The DV battery of the direction battery has built-in multiple protection function circuits, which have battery overcharge, overdischarge, overcurrent and other protection; except for the DF-248 battery, it has a four-level power display function; the DP-298H also has a B-type port for convenience External equipment such as headlights. Directional battery DV batteries are divided into two categories, one is the battery used for SONY DV cameras, there are the original F970 series DF-248 (capacity 6600mAh), U60 series DF-U65 (capacity 5200mAh) and DF-U95 ( Capacity 6600mAh); One is the battery for Panasonic DV cameras, there are original D54 series DP-266 (capacity 6600mAh), VBD58 series DP-298 (capacity 5800mAh) and DP-298H (capacity 7800mAh).
DV battery charge times
Generally, high-quality DV batteries are used many times and recharged many times, and can reach the upper limit of 500 charging cycles, which will save 80% of the original power. This is why many lithium batteries can still be used as usual after two or three years of use. ; For those of poorer quality lithium batteries, the charging cycle may reach the lower limit at most, so this battery will feel significantly less and less durable.
If the charging cycle of a high-quality lithium battery is 500 times, and then recharge it after it is used, it will be able to charge 1000 times in total, and we will charge it once every half of it, so that it will use the power after the time of charging. Will decrease. Therefore, the recharge of the lithium battery after discharge or the use of the rechargeable charge has little effect on its life. The life of the lithium battery is related to the total charge capacity of the battery, and has nothing to do with the number of charging. After all, the DV battery uses After the time reaches a certain level, it will eventually need to be replaced.
Therefore, the lithium battery pack used in the DV camera is mainly used for convenience, and it does not need to worry about affecting the lifespan when it is used. In fact, with the above explanation, it is meaningless to say the total charge times of a battery. At the same time, you usually have to clean the battery and the charger frequently, especially before using the battery, please wipe the two ends of the battery with a soft dry cloth Contact point, try to keep the contact point clean, so that it can be used longer!
