Why do you prefer NiMH batteries?

Answer 1

There are several advantages of NiMH batteries compared to ordinary alkaline batteries:

1. They can be recharged hundreds of time. So a single NiMH battery can literally replace hundreds of alkaline batteries over its lifetime. This saves money, results in fewer batteries being discarded, and uses fewer resources.

2. The voltage of NiMH batteries is relatively constant with use. The voltage of alkaline batteries decreases as the battery is used. For example a flashlight dims with use when using alkalines. But with NiMH batteries, it will stay bright until the batteries are exhausted.

3. Due to the low internal resistance of NiMH batteries, the voltage does not drop nearly as much under a load as alkaline batteries.

4. Also because of the low internal resistance, the capacity of a NiMH battery does not drop very much under heavy loads. This is why you can typically get many more shots with a digital camera if you use NiMH batteries rather than alkaline batteries.

5. NiMH batteries can deliver a much heavier current. Some devices, such as high power flashlights, cannot run (or cannot run for long) on alkaline batteries (at least on the highest settings). NiMH batteries are required to make the most of these devices.

6. Alkaline batteries may leak when they get old and/or are discharged too quickly. This can destroy whatever device they are used in.

Answer 2

I prefer NiMH batteries because they have a higher energy density, meaning they can last longer between charges compared to other rechargeable batteries. They are also more environmentally friendly as they do not contain toxic chemicals such as lead or cadmium. Lastly, NiMH batteries are more cost-effective in the long run as they can be recharged hundreds of times.
