Battery Applications

An industrial or marine battery perhaps? Automotive is not probable because it is 12 volt in most modern applications. What or where are you getting this?

Fri I presume dc. So you might use it to charge 5 or 6 one-and-half volt rech connected in series

Sounds like what might also be used by mobility scooters.

When I had many questions about batteries for mobility scooters a few years ago, I found this site and the people working their customer service lines to be very informed and informative. See if it helps you.
