1 BATTERY CHARGING Battery information DDBattery 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 11 hours UHF 10 hours 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. DDBattery icon Icon Battery status The battery has sufficient capacity. The battery is exhausted a little. The battery is nearing exhaustion. The battery is almost fully exhausted. Immediately charge the battery pack. LLAfter a while, the icon blinks and the transceiver will be turned OFF. LL" " is displayed while using the optional AD-149H external power supply. DDAttention 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. 1-2
