Please activate the battery once every 3 months according to the following method:
Charge at 0.1C for 15 hrs, rest 15 min, then discharge with 0.2C to 1.0V/cell, rest 15 min, then charge at 0.2C to
150min.
6. Scope:
All data involves voltage and weight to stack-up battery are equal to the value of unit cell time the number
of unit cell which consisted in the stack-up batteries
Example： Stack-up batteries consisting E unit cells series
Nominal voltage of unit cell=1.2V
Nominal voltage of stack-up batteries =1.2V×1=1.2V
7. Warranty Time.
Warranty time is six (6) months from the date when the Nickel-Metal Hydride battery ship out from
YUNTONG factory. But If the Nickel-Metal Hydride battery is found to have a problem due to use outside
of YUNTONG recommended specification, YUNTONG will have no responsibility for the battery.
8. Others.
Any matters that this specification does not cover should be conferred between both parties.
