The design of 2500mah nimh battery pack is derived from nickel-cadmium batteries, but there has been great progress in improving the memory effect of nickel-cadmium batteries. The main change is to replace the cadmium used in the negative electrode with a hydrogen storage alloy. Therefore, the nickel-hydrogen battery can be said to be a typical representative of material innovation. The pollution caused by nickel-metal hydride batteries is much smaller than that of nickel-cadmium batteries containing cadmium. Therefore, nickel-cadmium batteries have been gradually replaced by nickel-hydrogen batteries.
NI-MH battery widely used in consumer electronic products and IT gadgets such as Bluetooth,MP3/MP4 player,tablet,GPS,digital camera,Mobile,POS machine,medical facility,GPS,Power bank,solar lamp, Aeromodelling, vacuum cleaner, miner lamp,searchlight, toys, rc models.
