Battery Replacement

Looks like its time to get a new battery after 6 years :/ (Discharge Warning) The dealer quoted over 500$ total and I've been searching the forums for some form of DIY for this and have mixed info. So I've been searching for a battery and found a Duracell

I guess my question is does this battery meet the OEM specs. And also I heard that the bmwlogger tool is good for battery registration but a good OBD 2 cable is needed to work. Anyone have any ideas? Much thanks for any input.

Yes, it will drop in as a replacement and meet OEM specs (this battery is 92 AH and 850 cold cranking amps, AGM construction). Sears Diehard Gold Group Size 49 is a good one also.

Some BMW indie shops will register a battery for almost nothing if you drive in with a new battery and look like you could potentially be a good customer ; ). I used the Carly for BMW (formerly BMWhat) but you do have to buy a wireless OBD dongle from them and have a suitable smart phone.

Thanks for the input. I didnt know the BMWhat app could register the battery. I have and used it with my bt dongle before to enable some keyfob options. I will check into it. Thanks again.

Put a trickle charger on it over night. I saved mine doing just that, and it's lasted another 2.5 years since then.

I will still get the warning every 4-8 months I'd say, at which point I charge it overnight again and I'm good again.

The charging system in our cars is whack, and it doesn't do the best for the battery on short drives.

Subscribing...surprisingly still on the original battery on my 08. Should be only a matter of time until I am in the same boat.

+1. Try a trickle charger first. I'm going on over 2+ years with no problems on a battery that I thought was long gone. To keep it fresh, every few months I hook up the trickle charger and let it charge for a couple of days. It's not my DD so buying a new battery didn't make sense because even a new battery would need a trickle charger if it sits for too long.

It's a $10 in app purchase but worth it.

I've started a couple posts about battery replacement. BMWlogger + DCAN cable will work fine. If the BMWhat app can do it, then go that route if you already have it. I personally have the DCAN cable b/c if you ever have to load a tune/have anything retrofitted, if you have your own DCAN cable (which is required for both, btw) you don't have to pay the vendor for one.

Anybody have comments to share regarding the light weight battery options. Would love to shed 40-50 lbs this way.
