Mobile phone charging precautions

     1:48V new battery requires charger parameters, the highest voltage 58.5 --- 59.7, not less than 58V, less than 58V caused by insufficient charge, higher than 59.7V may cause the charge does not turn on the light. The turn-on current is about 0.4---0.7A, the actual voltage is about 55.5V, less than 50V causes insufficient charge, and the rechargeable battery loses power for a long time

      2:4820 battery requires charging the maximum current of 2.4 ---- 3.3A, less than 2.2A charging, charging effect is poor,

      3: The actual power of the charger less than 30 yuan on the market is small, the parameter design is not accurate, please pay attention to distinguish 2/4 bbs.mydigit.cn/simple/?t478779.html Charger voltage regulator circuit failure will cause the output voltage 75- --130V, hot charging battery does not turn on the light.

      5: When the new battery appears, cruising range 20A battery is less than 30 kilometers 12A battery is less than 25 kilometers please check the charger parameters, if you can not determine yes, please replace the high-quality charger to use again, you can solve the problem

      6: When the new battery encounters no light, please replace another high-quality charger tester.

      7: Under normal circumstances. 4820 new battery charging time is about 10 hours, cruising range 40 --- 60 kilometers, 4812 new battery charging time is about 10 hours, the mileage reaches 25 --- 40 kilometers, if the normal charging time exceeds above, please replace the high-quality charger Use again, feedback

      8: There are a lot of charger internal circuits, input and output connections aging, causing, sometimes able to charge, and sometimes not flush. Seriously affect the battery, or circuit failure during charging, resulting in bulging bag, if this happens, please replace the high-quality charger and use it again. The charger is usually the output line is broken, 2 green lights, this is a good solution. General charger high pressure bomber is also more, generally need to change the power tube, diode, 3842 integrated circuits, and 6-pin drive resistor, m os current limiting resistor. As for the battery water shortage charger does not turn green, it is not necessarily the problem of the charger, the summer battery is much more water. Charging current can not fall down, the charging voltage can not reach the highest turning voltage, will not turn on the light, the fundamental way is to add water to the battery, you can also reduce the charger output voltage constant high, or as long as the turn lamp current is increased Something is fine
