DADNCELL alkaline zinc-manganese dry battery has the characteristics of low self-discharge, which is suitable for household batch procurement storage, and has the discharge performance of continuous discharge time with more long-lasting and large instantaneous discharge. Widely used in flashlights, smart door locks, infrared thermometers, cameras, flash lights, razors, electric toys, instruments, high-power remote control, Bluetooth wireless mouse keyboards and other common household electronic equipment instruments. DADNCELL battery advocates providing a more comfortable and smooth power supply experience for household appliances. The alkaline battery capacity and discharge time of the same model of DADNCELL battery have reached four to seven times that of ordinary batteries, respectively.
The performance difference between the two is greater at high and low temperatures, because its unique internal components are structure and battery materials with better performance, and the power capacity and electrical performance can be improved.
At present, all types of batteries developed by DADNCELL Lab do not involve any heavy metals in production, use and waste. They are green and environmentally friendly and can be treated with domestic waste.
