How to charge a digital camera

Different digital cameras have different charging methods, some are put in the camera to charge, and some are taken out to charge with special chargers.

About charging time

We can be sure that the sentence that the first three charges should be more than 12 hours was completely correct a few years ago, because nickel-hydrogen (cadmium) battery has a memory effect, and its belly is stretched to the maximum in the first three times, so that the battery can know its maximum saturation, thus achieving the effect of long-term use. However, the commonly used lithium-ion battery has no memory effect, so it is completely unnecessary to charge for several hours, which not only wastes electricity, but also has a great impact on the life of the battery itself. Consumers are advised to follow the instructions of the charger, rechargeable battery and camera first. A large number of consumers are too lazy to read the instructions, especially the charging part, which eventually leads to the wrong operation method.

Precautions for batteries

Let's explain in detail the correct charging and discharging methods of lithium-ion batteries:

After a period of time, the lithium battery will enter the dormant state, and the use time will gradually become shorter. However, the activation of lithium battery is very simple, and it only takes 3-6 normal charge and discharge cycles to activate the battery and restore its normal capacity. Regarding the charging time, we suggest that you follow the instructions in the product manual. When the lithium battery is fully charged, it will automatically stop charging, and there is no "trickle" charging of the nickel charger for several hours. Long-term charging will make the charging and discharging protection circuit of the battery wander on the edge of danger for a long time, which will greatly reduce the life of the battery.

Charging is like this. What about discharging? Similarly, the discharge operation should not be carried out excessively. Overdischarge is also a method handed down from nickel batteries, which was originally intended to reduce the memory effect, but it is harmful to lithium-ion batteries. Someone once returned to customer service for repair because the over-discharge voltage of lithium-ion battery was too low. Because of the special design of lithium battery, it is easier to be damaged than nickel battery. Usually it takes a long time to charge, so we have to use the night time to operate, but generally speaking, the voltage at night will be higher than during the day, which is also a potential danger to the delicate lithium-ion battery.

As a conclusion, let's emphasize the correct use of lithium-ion batteries:

① If the battery is not used for a long time, please charge it to about 70% and store it in a dry and cool place. Ni-MH battery will be fully charged again around March; The lithium battery will be recharged around June;

(2) Charge according to the standard time and procedures in the manual, and forget about the first three times. Generally, the lithium battery of card machine can be fully charged within 2-5 hours;

(3) When there is a low battery prompt, start charging as soon as possible, and don't over-discharge;

④ The activation of lithium batteries does not need special methods, and will be activated naturally in normal use.

Finally, I hope that when you use digital devices such as digital cameras, you can play the maximum potential of the battery more efficiently and safely.
