They probably have to connect PIWIS anyway. It's trivial to get the battery health. Any problems found on diagnostics (battery or otherwise) leads to more $ for the service dept.Why do you think that? Maybe I am too cynical, but I bet he turned the key and the car started.
Yes, probably SOH but most of us do not have PIWIS!Take a look at this from PIWIS (start at about 13 min). Not 100% sure it's SOH (vs SOC or something else), but clearly the computer keeps tracking of battery health in some way and this is obviously what the dealer is using to evaluate your battery. I suspect 3rd party tools can access this info as well, but haven't tried myself.
jzwu, Can you tell me how to get to the display of battery condition?No I haven’t taken a voltage measurement of my OEM battery. So far everything seems good. No problem starting the car at the first crank and all electronics works fine too.
The charging voltage on the display is 14.9v now, which I assume it’s due to the ambient cold temperature (50’s). In summer it’s 14.4v.
This has been discussed/debated. Some of us do not believe that reading is a true indication of battery voltage.if you stop one click short of actual ignition when turning the “key” to start up the battery gauge will be showing battery voltage as the alternator isn’t running until the engine turns over
Mostly true, but a minor fly in the ointment is that the dash lights -- and who knows what else -- will be drawing some current at the time. Ok, minor, but seems just a little more accurate to just put a volt meter on the terminals. (I have a box of 20 or so of the VOMs, as Harbor Freight used to give them away with coupons.)if you stop one click short of actual ignition when turning the “key” to start up the battery gauge will be showing battery voltage as the alternator isn’t running until the engine turns over
