BATTERY CHARGING
Battery information
D Battery life
The approximate battery life (operating time) as
shown below is calculated under the following
assumptions:
• Power save setting: Auto
• Duty cycle: TX : RX : Standby = 1 : 1 : 8
(based on operating style)
The approximate battery life of the BP-280:
VHF
UHF
NOTE: BE SURE to replace the battery pack with
a new one approximately five years after purchase,
even if it still holds a charge. The material inside the
battery cells will become weak after a period of time,
even with little use.
The estimated number of times you can charge the
pack is between 300 and 500. Even when the pack
appears to be fully charged, the operating time of the
transceiver may become short when:
• Approximately five years have passed since the
pack was manufactured.
• The pack has been repeatedly charged.
TIP: Keep the battery terminals clean. It's a good
idea to clean them occasionally.

D Attention to the swelled battery pack
The battery cells may deteriorate and swell due to
their characteristics if used in an environment and
conditions such as: frequently charged, recharged
immediately after full charge, used or saved in a
hot place, or charged by methods other than the
instructions.
If the battery pack swells, it has reached the end of its
life due to deterioration. Replace it with a brand new
one.
