Because they are cheap, lithium batteries are more susceptible to damage if overcharged or overdischarged. The circuit must therefore be protected, otherwise they will be destroyed in one go. However, without a protection circuit, nickel-metal hydride batteries can last more than ten to 50 times before failing. Naturally, manufacturers don't like to use lithium batteries. For every yuan added to the cost, the selling price will increase by approximately 7 yuan.
Also, the manufacturer doesn't want your battery to be used 1,000 times. For example, the Panasonic EW-1031 does not have a full-load auto-off feature at all. it gets old after being out of warranty.
Actually, lithium batteries can be used 500 times with different protection circuits.
However, as Chinese incomes increase, high-end electric toothbrushes are equalement sold, which is why some are equipped with built-in lithium batteries. It's the Philips 6 series.
Actually, it's the nickel-metal hydride memory effect that's causing the problems. In fact, it is estimated that the original poster did not charge the battery directly after taking the photo. This effect will prevent power from being recharged into the battery.
It is recommended to use a charger with a discharge function. Although this charger is a little more expensive than other chargers, it will protect the battery.
To eliminate the memory effect and cause insufficient power, you must use this type of charger. It will slowly discharge the internal battery from the unused battery and then charge it.
The author charged and discharged the battery about 3 times. Regarding the discharge process, you can first put the fully charged battery into the camera for use, then put it into thee discharge charger to discharge it after no. more photos can be taken for one cycle.
After doing this about three times, the memory effect of the nickel-metal hydride battery will be virtually eliminated.
In fact, nickel-metal hydride batteries are very durable. As long as the number of charging and discharging times is basically the same as that of lithium batteries, nickel-metal hydride batteries are relatively cheap and economical.
Many people who don't understand say that nickel-metal hydride batteries are not durable because they are not used properly.
It is also recommended that the poster try to use well-known brands of nickel-metal hydride batteries, such as those made in China, Energizer, Speedmaster and Pinsheng. Sanyo Toshiba of Japan. All good.
Although this type of battery can cost a fewyuan more than similar batteries, these brands do not falsely indicate battery capacity and can be charged more often.
The original poster also stated that many rechargeable batteries have false capacity standards. Generally speaking, if the capacity exceeds 2700 mAh, it is suspected that the capacity must be marked, because in terms of current technology, the battery. which can reach 2700mah is almost the limit.
When purchasing a battery, don't overmax the capacity. Excessive capacity will reduce the number of battery charging cycles to some extent.
A professional once bought a Japanese rechargeable battery and used it for more than 5 years. It is still very durable. Its capacity is only 1200 mah.
Finally, I suggest the poster. You shouldn't be too superstitious about lithium batteries. It is incorrect to say that lithium batteriesdon't have a memory effect, it's just the size of the memory effect. That's what the experts say, not me, so even lithium batteries. are the best. Recharge after the battery runs out to increase the number of times the battery can be charged.
In fact, the optimal number of uses for lithium batteries is around 200 times. After that, the battery capacity becomes very low. Additionally, lithium batteries have inconsistent specifications, varied types, and low versatility. Especially when you travel a long distance, you can't use them once they run out of power. Instead, when using labeled batteries, dry batteries can be purchased anywhere in the world. . Temporary replacement.
