Are we talking about more or less standard gel cells? The 2V terminal voltage
would seem to indicate so.
Those are *very* standardized, in terms of similar sizes being offered by a
great many different manufacturers. When I was doing the retail battery
thing some years back (roughly 1993-5), we carried PowerSonic and one other
brand I'm not remembering at the moment, and the sizes for similar
capacities was a pretty good match for the Panasonic units listed in the
Digi-Key catalog. Folks would come in with all sorts of other units and I
was usually able to match them up with something that would fit.
I've never seen single cells, but we did have some 4V units which were only
Capacity in any given size of box seems to gradually increase over time. I've
seen 6, 6.5, and 7AH in exactly the same size container, for example.
Shipping is going to be the worst of it. I'd find some national chain
convenient to you (Batteries Plus being an example) and then see if you can
get them to order what you need, and it won't cost you for shipping at all.
Feel free to direct any other battery-related questions my way, if you have
