This means that your battery life is nearing and your battery performance has dropped significantly.
There are three possible scenarios:
1. Your battery has indeed been used for a long time.
2. Your battery has only been bought for a long time.
3. Your battery has been used for a few months, and suddenly that's it.
The first kind of thing is that the battery life of the slippery ant is really up, so change the battery.
The second situation is basically because of buying counterfeit and shoddy batteries, this kind of batteries are mostly repackaged with waste nickel-metal hydride batteries and then taken out to sell manuscripts, or the factory testing failed the batch, this kind of battery is basically unusable, if you can provide the brand of the battery, then you can better judge.
The third possibility is that your battery has been over-discharged, resulting in damage to the cathode structure, which reduces the performance of the battery, or you have bought products from domestic defective manufacturers, and the life span is exhausted after charging and discharging more than ten times.

Hello: NiMH battery: the nominal voltage is, the full charge voltage, the cut-off voltage is 1V, and the voltage after discharge is less than 1V, which is overdischarge; It is characterized by high capacity and insufficient power, and nickel-metal hydride batteries now also have multiplier type power batteries, and the capacity is reduced compared with ordinary ones, but the discharge performance of large batteries is better.
Nickel-cadmium battery: the nominal voltage is, the highest full voltage can be reached, the cut-off voltage is 1V, and the voltage after discharge is less than 1V, which is over-discharged, which is characterized by much lower capacity than NiMH, but has better power performance and is suitable for use under high-current conditions.
Alkaline battery: nominal voltage, no-load voltage, cut-off voltage, and then discharge is overdischarge.
Manganese batteries have a wide range: carbon zinc-manganese, alkaline zinc-manganese, and lithium-manganese batteries;
Carbon zinc-manganese battery: It is an ordinary carbon battery, the voltage is similar to alkaline, but the capacity is very small, and it is generally only suitable for remote control, clocks and other use environments;
Alkaline zinc-manganese battery: it is the alkaline battery in front;
Lithium-manganese battery: It is a disposable lithium battery with a nominal voltage of 3V. No-load voltage.

NiMH battery is a kind of rechargeable battery, and now the No. 5 and No. 7 rechargeable batteries on the market are mostly nickel-metal hydride batteries, and they are nickel-cadmium batteries for a period of time, and now they are replaced by nickel-metal hydride batteries with larger capacity.
Not all of them are rechargeable batteries for cameras.
There are many varieties of cameras, and the corresponding batteries produced by different manufacturers are different.
Some cameras can use regular AA batteries, which are size 5 batteries. Of course, you can also use No. 5 nickel-metal hydride batteries to replace, the advantage of using this battery is that it is highly versatile, in case you want to shoot more, when the camera is out of power, you can go to any small store to buy an ordinary No. 5 dry battery to replace.
Some cameras use lithium batteries, lithium batteries are also a kind of rechargeable batteries, generally used in mobile phones are this kind of lithium batteries, lithium batteries are generally special batteries, there is no difference between No. 5 and No. 7, they are special electrical appliances with special batteries. The advantage of this type of battery is that the rechargeable battery is much faster than the nickel-metal hydride battery, and the voltage is also higher, which is also very suitable for some specialized equipment.
The disadvantage is, of course, poor versatility, because the battery and the device are one-to-one correspondence, so once the battery is damaged, it is very inconvenient to buy.
Nanfu 5 yuan a pair of batteries is not a charging battery, but an alkaline dry battery with a large capacity. He thinks that the benefits of other dry batteries are that the stored electrical energy is much higher, the use time is long, and the chemical composition of the battery is alkaline, once damaged, it will cause less environmental pollution.
But this kind of battery is also a disposable battery that cannot be charged.
From the **, the dry battery No. 5 is about yuan, while the punch-shaped No. 5 battery is.
It is about 10 yuan, and the imported goods are more than 15 yuan.

NiMH batteries are rechargeable batteries that can be recharged and used repeatedly.
An alkaline battery is a disposable battery that is not rechargeable.
Nanfu 5 yuan pair of batteries is alkaline batteries. Can be used with a camera. 50-80 shots can be taken. Shoot often, this kind of battery is too expensive and not cost-effective. It is better to buy a rechargeable battery for more shooting time.

The charger for AA nickel-metal hydride battery cannot charge AA lithium battery. The nominal voltage of an AA NiMH battery is about when it is fully charged.
AA lithium battery is divided into lithium cobalt oxide and lithium iron phosphate, and the nominal voltage of the former is. The latter nominal voltage is. When fully charged, the voltage is.
Only the latter can be used on digital cameras. However, because the digital camera uses two nickel-metal hydride sections, the lithium battery can only be used on one section, with a placeholder cylinder that only plays a conductive role, otherwise the camera will be burned out with two sections. Lithium iron phosphate AA battery to buy a special charger, in addition, the maximum capacity of AA lithium iron phosphate battery can only be 600mAh, it is impossible to reach 2700mAh, **you can go up** on the search for the next generation of lithium iron phosphate AA battery.

It should be the same size as the No. 5 battery. I have dismantled it, and no protective plate was found, and the short circuit either burned the wire or discharged light.
-
NiMH batteries do not require protection plates.
It is 0v before charging, indicating that this battery may have the following reasons:
1: The battery has been in the electrical appliance for a long time, in the state of over-discharge, the voltage will be 0V, after several charging and discharging cycles, the voltage will return to normal, charging state, discharge state.
2: There is a slight short inside the battery, the voltage is 0, and it will rise temporarily after charging, but after a period of time, the voltage is 0V or lower than 1V again, which is actually a bad battery.
-
From 0V to near full charge, it means that the life of the battery is at the end of its life, and it is no longer able to store a lot of charge inside. The role of a battery is nothing more than to store an electric charge, and a battery that does not have the ability to store an electric charge is definitely a waste battery.
NiMH batteries are safety batteries, and there is no danger of short circuit and overvoltage, so no additional protection circuits should be added to the use of NiMH batteries. However, the voltage of nickel-metal hydride batteries is low and rated, so the overall energy density is low, and the volume will be relatively large.
On the other hand, nickel-metal hydride batteries also have the advantage of being a direct alternative to alkaline batteries, which is a good choice for mobile devices that require low energy density, low discharge current, and rechargeable reusable mobile devices.
Store again after a full charge. When you take it out in the future, it is best to charge and release it several times before the capacity can be restored. You can buy the kind of charger with automatic point function.
Friend, I have been engaged in nickel-metal hydride rechargeable batteries for photography for many years, I know this very well, according to the parameters you provided, I helped you calculate, your battery after the first use of photoelectricity, one-time four synchronous charging, it is best to charge 25-30 hours, that is, 5 to 10 hours more, not more than 30 hours, so as not to overcharge, damage to the battery, but your charger for your battery, belongs to slow charging, more hours, less hours, generally does not matter, do not worry too much。 >>>More
NiMH batteries have a memory effect.
If you use a universal charger, it is very likely that the battery has not been fully charged before, so no matter what charger you use in the future, even if the display is full, but in fact your battery has not been fully charged, so the battery you said will not last long and there is no power! >>>More
It depends on what kind of charger!! If you have a fast charger, it will be enough for about 5 hours, oh!! But this one doesn't have an automatic stop charging function!! >>>More
