*** Refer to “Charge Methods for Ni-Cd Batteries”
Battery performance and cycle life are strongly affected by how they are
used. In order to maximize battery safety, please consult Panasonic when
determining charge / discharge specs, warning label contents and unit
design.
Note:
[It] was previously expressed as [C]. [It] is an IEC standard expression
for the amount of charge or discharge current and is expressed as:
It(A) = Cn (Ah)/1h.
• [It] is the reference test current in ampres
• [Cn] is the rated capacity of the cell or battery in Ampere-hours.
n = the time base [hours] for which the rated capacity is declared
Charge: 5000mA(1It)x 1.5hrs., 20˚C.
Discharge Temperature: 20˚C.
