This checks out with me anecdotally, at least. I bought a new car just as the first COVID lockdown let up and right on the forecourt it was complaining about a low battery, apparently due to sitting around for a month or two. "It'll be fine by the time you get it home" they said. Wrong. Even a few hours on a charger and a 300 mile drive only bought me a few weeks of time. I ended up having to trickle charge it for 24 hours to permanently resolve the problem.
- sjg007 5y agoYou probably have an electrical leak. Subaru is notorious for this.
- mint2 5y agoAnecdotal confirmation yes, 3 months out the gate my new Subaru had a drained battery due to a 250mA cold draw while parked that they traced to some random electrical unit and replaced.
- petercooper 5y agoI think so. It was in a Land Rover Defender. Luckily due to the shortages, I sold it after a year for the same I bought it for! :) Sticking to Ford now, too many bad LR experiences.
- sjg007 5y agoLand Rovers probably have the most notorious electrical problems.
- oceanplexian 5y agoFor most battery chemistries, if you drain them low enough the battery will be permanently damaged. Had to explain this to a friend that let their car sit every winter and completely drain the battery and would repeatedly have to buy a new battery every year.
