400 mAh cell, charge at 240
mA) until reaching 3.0V per cell when charging can be continued as stated above.
Charge temperature: Do not charge lithium ion cells at less than 0°C or more than
45°C.
Reverse polarity: When connecting the cells to a charger, verify proper polarity.
Charge method: Lithium ion cells should be charged using a constant
current/constant voltage (CC/CV) method. Apply the charge current as stipulated
above in step 2 until the pack reaches the voltage measured in step 1. Then, hold
the voltage constant until the current tapers down to about 5% of nominal capacity
(Example: for a 2400 mAh cell, charge until current is 120 mA).
