My guess, battery was flattened leaving doors open and stuff on while doing the work, probably on way out anyway. He’s charged it and all working, may or may not come back to tell us…. Also easy to get caught out using a basic meter to check a battery.. Wife’s gave up on her Astra in this most recent cold snap, fine one day and click click the next. But with a dvm it shows 13v- until you put any load at all on it and it dives for 9v! Needs a proper check to confirm. Yes, we are "enjoying" the right sort of conditions here right now for the usual flurry of battery-related problems - loads of snow, long-term cold snap, cars just being used for local journeys because people cannot get out of the glen......that sort of thing.
I would have thought that using the MB battery-management data on the dashboard would be a fair indication of the condition of the battery - certainly more accurate than a snapshot measure with a DVM. These days, I no longer trust the terminal voltage alone to make "the call" on a battery; a decent battery-condition measurement is made most of the time with the Picoscope, but sometimes I'll just go on gut instinct when I turn the key, if I know how and when the battery was last charged off the vehicle.
It's f***ing cold outside right now - I don't blame any battery that wants to stay in bed!

Volvo & Merc. diagnostics have quite in-depth electrical analysis functions (if only LR did!) and can give accurate battery usage and SoH / SoC measurements - much better than the Midtronic tests.

What are you saying here...... ? Are you suggesting that LR electrical analysis is anything but a simple task, or that the onboard systems have not been refined to within a micron of the gospel-truth
I have always found the depth of LR analysis absolutely spot-on......It's deep, it's sticky, and it's brown. The problem lies directly between the front and rear bumpers. The only fault-code you need is the green oval badge.

I used to think it was a rose-tinted illusion that "people struggled-through better in the old-days", but when you analyze it in the cold light of day, cars were a lot better when all you needed was a little bit of battery to keep the coil alive, and the rest was mechanical simplicity and reliability. Gold, old-fashioned SU carburetors and fuel-pump, married to a solid B-series.....

I had a 1964 MG Midget in the '80s, I bought it as a 'kit', rebuilt it and chased fanny (not her real name!) around the country, one night I was driving down the old A38 beyond Exeter to Newton Abbot, the hill rose into a snowstorm, this was early-O'clock in the morning by now and the car kept cutting out due to the driving snow melting on the ignition leads and distributor cap, I'd nearly run out of Duck Oil so, given the lack of other traffic, there was nothing else for it. Stopped, did a three point turn and continued in reverse, with only the door mirror, protected by having the quarter-light open and as a way of wiping it every minute or so, I made 'progress'. The only other car I saw was a police car on the other side, who gave me a cheery wave as I went past... in reverse.

I wonder if he has charged the Merc battery up bu now? 😆
