About Nickel-Metal Hydride Batteries
A nickel-metal hydride battery, abbreviated NiMH, is a type of rechargeable battery similar to a nickel-cadmium (NiCd) battery but using a hydrogen-absorbing alloy for the negative electrode instead of cadmium. As in NiCd batteries, the positive electrode is nickel oxyhydroxide (NiOOH). A NiMH battery can have two to three times the capacity of an equivalent size NiCd.
We use only high quality NiMH batteries in our commercial rechargeable tealights.
NiMH batteries are considered to have lower environmental impact than NiCd batteries, due to absence of toxic cadmium.
