I have a 2010 XC60 3.2. Last night, I hopped in and...nothing. No dash lights, dinging, just completely dead, shifter in P and locked. The only reason I could get in, is because I left the driver's door unlocked, because I need a new key, but it's been working fine that way for over a year. I tried putting my fob into the slot, and it kept popping back out- it wouldn't even go in far enough to catch and stay. I had driven it the day before, with zero issues.
I jumped it, and there was still nothing, even after about 20 minutes. Checked both battery fuses, and they were fine. I was going to take the battery to the shop to have it checked, but can't get it out, because someone didn't put my tools back, and I can't find my 8" 1/4" drive extension- it's bolted to a frame at the bottom.
So, I decided to hook it up to my charger, and the "Bad Battery Error LED" did NOT come on, so I left it on the charger. It's been charging for about 10 hours, and still nothing...
Anyone have this experience or any ideas on what to do? Obviously, taking the battery to get it checked out is my best option, but until I can get it out, I was hoping someone might have some ideas.

 

Sounds like you have a battery with an internal short. Have seen that quite a few times. That problem usually occurs with no warning. Unfortunately usually no consumer quality jumper cables are good enough to start a car with a battery that bad. If you have a battery monitoring system (small wires going from the positive to the negative terminals) it's best to reset that after the new battery is installed. If a size 92-t7 battery is currently installed, it's also best to not replace it with the size 48-h6 battery that fits also. You will get low battery messages if you use a 48-h6 and have a battery monitoring system.
