Led rechargeable lamp, charging is completed, charging indicator light color?
It depends on your desk lamp charging circuit design. If the overcharge protection circuit, the circuit design charging is completed will change color. If charging circuit is pure, not overcharge protection, will not change color. Of course, there are overcharge protection circuit is better than not overcharge protection circuit
What color is your watch before charging, then ran a period of time under observation to know, most of them are will change color. Lattice nita, photoelectric
There are two kinds of lamp battery: Lithium battery charge with mobile phone charge, same instructions filled with red light turns green said, such as no charging indicator can only refer to the instructions. Lead-acid batteries used in dozens of pieces of low-grade called students or children desk lamp, rechargeable light most of the products will not change color, usually from a few hours to ten hours. Lead-acid battery charging requirement after filled with a floating time state, with the changed the user capacity and circuit design is difficult to grasp, because charging time short, filling is too long to form a rechargeable battery life shortened, theonly low-grade products without charging protection circuit, only carefully study the product description. Rough judgment: try every half hour after 2 hours filling light observation (do not charge while light), and if no longer increases should be full of light is the brightest and desk lamp brightness, floating charge time same again can
See what colour before charging, then ran a period of time under observation to know, most of them are will change color. Look at the LED instruction before charging, have on the manual instructions.
