A NiMH battery is a type of rechargeable battery that uses nickel-metal hydride as its main component. These batteries are commonly used in all sorts of devices, from portable electronics like cameras and game controllers to larger tools like power drills.
For example, let's say you're a DIY enthusiast who loves working on projects around the house. You might use a NiMH battery in your cordless power drill, which allows you to move around freely without being tethered to an outlet. When the battery runs low, you can simply remove it from the drill and pop it into a charger to recharge it for the next use.
One advantage of NiMH batteries is that they tend to be more environmentally friendly than disposable batteries. Since you can recharge them over and over again, you're not contributing as much to the waste stream. Plus, they tend to have a longer lifespan than disposable batteries, so you'll save money in the long run.
