Battery Chargers

[piaabro210]

Sorry I meant to post my previous message under the E70 forum:

First of all I want to thank X5 Meister and Penguin for their very informative battery posts! Based on their writes up I went ahead and purchased the CTEK 3300 from Amazon.com $54.99 plus Free S/H.

Ever since my last years debacle with the X5 battery crapping out on me, I've had the ever concern on looking at getting a battery tender. The dealer ended up changing out the old battery under warratanty but told us the reason it died was because of the "Frequent Short Trips" error message.

Here's the kicker! I just got the CTEK 3300 2 days ago, I went out today to give it a whirl. So I go to move the X5 closer to an electrical outlet in the garage. AND THERE FOR THE VERY FIRST TIME WITH THE NEW BATTERY, I GET THE DREADED ERROR MESSAGE "HIGH BATTERY DRAIN." How crazy is that!!

One question for you guys that own a CTEK 3300...For my 08 X5 should I be using the car function or snow flake/AGM function? I appreciate the help!
