sla battery

[rtrg]

Can someone here provide me with a list of vendors of vhs camcorders that all used the same edge contact sla battery in a shell? The SHARP part# is BT21/22, 12volt 2AH. I need the brand names both vendors and retail names and their camera models and their part# for this same battery. Considering how old these are I need to find a third party equal at much less money. I know SEARS and RADIO SHACK and others used this same battery. I also know that AGAIN AND AGAIN, ULTRALAST, EMPIRE, INTERSTATE and DANTONA all have their own versions. They are just as expensive as the SHARP. Which is usually LENMAR. Any help welcome.
