Aren't the spade connectors on APC batteries a different size to "standard"
batteries to encourage punters to buy the APC branded replacements?

They're larger, but nothing that wasn't solvable by closing
up the female connector a bit with a pair of pliers.

Other issues are that you probably won't be able to reset the
battery change date, and that you must do a recalibration run
after a full charge, or the UPS won't know the battery capacity
has increased (if it's one of their more intelligent models).
