Help me make a decision about the type of battery for my digital camera. I want to buy it.

In fact, the use of batteries is not so strict. I personally recommend lithium batteries, but this is not absolute. In fact, the Canon A series uses AA batteries (AA batteries), which are also good ( It is best to use high-power ones (such as 2400 mAh)

Ni-MH batteries generally need to be charged for the first time. They must be fully charged, but not too long. Generally, 15-18 hours is better. Try to Charge after the power is used up. Although nickel-metal hydride batteries have no obvious memory effect, it is still recommended to charge when the battery is not working (discharging). In addition, do not charge for too long in the future. Pay special attention to The quality of the charger, otherwise it will seriously damage the life of the battery. There are many fake nickel-metal hydride batteries, so you should pay special attention when buying them. Currently, Pinsheng and Speedmaster are better brands. It is recommended to start with these two brands. The battery capacity is 2400 millimeter. The best is about 2800 mAh. Some of them are not technically convincing, especially compared to their price.

Lithium batteries are very delicate. You need to pay attention when using lithium batteries. , Lithium batteries are different from AA rechargeable batteries. Generally speaking:

When lithium batteries are charged, they will terminate when predetermined conditions are met. It is meaningless to continue. If you encounter a poor-quality charger, it will even Exploded and caught fire due to overcharging!

Therefore, some instructions say that the first few charges must be fully charged for 12 hours in order to fully activate the battery. This is actually inherited from the usage of nickel-metal hydride batteries. The activation of lithium batteries is achieved by fully charging and discharging cycles in the first few times, rather than by charging time.

Secondly, lithium batteries have no obvious memory effect. In principle, they can be charged at any time. No need to wait for the battery to run out before recharging it. Excessive discharge can also damage the battery and cause capacity reduction. Most equipment using lithium batteries has a low-voltage alarm function. Once the alarm starts, it means that the discharge cutoff threshold is about to be reached. At this time, you should stop using it immediately, replace the battery or start charging.

Generally speaking, the life of a lithium battery is 500 times, which actually refers to the number of complete charge and discharge cycles (2.75V~4.25V). Not the actual number of uses. Even if it is fully charged and discharged once a day, it can be used for at least one and a half years. Therefore, you can use it with confidence.

Thirdly, lithium batteries are relatively sensitive to temperature. At low temperatures, their effective capacity will drop rapidly, giving the impression that they are not durable. Therefore, when using it outdoors in winter, it is best to store the spare battery close to your body. If the battery used at this time is kept close to the body for a while, it may recover a little power and can be used in emergencies.

Fourth, lithium batteries, whether lithium polymer batteries or lithium ion batteries, may be in danger of fire or explosion if used improperly. Therefore, short circuits, violent collisions, punctures by sharp objects, etc. must be strictly avoided.

Once expansion, heating, pungent odor, etc. are discovered, the battery should be placed in an open place immediately, and pay attention to fire prevention, and do not touch it directly with your hands.

Therefore, there is no need to worry about the battery. When weighing the choice of camera, just choose a battery that is suitable for the product. If recommended, it is a lithium battery. Compared with digital products, it consumes a lot of power. A lithium battery can ensure that the machine works longer.
