This machine uses 2CR5 lithium batteries. These batteries are sold in battery stores in electronic towns or online. They generally cost more than 20 yuan each. Be careful not to buy batteries packaged by Panasonic, as most of them are counterfeit.
A battery of this battery can probably take about 30 rolls. Disposable.
The design of nickel-metal hydride batteries is derived from nickel-cadmium batteries, but great progress has been made in improving the memory effect of nickel-cadmium batteries. The main change is to replace the cadmium initially used in the negative electrode with a hydrogen storage alloy. Therefore, nickel-metal hydride batteries are considered a typical representative of material innovation. The pollution caused by nickel-metal hydride batteries is much less than that of nickel batteries-cadmium containing cadmium. Therefore, nickel-cadmium batteries have been gradually replaced by nickel-metal hydride batteries.
Except for a few lithium batteries that have primary lithium batteries that can be used (NIKON EN-EL1 and 2CR5), most of them do not have battery alternatives. It's very inconvenient for those who want to go there. abroad for a long time or using it in large numbers. Nickel-hydrogen batteries do not have this problem, and digital cameras using nickel-metal hydride batteries can usually be replaced with alkaline batteries.
The battery emits very little radiation when not charging.
It is recommended to stay a little further away from where you sleep. Thank you for your approval.
