Two words for when my battery goes...........LITHIUM ION!

Small, light, no explosive gas venting. Can drain/recharge with 100% life. MB has started using L-ion and others are following their lead.

Arent lithiums horrible in excess heat and cold? Correct me if im wrong - or maybe car tech ones have something special to overcome that...

I picked up a new Bosch battery a couple months ago. Group 43. Group 45. Whatever it takes.

$110 at pepboys.

Denis, you had to start another battery thread!!!!

lol

from what I had read over the years, the original battery supplied with the car can last about 4-10 years (very wide spread!!). the OE battery installed from a US dealer are NOT the same as the OE batteries installed at the factory - don't ask me why, probably has to do something with the logistics (i can understand it for non-US made cars, but the X and the Z??)

I would suggest going for the right size, maximum available crank-amps and the AGM - supposedly the AGM technology in acid batteries is the new sh!t!!!

I paid for mine (was it H8?) about $150 from Advanced Auto Parts - you go online, find the battery at your local store, pay for it there using their 20% coupon, and then come to the store and collect your battery... on top of that you get a $25 coupon for $50 purchase, so once you have a coupon, go online and order a set of 8 NGK plugs for $60-$25=$35

Voila!!!

:iagree:

yeap... just what he said!!!!

And we post the same time too, Term. Great minds think alike :D :beerchug:

Use TRT30 for 30% off at this time.

Many years ago, I went into Pepboys and looked at their booklet showing which batteries they had fit the X5. I then looked at their shelf and saw the correct Bosch battery, produced within the last 6 months, sitting there. I paid for it and walked out.

It wasn't any fancy AGM battery. It was just a stock replacement SLA battery. It was also made for the V8 X5's, but it was cheaper than the not available 3.0i 5 battery. Buying a battery isn't rocket science, especially if the X5 is a DD and it gets used often.
