No, it is important to use a charger specifically designed for NiMH batteries to prevent damage and prolong their life.

NiMH batteries can be considered to be an environmentally friendly battery because they contain fewer toxic metals than NiCad batteries. However, it is important to recycle them properly.

NiMH batteries have a higher self-discharge rate than some other battery types, meaning they lose their charge even when not in use. This can be reduced by storing them correctly and using them regularly.

NiMH batteries are best stored in a cool, dry environment and preferably partially charged. This minimises self-discharge and extends their life.

Yes, NiMH batteries can be fast-charged, but this can shorten their lifespan. It is better to opt for slow charging to preserve capacity and lifespan.

To charge NiMH batteries correctly, it is essential to use a charger specifically designed for NiMH batteries to avoid over- or undercharging. In addition, it is recommended to charge slowly to avoid overheating and damage.

NiMH batteries have several advantages. They have a higher energy density than NiCad batteries, are not prone to memory effect and contain fewer harmful metals, making them more environmentally friendly.

NiMH-batteries (Nickel Metal Hydride batteries) are a type of rechargeable battery that is widely used in different kinds of electronic devices. They are an improved version of the NiCd-batteries (Nickel Cadmium batteries), because they contain fewer heavy metals, making them more environmentally friendly. They also can store more energy and are less susceptible to a memory effect. This makes them very easy to maintain.

It can be possible in some instances to revive an old NiMH-battery at your own risk, but the success rate may vary depending on the current condition of the battery. If there is any physical damage like corrosion, bulging or leaks, it may not be safe to revive it.

Sometimes charging the battery can help. When the NiMH battery has been discharged for a long time and is completely empty, it might enter a deep discharge state. In some cases, cycling the battery might be the answer, by fully charging and discharging several times.

Some NiMH battery chargers, also known as a smart charger, come with a reconditioning or trickle charge feature. This applies a low current to the battery for a longer period, which can revive batteries that have been deeply discharged.

An empty NiMH-battery will have a low voltage. You can verify this by using a voltmeter. If the battery has 0V, it cannot be charged in a with a smart charger.

However, a NiMH-battery can be revived by using cables and another fully charged one. Connect one of the cables from positive of the fully charged battery to the positive of the empty battery. Keep them connected for three seconds and then disconnect them.

With the voltmeter you can see if the empty battery has now some voltage in it. Now you can put it in a smart charger again and it will start charging.

In most cases, NiMH-batteries (Nickel Metal Hydride batteries) and lithium-ion batteries aren’t interchangeable. They have different shapes, sizes and voltages most of the time. Sometimes a device can accept both, but this will most likely be mentioned on the product or in the manual.
