NiMH Limitations:
•
Limited service life — if repeatedly deep cycled, especially at high
load currents, the performance starts to deteriorate after 200 to 300
cycles. Shallow rather than deep discharge cycles are preferred.
•
NiMH batteries generate more heat during charge and require a
longer charge time than the NiCd. The trickle charge is critical and
must be controlled carefully.
•
NiMH has about 50% higher self-discharge rate as compared
to NiCd.
•
Performance degrades if stored at elevated temperatures.
Lithium Ion ( Li-ion)
The energy density of the Li-ion battery is typically twice that of the
standard NiCd. There is no memory eff ect and no scheduled cycling is
required to prolong the battery's life. In addition, the self-discharge rate is
less than half compared to NiCd and NiMH.
Li-ion Advantages:
•
High energy density.
•
Relatively low self-discharge rate.
•
Low maintenance – no periodic discharge necessary, no
memory eff ect.
Li-ion Limitations:
•
Subject to aging, even if not in use.
•
More expensive than NiCd and NiMH.
•
Discharge rapidly in cold conditions.
Installing and Removing the Battery
To install the battery:
1.
Turn the radio off .
2.
Align the three tabs at the bottom of the battery with the three slots
at the bottom of the back of the radio.
3.
Angle the battery forward toward the radio until the battery clicks
into place.
