Batteries for e90/92

[Mezmhn]

Hi,I've heard that the batteries cost a bomb to replace and you need to reconfigure the obc again. Can we use normal car batteries ? What's so special with BMW batteries ?

I just changed mine to this brand Century Marathoner.

BMW OEM batteries are longer lasting... maybe 4 - 5 yrs but costs 2-3x of regular batteries. I just changed to AC Delco battery after 4 yrs because my car's battery died at home and I just called nearby autoshop for quick replacement. Price was about RM500 but dunno how long it lasts yet. No prob with OBC as long as you ensure engine running or use spare battery to ensure uninterrupted power supply during battery replacement.

Cheers

You need to get to a diagnostic OBD to tell the car you have change the battery, to prevent over/under charging. E9x has a smart charging system that needs to know if you have replaced the battery, just google exploding batteries on e9x if you dont believe me

You certainly need to register the new battery, especially change to other type or different capacity (Ah) battery.

Here's my experience.

The ori battery for my e92(Cbu by AB) lasted about 2.5 yrs. then it went dead at home. So i called AAM to replace with their own maintenance free battery. Cost rm460. Then, after about 1.25 yrs (3 wks ago ), i smelt something funny inside my car. After further inspection, i found that the battery has leaked the acid. I called them again to replace with same battery...too bad the the warranty period was gone. So i paid for another rm460. One thing i noticed, after the old battery was removed, it was still hot. Not taking any chances, i send my car to AB to check possibility of wiring problem etc. lucky nothing. Have to re-program.

Anyway, it is recommended to re-program after u replace battery.

Battery from bmw cost rm1200-1800 but lasted 4-5 yrs. my previous car lasted 4 yrs.

are we able to re-program on our own if we replace outside?

To my best knowledge BMW batt are only available from BMW authorized service centers or from new cars. If you can get it cheap it might be refurbished battery. Sorry bro
