Led emergency light rechargeable batteries often require long-term trickle-charging with low current, because nickel-cadmium batteries have high energy density. It has the advantages of over charging, over discharging, high and low temperature resistance, long life, safety performance and good storage, so it is widely used and has become the preferred battery for fire emergency power supply. Compared with nickel-hydrogen battery and lithium battery, nickel-cadmium battery has more advantages of safety and price competition. As long as the battery is discharged and recharged as far as possible, the performance of the battery will be better.

Press the switch again to turn off the color flickering LED, and then press again to turn on the bright LED. The number is large, so the lighting effect is very good.
Most of the LED light circuits sold in the market are too simple. Although the price is very cheap, it will cause energy waste objectively. Only after some reasonable improvement can it retain its advantages of economy and portability. It also effectively improves the safety and reliability of use. It is suggested to choose Dongjin LED emergency light rechargeable battery.
