Icom IC-F3210D Instruction Manual page 29

If your Ni-MH battery pack seems to have no capacity, even after
being charged, completely discharge it by leaving the power ON
overnight. Then, fully charge the battery pack again. If the battery
pack still does not retain a charge (or only very little charge), a new
battery pack must be purchased. (p. 33)
Prior to using the transceiver for the first time, the battery pack must
be fully charged for optimum life and operation.
• Recommended temperature range for charging:
between +10°C and +40°C (rapid charge: with BC-191) or
between 0°C and +45°C (regular charge: with BC-192)
• Use the supplied charger or optional charger (BC-191 for rapid
charging, BC-192 for regular charging) only. NEVER use other
manufacturers' chargers.
The battery pack contains a rechargable battery.
Charge the battery pack before first operating the transceiver, or
when the battery pack becomes exhausted.
If you want to prolong the battery life, the following points should
be observed:
• Avoid over charging. The charging time by the BC-192 should be
less than 48 hours.
• Use the battery pack until it becomes almost completely exhaust-
ed, under normal conditions. We recommend battery charging af-
ter transmitting becomes impossible.
