What battery is good for digital cameras?

Kuba helps the assistant answer your question about "". When buying a camera, you must choose a camera that uses lithium-ion batteries. After charging, there is no problem for dozens of days, and it is durable and light. Digital camera is an electronic device with large current discharge, so it is extremely uneconomical to use ordinary batteries. Some cameras can only take a few photos with alkaline batteries, so they have to use rechargeable Ni-MH batteries. Ni-MH battery is also uneconomical and has a short service life. It will not be used because of self-discharge shortly after charging, and it can only be used after charging before using the camera. If your digital camera can only use the No.5 or No.7 battery, then the Ni-MH rechargeable battery is the first choice. Nickel-hydrogen rechargeable batteries can be used repeatedly, so it is expensive to buy flat batteries. When fully charged, the power is strong and durable. And carbon batteries &; Alkaline batteries are useless when they are dead, and a group of batteries will soon run out. At present, most photographers use Ni-MH rechargeable batteries, including batteries with external flashlights. Lithium batteries have higher capacity and longer discharge time than widely used Ni-MH batteries. Compared with Ni-MH battery, Li-ion battery is 30%-40% lighter, but its energy ratio is 60% higher.
