E70-Replacement battery

Denalio · #1 03-01-2010, 09:49 PM

My battery will only re-charge to 70%. BMWCanada will not cover under warranty. Has anyone replaced the battery with a non-BMW battery? I believe the BMW battery is made by East Penn and is a DEKA AGM battery. Does anyone know? Anyone buy one in Canada?

One person had their battery replaced under warranty got an Exide battery 90AH BMW P/N 61-21-7-553-954. The replacement explanation was "Replaced as per ISID2 Production Error".

getbmwparts.com lists the cost as list price $299 and their price as $239.20. It also says that it is an AGM battery. They don't say who makes it.

AGM is "A newer type of sealed battery uses "Absorbed Glass Mats", or AGM between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. We sell the Concorde (and Lifeline, made by Concorde) AGM batteries. These are also called "starved electrolyte", as the mat is about 95% saturated rather than fully soaked. That also means that they will not leak acid even if broken."

Denalio,
This guy got one from BatteriesPlus (USA)

X5 battery replacement - bimmerfest - BMW Forums

I'd say got to Canadian Tire choose an Eliminator with same CCA (or more) and give it a shot.

No problem with aftermarket. Main thing is to make sure the vent tube is the same. Especially with the aftermarket warranties, save money, ride it hard and then get a new one. Piece of cake.

Just be warned - you will need a trip to the dealer to "code" the car after changing the battery... Otherwise you will get an array of error messages...

The battery number on mine is 61-21-7-551-331 which shows as discontinued and replaced with 61-21-7-553-954 as ChuckG said. I wonder if the original battery had issues?

I just had mine replaced under factory warranty about 2 months ago.

I'll bet that if you connect another battery to the jump start posts under the hood before you disconnect the battery you wold not have this problem. You would have to be careful and insulate the positive battery terminal as soon as you disconnect it. I probably would put a latex glove over it.

As to needing a dlr to "re-code", many of us have reported no problems
after replacing a battery; usually, just turning key on for a minute clears
all the warning lights on dash panel. And, I lost no radio presets.

There are several threads on this, but Search Tab/linking is problematic
currently. I would not worry nor go to the extreme of using a back up
battery, imo.

hey how many of you guys replaced the battery without dealer codings?
Im thinking of using a portable jump starter to hook up in the front to keep voltage going in the system to save memories while unhooking the old battery (original) and replacing with aftermarket. And would I be able to code new battery with SSS?

thanks
