It sounds as if that battery will do just fine.

Apple have this peculiar idea that their machines need speciallist
salesmen and speciallist maintainers.  The truth is that only PCs need
these!

You will need a fine-bladed screwdriver to ease the cover off and then
the battery just lifts out.  NOTE WHICH WAY ROUND IT GOES.

Drop the new battery in and push the cover back into place.  Put the lid
back in the machine and restart.  It is as simple as that!

Note that if they are not already doing funny things due to low battery
voltage a few settings might get lost when the battery is disconnected.
These include: Date and time; selected desktop pattern; file sharing
on/off; port selection for appletalk; selected startup drive if not main
internal one.
