CAUTION!
Permanent battery capacity loss is greatest at elevated temperatures
with the batteries fully charged. Do not leave batteries installed in
your X10gx in high temperature surroundings with external power
connected for days or weeks at a time. Remove the batteries and
store them in a cool place.
Dis c h a rg e /Re c h a rg e Cyc le s
Lithium ion batteries do not need to be deeply discharged periodically to maintain capacity like
certain other types of rechargeable batteries. In fact, deep discharges have a negative effect on
a lithium ion battery’s capacity and operating life.
Each time a lithium ion battery is deeply discharged (<30%) and then recharged (either during
normal operation or conditioning), the battery records the event as a “cycle.” Each of these
deep discharge/recharge cycles has a small cumulative effect on the overall capacity and life of
the battery and (on average) after approximately 300-400 cycles at nominal room temperature,
the battery is a candidate for replacement (sooner if used primarily in high temperature
environments).
A battery’s accumulated cycles are displayed in the
Charge Cycles Count
field of each Battery
Information window in ARMORutils (see Figure 71).
