BATTERY PACKS

Information on rechargeable batteries

• A correctly maintained battery pack will be good for at least 400
charge/discharge cycles.
• All batteries are prone to self-discharge while not being used, a n i c k e l
metal hydride (NiMH) battery may lose up to 20% of the stored charge
within a few days.

Memory effect

The NiMH battery pack supplied with your ALAN HP 446 extrá are virtually
free of memory effect typical od the NI-CD elements. Although continuous
misuse, will eventually lead to a reduction in capacity.
Observing the following procedures will reduce memory effect and prolong
the life of the battery:
• Charge battery packs only when they are fully discharged, ie when
is blinking.
• Do not partially charge the battery.
• Cycle the battery at least once a month ( full discharge followed by a
charge).
• Having a spare battery means that you will always have a fully charged
battery and that both batteries will be in peak condition.

Erasing memory effect

Memory effect may be cured by applying 3-4 deep charge/discharge cycles:
a. Install the battery pack to be cycled on the radio, switch radio on and
leave until the radio switches off automatically, switch the radio off using
the VOL knob.
b. Wait for at least one hour and switch the radio on, leave until the radio
switches off automatically, switch the radio off using the VOL knob.
Repeat this at least three times.
c. Turn the radio off, insert into the base unit of the charger and charge the battery.
