How environmentally friendly are NiMH rechargeable batteries?
Answer. Rechargeable batteries have the greenest environmental credentials. Using rechargeable batteries reduces household waste massively. Globally, 15 billion ordinary batteries are thrown away every year, all of which end up in landfill sites. Rechargeable batteries can be reused again and again which significantly reduces the impact disposable batteries have on the environment. The most ecological rechargeable batteries available are NiMH rechargeable batteries (Nickel Metal Hydride).
