While at my local (85 miles away) Radio Shack outlet store, in
search of the elusive DSP, I found two 4AH 12V batteries. Not
knowing if it was a deal or not, I got them. Don't see many of them
around these hinterlands, particularly surplus.
Anyway, if I connect these batteries in parallel, I'll get 12V, and
*should* get close to an 8AH rating for the pair -- correct?
Question is: Would the charge rate for these batteries need to be
adjusted if they were left in parallel? Each battery is charged
(according to the label on the front) at 1.2 Amps max -- no problem.
But two amps? That would probably be a problem.
I'm considering building a charger from my trusty, rusty (and after
9 months in a rented storage room, musty!) 1990 Handbook.
Supposedly it cuts back to a "maintenance" mode automatically upon
achieving full charge.
The plan would be to leave them charged, and take them on weekend
trips (I think 8AH would get me through a weekend of QRP operating).
Might use them at home some, but not much -- will probably use the
12V supply I already have for home use.
Thoughts? Comments? Would I be better off to use them as separate
4AH batteries and charge them independently, and avoid all this?
