Hello,

IBM changed the AT at least once through it's production run. The one I
have is a later model, since it is an 8mhz system. Yours may differ
somewhat, but I'll tell you what I can see.

I find that same number (#8286121) on my battery. It's actually a
Panansonic replacement battery BR-E3 6v and looks like a small black box
with a cord and plug. It plugs in to the motherboard right behind the
keyboard connector. Mine was held is held in place to the side of the
case with velcro. I'm not sure if the velcro is factory or not.

If your machine has been sitting, unused for sometime, I suspect that
maybe someone took the battery for another use.
