TR: Battery

["Rick Taylor" <rgt3000@one.net>]

Well, my circa 1981 battery has finally given up the charge.  I need to
replace this and remember a thread about batteries a short while ago but
didn't save it since mine was fine then.  What is the consensus for the best
type for my 4A?  I thought someone was talking about a "dry" battery.  My
shelf is not rusted or corroded and I would like to keep it that way.
Please advise.
