If you use a walkie-talkie battery that doesn't match or pays attention to save, the battery will run out when you don't say a few words. The following methods can save battery consumption: First, try to avoid unnecessary functional operation; Second, avoid frequent shutdown and turn on the power, turn on the walkie-talkie is a large power consumer; Third, do not transmit for a long time during the call, do not Nothing to use the walkie-talkie as a chat tool; Fourth, charge the battery when charging, if the intercom is charged, the walkie-talkie should be turned off; Fifth, please use the original walkie-talkie standard battery or the manufacturer of the walkie-talkie battery manufacturer. Battery; sixth, try to charge the radio when the battery is exhausted, reduce the number of charging to help extend the battery life; seventh, the battery does not enter the tide

The regular manufacturer's NiMH/NiCd battery chargers are controlled by independent MCU, constant current charging and -ΔV. When charging starts, it lights up red, the fast charging current is 0.5-1A, and the slow charging current is 250mA. After charging, it turns green. After turning green, there is still a small current of about 20mA trickle charging to prevent the battery from staying in the charger. After a long time, the power consumption is reduced and the usage time is shortened. The lithium battery charger adopts independent MCU control, constant current and constant voltage charging mode. During the constant voltage charging phase, the charging current is gradually reduced. When the current is reduced to about 100 mA, the battery charging ends and the charger turns to the green light. So it takes no more to charge for an extra hour.
