My R56 is 3.5yrs old with 50K and still has the original battery. The Scangauge still holds steady at 13.8-14.0 volts, but I'm getting nervous. Is there any such thing as a "average" lifespan on the OEM battery? I can remember the days when if you got 1.5yrs on the OEM batteries you were considered very lucky! :eek6:
I'm 5 years and 60K on my battery. Tests fine. Something will give one of these days. I think 5 years on a battery is about right, but the dang battery in the explorer is 8 years old and still cranking out the amps just fine there too. I gotta think I'm on borrowed time there though.
A lot depends on where you live. Down in TX we would see 3-4 years tops since the heat really took it out of the battery.
Good grief, I'm just turning 46K at 2 1/2 years. You folks need to get off the couch and DRIVE. :lol: Jim
My first MINI didn't need a new battery until it was over 5 years old! TRUST me, you'll know when you need one.... the car had a seizure, I swear! :eek6:
What it foaming at the grill? :lol: Dwight, btw, be sure to get the heavy duty battery when you replace yours http://www.realoem.com/bmw/showparts.do?model=MF93&mospid=50964&btnr=61_2186&hg=61&fg=30 Battery, manuf.: Exide (Warranty Only) 70AH 570A 1 61217575326 $183.00 It's only $20 more than the regular one
It went into disco light show mode! Every light on the MINI started flashing! Never saw that happen before on a car with a dead battery??? ut:
I changed mine out for an Optima red top a year or so ago. I'm not a fan of cars giving me problems so it was a preemptive strike on my part.
I'm still on my original battery and it still holds a full charge. Going into it's 7th year. Once a year, I hook up my CTEK charger to desulphate and top up the charge.
On my 03, the battery went 7 years and over 100K miles. First 3 years in Manitoba, with -40F winter temps, then 4 years in St.Louis. It was still working fine, but swapped it out as a I figured one day it would just go dead on me. Mark
