Battery life guidelines
Battery (rechargeable)
During daily use, always keep the battery fully charged and away from
hot areas.
Keep the battery terminals dry and clean.
Never discharge beyond the specifications of the battery.
Operation/Standby time depends on usage. Generally, the more the radio
is transmitting, the faster it will drain the battery. Also, the “Hi” power
setting will drain the battery faster than the “Lo” setting.
Approximate figures are:
• A battery can be stored for 4 to 6 month at 25°C if charged to 40%.
• The battery will normally last for 5 to 9 hours of use on a fully
charged battery.
Note
New batteries should be placed in the charger CH3505, CH3507
or CH3508 for minimum 12 hours first time.
