The original battery on my 1999 ML430 finally gave up ghost. I am trying to find an aftermarket battery here in Manitoba, Canada. The MB dealer here wants $267 for an OEM battery. My CAA membership's battery service normally will supply and install a battery on site but unfortunately they do not have a battery size for the ML. Does anyone have any experience with Magnacharge batteries? (I believe they are made by Trojan) They have one sized for the ML but is rated at 820 CCA listed for $169.99. It comes with a 60 month prorated warranty and 2 yr free replacement. The other one I can find is from NAPA, their Legand rated at 875 CCA and listed for $213.89 with a prorated 72 month warranty and 2 yr free replacement. Incidentally, the MB OEM battery only come with a 2 yr free replacement and 3 yr prorated. So it seems I am paying a lot for not any more protection. I like to know if anyone have any experience with both the Torjan and NAPA. Thanks.
