Nickel metal hydride batteries are similar to nickel-cadmium cells but have a higher energy density at the same voltage (approx. twice as high). Thanks to their low internal resistance, NiMH batteries can be used in devices with a high power consumption but at a low cost e.g. small LED lights, toys, audio & photography equipment, phones, electric toothbrushes, shavers, power tools and remote-controlled electric models.

Kleiner Akku-große Wirkung. Mit dem Akku laufen Kalender und Uhr meines historischen Computers wieder. Schön, dass ihn noch jemand anbietet.
