5.6 | LCD Screen: | Short press a switch, light and display screen: voltage temperature residual capacity current, light up after waiting for screen to go out, after 60 s into power saving state (buzzer open state, the buzzer alarm detection background), short press it again to light up the screen. |
5.7 | Buzz: | Buzzer open state: SOC 10% or less, buzzer alarm, long press switch 3 s, buzzer close and screen OFF buzzer hints |
Buzzer is turned off, when the SOC 50% or less, need to manually by 3 s starting buzzer long (SOC testing and determine whether the alarm). |
Buzzer is turned off, charging when the battery pack is SOC > 50%, the buzzer closed automatic reset, in an open position. |

Applications:
Golf trolly of 12v 1200w motor , Wireless camera, surveillance cameras, wireless infrared detector, car LCD TV, portable DVD, personal treatment system, PDA personal data assistant, personal communications systems, walkie-talkies, digital cameras, camcorders, video cameras, Bluetooth devices, CD players, MD players, MP3 players, smart cards, aviation model LED lights and other fields can be used in 12V power.

How to choose a suitable battery pack?
- battery voltage is the same with the original.
- battery size same with the original. Or similar/smaller.
- battery plugs same with the original (check the plug diagram)
Match the above three conditions, in general, this battery can be used.
The larger of MAH, the longer use time. Different voltage, battery size, shape, can be same voltage, because the battery combination of different ways, the shape is not the same. You can leave a message about your old battery, please pay attention!!!
