BMW 650 won't start up. Changed the battery with an Interstate battery instead of a factory BMW battery and didn't have the mechanic register it. Do you think that's the issue?

The brand of battery doesn't matter, only that it is rated at the proper cranking amps to it will start the car. Fit of the battery (size and shape of the case) are critical too. Make sure the cables are attached to the proper posts and that they are on snugly.

You don't say whether the engine turns over at all, but if it does, the problem is not the battery.

Battery keeps dieing..jump start and runs for a few days and dies

Humm ...Didn't die before the accident? now dies? BMW has good mechanics,but could not find any problem???. I gota think that it is related to the rear ending,but how? I would look for loose connections, Battery Ground that might have been removed before welding.Battery terminals, Any primary connections that may not be making 100% contact . It's worth a try.Good Luck
