How to charge the camera battery

Abstract: The first thing to do when buying a new DV camera is to take out the rechargeable battery provided by the DV and charge it. How to charge the camera battery? There are also many things that need to be paid attention to when using camera batteries, so that the camera batteries can "extend their life." 1. Charging time of DV camera battery

The charging time of the battery cannot be generalized, because the battery capacity is different, the charging current is different, etc., which will affect the charging time. Digital cameras all come with their own charger. There is a charging status indicator light on the charger. For example, when the battery is first placed for charging, the indicator light will light up. When the battery is charged to a certain level, the indicator light will change color or go out. The battery is basically fully charged at this time, but it will take longer to fully charge the battery. Large-capacity batteries also take a long time to charge. My experience is that if there are two batteries to be charged, charge the smaller one first, then the larger battery. You can go to sleep while charging the larger battery. It will be recharged in the morning.

2. DV camera batteries can be charged at any time

Early cameras generally used nickel batteries. If this kind of battery is charged for too long, the liquid in the battery will crystallize, preventing charging. The device is fully charged. Therefore, it must be fully charged or discharged regularly. Today's digital cameras use lithium batteries. We can charge the batteries at any time at our convenience. There is no need to bother like nickel batteries. There is no need to recharge the lithium battery every time it is fully used and cannot be turned on.

3. The lifespan of DV camera lithium batteries

There are many opinions about the life of lithium batteries. For example, lithium batteries can only be charged 300 to 500 times, and then need to be replaced. The correct statement should be that the life of lithium battery is related to the number of completed charging cycles, and has no direct relationship with the number of charging cycles. A simple understanding of "a charging cycle" refers to the process in which all the battery's power is used from full to empty, and then charged from empty to full. Therefore, the number of times of charging is not equivalent to the actual charging cycle of the battery. For example, a lithium battery can be used for a camera for 10 hours in one charging cycle (note that it is a charging cycle, not a single charge). After actual use for 3 hours, the battery was fully charged; after that, it was used for another 5 hours. It was fully charged again. Although it was charged twice at this time, the total charging time of the battery was only 8 hours for a 10-hour charging cycle. Therefore, the battery was fully charged after 2 hours of use for the third time. It has just completed its first charging cycle.

Just like you are designated to drink a glass of beer. If you drink one-third of the glass and then refill it, it does not mean that you have finished the glass. Regardless of whether the beer in your glass is refilled, you drink it all at once. For one third of a cup, it takes three drinks to complete the designated task, which is "one cycle." Therefore, the correct term for the life of lithium battery should be 300-500 charging cycles.

4. The number of charging times of the lithium battery of the DV camera

In fact, with the above explanation, it is meaningless to talk about the total number of charging times of a battery. However, every time the lithium battery completes one charge Cycle, the total capacity will be reduced a little, the size of the reduction depends on the quality of the battery. Generally, high-quality batteries will still retain 80% of their original power after being charged multiple times. For example, they can reach the upper limit of 500 charging cycles. This is why many lithium batteries are still used as usual after two or three years; those with lower quality The charging cycle of lithium batteries may reach the lower limit at most, such as 300 times or less, so this kind of battery will make people feel that it is more and more "increasingly unusable". In any case, the lithium battery used in DV cameras will eventually need to be replaced when its lifespan reaches its end.

If a high-quality lithium battery has a charging cycle of 500 times, and we charge it every half of the time, it can be charged a total of 1,000 times. Therefore, the life of a lithium battery is related to the total charge capacity of the battery and has nothing to do with the number of charges. The impact on the life of the lithium battery is not much different from recharging the lithium battery after it is discharged or charging as it is used. Therefore, the lithium battery pack used in DV cameras is mainly for convenience. You don’t have to worry about affecting the lifespan of the battery pack when you use it.

5. Precautions for using lithium batteries of DV cameras

First, do not use or charge lithium batteries in an environment above 35°C, and do not store batteries in daily Places where the temperature is too high; secondly, if lithium batteries are used in low-temperature environments such as below 4°C, the battery life will be reduced, and the battery may not be charged in low-temperature environments; thirdly, if lithium batteries are not used frequently, it is best to recharge them every month Complete a charging cycle for the lithium battery, that is, deep discharge and deep charging.

6. DV camera lithium battery cleaning

Many people do not pay much attention to battery cleaning and think it is irrelevant. But in fact, if the contact points at both ends of the battery and the inside of the battery cover are not clean enough, it will easily cause the loss of battery power. Therefore, you should clean the battery and charger frequently. Before using the battery, please use a soft dry cloth to wipe the contact points at both ends of the battery to keep the contact points as clean as possible. When it is found that the electrodes of the battery are oxidized, the oxides need to be carefully wiped off: if severe oxidation and peeling occur, the battery should be replaced with a new one in time.

7. DV camera lithium battery storage

If you leave the battery on the DV for a long time without using it, it may cause battery leakage and damage the DV itself.

Therefore, if you are not going to use the DV for a long period of time, you should remove the battery from the DV, completely discharge it, and store it in a dry, cool place away from ordinary metal objects. Together. To prevent the battery from short-circuiting, store it with a protective cover when not in use. Be especially careful when storing fully charged batteries, especially when placing them in purses, pockets, handbags, or other containers containing metal objects.
