Difference between NiMH and mAH Batteries

Different types of rechargeable batteries are available on the market these days, NiMH and mAH being two such variants. While both have their own advantages and disadvantages, it can be difficult to decide which one to go for. In this blog post, we take a look at the key differences between NiMH and mAH batteries, so that you can make an informed decision when purchasing one.

What is NiMH Battery?

NiMH batteries are a type of rechargeable battery that uses nickel and metal hydride compounds to store electrical energy. NiMH batteries are similar to NiCad batteries, but they have a higher energy density and longer lifespan. NiMH batteries are commonly used in digital cameras, camcorders, and portable electronic devices. NiMH batteries can be recharged many times before they need to be replaced, making them a more environmentally-friendly option than disposable batteries.

What is mAH Battery?

mAH batteries are quite popular these days, especially for people who use a lot of electronic devices. mAH stands for milliamp-hour and it is essentially a unit of measurement that measures the amount of energy that a battery can store. The higher the mAH number, the more energy the battery can store. Most mAH batteries are lithium-ion batteries, which are known for being able to hold a large amount of energy. mAH batteries are often used in electronic devices such as laptops, smartphones, and even electric cars. mAH batteries are also popular because they can be recharged quite easily. If you are looking for a battery that can store a lot of energy, then mAH is definitely the way to go.

Difference between NiMH and mAH Batteries

NiMH and mAH Batteries are two types of batteries that are commonly used in electronic devices. NiMH batteries are NiCad batteries that have been improved by adding a metal hydride to the positive electrode. This increases the capacity of the battery and makes it less likely to suffer from the “memory effect”, where the battery loses its ability to hold a charge if it is not regularly discharged.

mAH batteries, on the other hand, are lithium-ion batteries. They have a higher energy density than NiMH batteries, meaning that they can store more energy in a given volume. However, they are also more expensive and have a shorter lifespan. Ultimately, NiMH and mAH batteries both have their own advantages and disadvantages, and the best type of battery for a particular application will depend on the specific needs of the user.


NiMH and mAH batteries are two different types of rechargeable batteries. The main difference between the two is that NiMH batteries have a higher capacity than mAH batteries. For this reason, if you need a battery with a high capacity, you should choose a NiMH battery. If you need a battery for devices that require low power consumption, such as watches or hearing aids, an mAH battery would be a better choice.
