My 2007 Z4MC is still going strong on the original OE battery. I hook up the Battery Tender if it's parked in my garage for more than a couple of days.

I chickened out and replaced my battery at year 8. I Tender"ize" my MC the same way you do. Hope things are well, BTW... our paths haven't crossed in a long time. |

Yes. Ive got both the M Roady and the CLS63 on the Battery Tender Plus. Rarely get to drive them bc time
Quick Note- if you use leads (if they come with your battery tender(not the alligator clips)), you can stick them in between the terminals and just have it permanently there instead of having to take off the alligator clips every time you go out to drive. Mine came with a nice quick disconnect cable as well and it has a cover for it too! Overall, its a good ~$45 investment to keep the battery going strong. My original battery died so I had to change that.

You guys can't use the CTEK recondition cycle on the AGM battery in the e9x M3. Z4M and e46 standard battery was FLA, but can be upgraded to AGM at Autozone for example, which I did before I sold mine.
Beware. Over-voltage (above 14.8v) will cause the pressure release valve to blow inside the AGM and ruin the Hydrogen recycling and balance of the electrolyte inherent in the AGM design. The recondition mode takes voltage up to 15+ volts and is for flooded LA batteries that are sulfated.

Anything over 2 weeks of sitting and I usually throw a battery maintainer on it.
(5) cars, (1) tractor, (2) trolling motor batteries, (2) chargers/Desulfators/maintainers, (1) Desulfator/maintainer. I use BatteryMINDer brand. I can attest that these maintainers dramatically increase the life of my batteries. All vehicles have hard wired plugs so no clips required. 90 Corrado 18 yr old red top AGM 07 Z4MC 5 yr old FLA 01 525i 9 yr old FLA 97 S10 ZR2 8 yr old FLA 96 4runner 11 yr old FLA 01 John Deere 10 yr old FLA 2x 35 AH AGM for kayak 4 yr old |

Seattle! Very tempting! Especially with the inevitable summer heat that is coming. (Hard to believe given the past winter....) If we do plan on getting to the PNW I'll let you know well ahead of time. |
