In a nutshell

The AA-size accumulators are the most common and are those on which, with those at AAA standard, manufacturers have made tremendous progress in terms of cycles and capacity, while maintaining relatively low costs, so that further than being in tune with the ecological time, they are economic in medium and long term. Sold in 4, these 1,5V Ni-MH accumulators, are used notably in RF transmitters, but also in field mixers, and some miniature recorders such as Zoom, Sonosax, Tascam.

Sold by blister of 4 units.
