Collection of DC rechargeable batteries

Recently, many people and friends are very concerned about the issue of rechargeable batteries for their favorite phones. There are a wide variety of brand models on the market, which is really confusing. Let's summarize this confusion with everyone and discuss the performance of the batteries currently used in digital cameras, how to tap the potential of the batteries, and finally talk about how to maintain and let you go out. I was even more aware when shooting. In addition: Many cameras, such as Sony series, and some pocket-sized machines (supplied with a simple charger), use a lot of expensive batteries than general AA Ni-MH rechargeable batteries. The quality is good, and the battery life is strong. People rest assured. There are many brands of AA rechargeable batteries used in most digital cameras, but there are big differences in quality when they are used. We will discuss with you the most popular cheap and high-quality AA rechargeable batteries: The batteries commonly used in digital cameras are divided into lithium batteries, nickel-metal hydride batteries, nickel-chromium batteries, alkaline batteries, etc., the most popular and also the most mature technology of nickel Hydrogen batteries are deeply loved by everyone. The advantage of NiMH batteries: The discharge curve is very smooth, and the voltage will drop suddenly when the power is almost exhausted. Ni-MH uses nickel hydroxide as the positive electrode and high-energy hydrogen storage alloy as the negative electrode. Therefore, the positive electrode of the nickel-hydrogen battery is basically the same as the nickel-cadmium battery, but the negative electrode uses high-energy hydrogen storage alloy materials, which makes the nickel-hydrogen battery have greater energy. At the same time, the electrochemical characteristics of nickel-metal hydride batteries are basically similar to those of nickel-cadmium batteries, so nickel-metal hydride batteries can completely replace nickel-cadmium batteries when in use, without any modification to the equipment. And the battery does not contain mercury, which is very conducive to environmental protection, and the memory effect is slight.
