home battery pack How to Extend the Life of a Nickel-Metal Hydride (NiMH) battery?

NiMH or nickel metal hydrogen batteries have improved compared to older NiCd or nickel-cadmium batteries.The problem with the nickel-cadmium battery is that it is affected by the so-called memory effect or so-called voltage suppression.This is really a memory effect, but the voltage drop caused by the formation of crystals inside the battery.
These crystals form when the battery is fully charged.NiMH batteries are less vulnerable to these problems, but they are still affected by them.To prevent this and other problems, extend your battery life, please try the following: cycle charging.
Cycle charging means fully discharging the battery and then fully charging.When you turn on a new set of batteries, you should cycle to charge them at least 3 times to achieve its maximum performance.Also, charge the NiMH battery at least once every two weeks.
This prevents the formation of crystals.
Inside the cell.
Do not mix with other cells.
Do not mix NiMH batteries with alkaline batteries and lithium batteries.They behave differently and may have adverse effects on cells.Also, do not mix the battery pack.Do not mix the battery from one package to another.
The battery pack is paired during manufacturing.Devices with the same internal resistance and voltage output are paired in one package.This prevents one cell from damaging the other during use.
When the batteries of different battery packs are used together, the battery with the weakest voltage output will degrade faster than other batteries.Prevents reverse polarity.I mean two things, the first is never to put the battery in the wrong polarity, and the other is to prevent the battery from being in the opposite state of polarity.The reverse polarity will inevitably damage the battery.
Modern electronic devices have safety features that automatically turn off the device when the battery is below 0.9 volts.However, simple devices like flash and radio do not have this feature.When the device shows that the battery is low, stop using them and remove the battery from the device.
Stores in a state of discharge.
If you are not going to use your batteries for a long time, discharge them and store them in a cool and dry place.Each cell has a different self.discharge rate.While the difference between them is small, this can cause uneven battery packs.What will happen is that the battery will be self-discharged and one battery will charge more than the other.
When you use them, the other battery loses the charge faster, so even if the other battery still has the charge, the device you use it will stop working earlier.When you charge the battery, one will reach full charge before the other and will be overcharged.As mentioned earlier, overcharging can damage the NiMH battery.
