Product advantage:

1. In support UPS, the normal usage time for UPS is about 5-15 minutes, however, the usage time for the INV depends on the capacity of the storage battery, The stronger capacity the longer the usage time.

2. Built-in charger is a low frequency intelligence charger, which can filled with electric cell by strong electric current in short time. When the electric cell is already full, which will be entered into floating charging state( means it can charge long time instead of damage the electric cell)

3. Moment conversion: High performance relay can immediately supply the power while power off.

4. Advantage: The porcelin shape, the delicate size, the light weight, and the high converting efficiency.

5. Short-circuit protection, the low voltage alarm, and the electric current cuts off automatically.

6. Built-in fuse, and provide the safe guarantee.

Use the regulation:

1\The charger has been with much protection: such as short circuit protection.However, when the polarities are mixed and mis-connected, for example, the red clip connect the battery cathode, and the black clip  connect the battery anode,then the buit-in fuse will be melted .
2\The battery that have already been charged with the electricity and can not be used temporary, it also can keep to be in  charge.Don't cut the power of the charger while not  dismantle the battery.
3\While the capacity of the battery is lower than 10AH,please use it according to the usage manual, and be in series connection with a limited electric resistance 2-15 ¦¸, the power is  3-5W.
