Hi Mitthrawnuruodo,
Thanks for the reply.
Situation = don't have a serial no., I'm looking into buying a PB - not willing to pay a daft price + it will be used for light duties for a couple of years - currently use a Bondi iMac! Knowing I can free exchange an eligible unit covers me if I can't get the relevant battery details from the seller in time. No free exchange -> possibly need to buy a new battery asap.
Cheers,
OW
