relative humidity about 45%
～
85%. Store in high temperature may cause
leakage, store in high relative humidity may cause corrode.
The capacity of the battery may be lower after along time storage. Charge
and discharge the battery for several times can get back the capacity. We
recommend you discharge and charge the rechargeable battery for one time at
least when you have stored the battery more than half year.
6.2 Notice:
6.2.1 Charging
1) The charging efficiency is affected by the environment. Charging in the
temperature about 10
o
C
～
30
o
C may has the best efficiency. It may cause the
leakage
、
lower the capability or the cycle life of the battery if charge it in the
temperature under zero. The charge efficiency may drop sharply when charge
the battery in the temperature higher than 40
o
C, also it will cause the leakage
、
lower the capability of the battery. It may cause leakage and lower the capacity
if charge the battery in the temperature too high.
2) Never short circuiting the cells, use the correct polarity when charging, or it
may cause the deformation
、
leakage even the explosion.
3) The maximum current of external quick charging must within 1C.must use
the specified adapter to charge the battery or it may cause overheating
、
leakage
、
even explosion.
4) The range of current slow charging on printer should be 1/30C
～
1/20C. The
charging time should not exceed 20 hours.
6.2.2 Discharging
1 The battery discharging temperature could be –20
o
C
～
60
o
C. The best
discharging temperature is 0
o
C
～
40
o
C
2 The best discharging current is 1/10C
～
1C, th e maximum continuous
discharge current should not exceed 3C. Too high discharging current may
drop down the discharging efficacy and heat the battery.
3 Do not over-discharging, it may cause leakage, drop down the cycle life even
cause explosion.

Explanation:
C=rated charging current (or discharging current)/hour
=rated capacity mAh/h
For example: for a 1500mAh battery,
1C=1500mA
0.4C=600mA
0.1C=150mA
