2. BATTERY INFORMATION

2.1 Charging the Battery Pack

The Li-ion battery pack is not charged at the factory; please charge it before use.
Charging the battery pack for the first time after purchase or extended storage (more than 2 months) may not bring the
battery pack to its normal maximum operating capacity. Best operation will require fully charging/discharging the battery
two or three times before the operating capacity will reach its best performance. The battery pack life may be depleted
when its operating time decreases even though it has been fully and correctly charged. If this is the case, replace the battery
pack.

2.2 Charger Supplied

Please use the specified charger provided by Baofeng. Other models may cause explosion and personal injury. After
installing the battery pack, and if the radio displays low battery with a red flashing lamp or voice prompt, please charge the
battery.

2.3 Use Caution with the Li-ion Battery

(1) Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery
pack, as Baofeng cannot be held responsible for any accident caused by modifying the battery.
(2) The ambient temperature should be between 5℃-40℃ (40˚F - 105˚F) while charging the battery. Charging outside this
range may not fully charge the battery.
(3) Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
(4) To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until
the green light is on.
(5) Do not recharge the battery pack if it is fully charged. This may shorten the life of the battery pack or damage the battery
pack.
(6) Do not charge the battery or the radio if it is damp. Dry it before charging to avoid damage.
