Everstart Maxx (walmart) 94R exceeds BMW spec
 

I googled my way to the Everstart Customer Service number ( 1-888-387-8278 )for Walmart employees and decided to try my luck. I used my store number (2252) and pretended I had a customer who wanted the specs.

The 94R has a reserve capacity of 155 mins and amp hour rating of 85aH. Its a 950 CA and 850 CCA battery.

The stock BMW 94R battery is rated at 140 mins RC and 80aH with 720CC and 720CCA.

Also comes with a 3YR free replacement warranty.

I picked mine up for $82 + $9 core.

I just recently popped it in and it fit perfect. Had the vent tubes and all. Just had to punch the side I was using.

I purchase that battery one year ago today after a month and a half without using my X5 I had to call AAA to jump start the X5, when I had the original BMW battery never had that problem, when I ship the x5 from Germany it was 3 month sitting on between the ship and peer and start it without problem, I going back to the BMW battery
:rolleyes:

Its all about what you as the consumer feel comfortable with. If. I knew I was going to park it upfor a month and a half during the mid-atlantic winter, I would have probably sought out a more robust battery. The X is my daily driver so this won't be an issue for me.

Did you register the battery to the car? This might be why the battery went out. I have used the everstart maxx batteries but had to register the new battery with the car or else it will die out

If your going to let your x sit over a month at a time I would definitely use a battery maintainer. You'll kill any battery faster by letting it sit for long periods and discharge.

Can you please clarify what this is and how to do it?

No such procedure is necessary for the E53 X5. E70's however require this.

The JOY of having older technology!

Having replaced my battery over a month ago (with no problems whatsoever I might add) I too would like clarification on this please...:confused:
