A battery running flat once isn’t such a huge deal. Running flat repeatedly or running so low it can no longer be charged back up is, but it’s still fairly uncommon to happen unless the battery is already dying.
I ran my battery flat like 10 times in a week testing my OBD2 app since I was mostly testing it at night and didn’t want to start the engine and it’s a 2007 Audi so the ignition-on power consumption is ridiculous (must be dozens of amps). Still no issues. My other car has manually switched lights which I forgot to turn off the other day and came back to an extremely dim sidemarker being the only thing still lit up in the morning, this one is a 2001 so it’s not smart enough to turn off consumers, it ran flat and kept on powering that light. Started it with my booster and after a few kilometers driven, it started without the booster again. This one isn’t even a particularly new battery, at least the other one is a 3-4 year old Exide.
My message was meant for people who do not take these things into account. As there are many of them.
Also, you can definitely permanently damage your battery by letting it discharge too far. This is due to a process called hard sulfation.
It’s 5 weeks, it’s not a long time. You need to take these things into account when it’s multiple months.
Depends on your model. Some BMW, Volvo, VW and older Teslas discharge within weeks. Mostly due to their built in telematic systems and luxury systems.
Yes, and then you charge it.
