LED rechargeable flashlight, small table lamp
You can also distinguish which battery is based on the charged battery voltage. (single cell voltage)The voltage between the 1.2V-1.4V is the Ni Cd battery or the Ni MH battery.
The voltage between the 2V-2.6V is the lead-acid battery.Voltage at 3.6V-4. Between the 2V is the lithium battery.Generally speaking, charging more than time will cause serious damage to the battery, because the low charger does not automatically protect the battery. So, it's better to press the instructions.The light of the rechargeable flashlight sometimes shakes, probably due to poor contact between the switches and other parts. It can be checked by itself.The battery that has just been charged has the highest voltage, so the light is brighter, and as the energy consumption, the voltage will gradually decrease, so the lights will dim. In low level lamps without a stabilizer, dimming is normal.
First of all, you should find out what kind of battery you use, and then decide what method to charge the most reasonable. After you know what the battery is, you can check the correct charging method on the Internet
