Default Re: Amazing D cell discovery!

I note that a comment in the link given in post #42 by someone who was involved in the submarine project, mentions that they had had problems with "a certain popular make", but does not say which one.

We're careful about which batteries we buy

I work on the Autosub project.

We make sure that we buy batteries that don't need to be whacked to make them work! We were actually bitten by this problem a few years ago and since then have steered well clear of a certain popular make of manganese alkaline cells.

We also have a novel packaging design for lithium polymer cells which we use in our deep diving Autosub6000 vehicle.
