I actually do see this all of the time. In decades of owning multiple cars I've found the batteries tend to fail so regularly at about the 5 year mark that you could set a watch to it.
They are easy to find and inexpensive to replace, but they absolutely do have a limited lifespan.
- varelse 5y agoI would love to have found that magical car battery that doesn't die after 5 years or so. But the real comedy is that my EV is required to have one of them independent of all the lithium batteries, and if it discharges/fails, it's a whole fan dance to get into the car.

Can you not get to the 12v battery using a mechanical key? Any 12v jumpstart kit should provide enough voltage to activate the solenoid and get everything online.

- convolvatron 5y agoUnsealed lead batteries that go through proper solution maintenance can definitely last decades - I have a forklift that keeps almost 1/2 its original charge and it was made in 1982. but I have flushed and cleaned the cells a few times and keep track of the pH when I top them off.
