Default My battery dies overnight, but comes to life 10 mins later?

These past couple weeks my battery has been dying when i leave for a while. (3+hours) But it doesn't stay dead. After 5-10 mins the car will power on itself, sometimes sooner. When i do turn the engine on, it sounds really bad. When i say bad i mean when you turn the key on a regular car and it doesn't start.

It takes 5-7 secs for the engine to turn on. Everything is reset, but not lost. Navigation memory is still there, but the clock doesn't work, and windows do not roll up automatically.

The most recent thing i've done to the battery is hooking up my HID DRLs to it. I make sure everything is off when i leave the car, but it still happens.

Time for a visit to the stealership?

Get the battery checked. Sometimes bad cells or random cells get bad. Try autozone or similar car part stores to get a free test on it.
