Battery Packs
Information on rechargeable batteries
• When the battery pack is new it will not provide 100% of its efficiency. To reach the full battery run
time you have to “run-in” the battery with at least 3-4 deep charging/discharging cycles. After that
it will reach its maximum capacity. Please see “Proper charging of battery packs” for further
details.
• When you properly use the battery pack, you will obtain about 400 charge/discharge cycles (300
with the optional rapid charger). The battery “run time” will progressively reduce after 2/3 of its life
(approx.).
• Rechargeable battery packs lose their charge with time if left unused (self-discharge), this is
normal. A NiMH (Nickel Metal Hydride) battery can reduce 10 to 20% of its stored energy in few
days.
Proper charging of battery packs
1) Ensure that the radio is switched off,
5) Insert the radio into the cradle as explained in the paragraph “Charging the battery pack”
6) Wait the necessary time to provide a full charge. If the pack isn’t completely discharged you will need
less than 8 hours.
, Do not overcharge the battery: always remember to remove the radio after the necessary time.
, The battery charger is for indoor use only.
When possible, charge the battery only when it is fully discharged or, at least, you have used it for
the major part of the day, otherwise the battery’s “run time” could be temporarily reduced.
Do not remove the radio before the necessary time, otherwise the battery’s “run time” could be
temporarily reduced.
• When possible charge battery packs only when they are completely discharged, i.e. when the
battery icon has no bars inside.
• Do not remove the battery from the charger before the necessary time to provide a full charge.
• Provide at least two deep charge/discharge cycles per month.
