Standard Charging
The CoinPower A4-Version can be standard charged
with a maximum C-Rate of 0.5C over the entire
temperature range between 0 ºC and 45 ºC. The charging
procedure must be Constant-Current Constant-Voltage
(CCCV).
Fast Charging
The CoinPower A4-Version can be fast charged with
a maximum C-Rate of 1C over the entire temperature
range between 15 ºC and 45 ºC. The charging procedure
must be Constant-Current Constant-Voltage (CCCV).
For this charging procedure the performance stated
in the datasheet regarding capacity and cycle life
may decrease.
