For best performance, use fresh alkaline batteries that have been
properly stored and kept away from excessive heat. As with all other
battery-powered electronic items, when the CellCom beltpack is stored
for extended periods of time, remove the batteries to prevent damage
from possible leakage of the alkaline cells.
Caution: Make sure that CellCom battery packs loaded with
alkaline batteries are not put into a battery charger, or that the
internal beltpack charger is used to attempt to charge them.
Damage and possible injury will result.
Rechargeable AA-size NiMH (nickel-metal hydride) batteries may be
used with the CellCom beltpack. Select good quality batteries with high
amperage ratings for the best and longest performance. These
batteries will last for many charge cycles, and will power the beltpack
for approximately 8 hours.
If the batteries are being charged twice daily, then the battery lifetime
would be approximately 8 months or approximately 500 charge cycles.
It is recommended that the batteries be replaced every 4-5 months in
these circumstances (near the end of their service life) as NiMH
batteries can become less efficient with time and may develop an
internal short circuit.
The beltpack charger defaults to trickle charge once the batteries are
fully charged, but some battery manufacturers state a maximum
overall charge time of 20 hours.
Note: If the batteries are hot prior to charging then they will
switch to trickle charge too early in the charge cycle when
the Cel-FS-Charger is used (the green light will come on).
Never mix discharged batteries and fully charged batteries in the same
pack and never mix batteries of different types as this can damage the
charger.
Batteries should not be left in a beltpack and connected to a charger
for more than 20 hours.
Note: CellCom beltpack usage times are dependent upon the
batteries used. Some batteries require more
charge/recharge cycles than others to reach their rated
capacity.
