I performed a search on this topic and got several irrelevant topics.

I need a new battery for my 2005 545 and I'm checking to see whats available and what others have used. I obviously prefer not to go to the dealer. I read some posts regarding different battery brands in the past but, cannot seem to find them.

Any help would be much appreciated!

 

I have been looking myself:

I recently changed out my 530i battery for Gold-Duralast/Battery (95R-DLG) | | AutoZone.com;

 

Yep, I've used AutoZone Duralast on my BMWs of past and will continue to do so.

Personally I wouldn't use Autozone batteries. I've used them on my other cars and they never lasted more than 2.5 years. I have just been doing their warranty and prorate deal everytime their Duralast batteries screwed me. Now with the BMW battery registration, it would be an additional cost each time the Duralast doesn't last.

 

Hey boss, I'm in LA also. I'm looking into getting the OEM battery and getting it registered. Would you know a spot in LA or OC?

 

I have a Duralast and did not bother with registration. Personally, I believe it is a waste of money and if you do the math, any reduction in battery life is easily offset by using less expensive non-BMW batteries and the cost saved in not registering them. Search the forums. I don't think anyone who has not registered has experienced a problem.

 

I have searched the forums. Some claim that their unregistered battery didn't last to make it to 2 years. I also searched and started threads asking if anybody has been on an unregistered battery for 2 years or more and no one has claimed that. (of course it doesn't mean it's possible).

Right now my OEM battery is still going strong and it's been just over 5 years old. I'll gladly pay for that piece of mind and reliability. To add to that, I plan on getting the BT scan tool anyway so that I can do my own diagnostics and battery registration.

 

got my battery from batteries plus. Werker 95R. Been over a year.

Walmart $67
3 yr warranty
Been using them for years on 5 different BMWs...Manufactured by Johnson Controls.
Get a new one before 3 yrs, then perhaps you'll get 6 yrs for $10 a year you can't beat that. More powerful all around than OEM battery.
