Free drop test
It has been freely dropped to the smooth concrete surface from a height of 1 meter with zero initial speed for two times without disfunction，deformation, or braking apart..

Frontal flat crush test
Contact wholly and flatly crushed every sides of the charger with a 25kg vertical force for 10 seconds, and it should be normal after three crush tests.

Flip-open cover age tests
Turn over the cover of the charger at a speed of 25-30/min (Come-and-go is considered as one time) with maximum turned position. It should be normal after at least 10 thousand tests.

Product properties:
1. It has intelligent microcomputer control system with high accuracy prolonging the age of batteries；
2. It has independent four channels and four charging loops, and can be charged singly with one battery;
3. It is applicable for 1-4 ”AA” or “AAA” Ni-H/Ni-Cd rechargeable batteries；
4. 2 Channels Minus Delta Voltage;
5．It can recognise the irrechargeable batteries, inferior batteries or discarded batteries automatically；
6．It has four double-colored LED indicator, the red light indicates charging state while the green light indicates charged state.

and the charging state can be deleted.（我是这样理解你的“清楚”的，就是让充电的状态不显示在屏幕上，不知道对不对？）

7．Transfer to trickle charge mode automatically after charged preventing power loss；
8. It can be supplied with external sources（adapter, car charger or computer USB socket）；
9. It has the safe-keeping devices preventing over loading, short circuit, and over heating.;
