Yep, I'd say the battery is probably OK, which means the problem is with the car (or a connection) - something didn't like the low voltage while the car was out of use??
Good Luck Cheers Dave |

I'd still suspect the battery first. It will be interesting to see what Halfords have to say. None of the steps or tests you've conducted so far are definitive when it comes to battery condition. What matters as much as cell voltage off load is voltage at cranking current. It's possible to meet the former and fail the latter, on a battery which is at end of life. And whilst it may still be in warranty, letting lead acid batteries fully discharge and sit like that can, in my experience, be a kiss of death for them.
Another thought is; how are you jump starting? I've also attempted to jump an D5 XC90 with a heavily discharged battery before and hit similar symptoms to yourself. Moving the jump leads from the under bonnet terminals, to directly onto the battery in the boot resolved the issue. I suspect that the former is just a path of too high resistance (corrosion on the bolts, diameter of cable), if a very significant current contribution from the donor vehicle is required.

Halfords have confirmed the battery is good. Specifically, here are the test results:
Rating: 800 EN1 Measured: 726 EN1 Volts: 12.81 V Int. R: 3.41 mOhm Life: 87% Battery: Good I guess the problem lies with the car somewhere. Waiting for the auto electrician/mechanic now cause, I have exhausted little knowledge I have about cars. Thanks everyone for your input so far. Will update once the issue is resolved. |

Time to check all the fuses, looking for power, starting at the big ones
