Not had any warning messages yet on the dash - is it fine to carry on until I get them, or at this time of year with the cold and extra load of lights/heaters/etc is it best to get it replaced asap ?
I remember reading somewhere on here before Christmas that Volvo batteries were on special offer, pretty sure it was Clan that posted - anyone know if the offer is still going ?

Having gone through this myself a few years ago essentially what happens is that the battery gets progressively worse until it charges so slowly that even after a 100 mile run it would still be under the stop/start threshold.
Looking on VIDA at the data, the old battery would charge at <2-3A whilst the new one would charge at 20+A initially before dropping as the charge state went up.
It’ll probably last another year or so but one day after not using the car for a few days I barely got it started.
New battery and 2 years/25k miles later still get stop start immediately even after not using the car for a few days.
Long story short: you are ok for another few months but you might as well replace it soon. I got mine from a Volvo Indy for £125 and fitted it myself. Cheaper than everywhere else!
