You need to thoroughly charge your existing battery first before condemning it , that means using and old charger WHICH DOES NOT CUT OFF ... to maintain about 14.8v for at least 24 hours . That should desulphate it and give it a new lease of life ,
(From a volvo service bulletin 5 years ago .)
Assuming you have the 5 cylinder diesel did you have your AUX belt changed at 54000 miles ? ( not time related but MILES )

THAT !
Which means using an old style, traditional charger which is simply a transformer & rectifier which will not cut off and will full saturate the battery over 24-48 hours.
Unfortunately, it's getting very difficult to buy those chargers now. The one I linked to on Amazon was the only one I could find.
