#118981 - 9v batteries Responding to: ???'s previous message |
There are different construction techniques used in making these 9v batteries. I've seen 3 different internal constructions. Some of them could be noisier than the others mechanically, if you abuse them.
Alkalines: Duracell - 6 AAAA, Welded Energizer - 6 AAAA, Compression Ray-O-Vac - 6 Custom rectangular cells, stacked vertically |
