I've had my Maverick for four years now, so I finally had to replace the battery I bought back in 2018. Orileys and Napa web sites want you to use a Group Size 26R, which proved sufficient for the last few years. The Group Size 35 is slightly larger, slightly more capable and fits perfectly. One could fit a larger battery still, but this is good enough.
Originally when optioned with A/C, size 24F was spec'd & 22HF without. Only four years? If I didn't get 6-7 years, I'd be pissed. There's two here from 2013, one in my Fairlane & another in my beater F-150 pickup(yeah could croak any time). One in Cobra 2017, without looking, others all 2018/19.
The 24F is still available, but the 22HF group size appears to have gone to the big battery shop in the sky. If I had a high-compression engine, a big stereo, or lived in a cold climate, the group 24F would have been a slightly larger and more capable option than the group 35. That said, the small 26R worked fine for me until it didn't.
I recently replaced my battery, late 2020, it was almost 11 years in service & still cranking strong. I've never kept a battery that long -- didn't want to push my luck any longer. I have elec. fan, ac & stero amp, can honestly say I got my monies worth. I only think it last that long cuz kept batt. maintainer over winter months. I believe it's 24F.
The Super Start Extreme Group Size 35 battery is claimed to have 640 CCA. For any given battery size, there is a range of capability. A cheaper version by the same brand has 550 CCA. I put an Size 35 Optima Red Top in my daughter's Fiat 124. That bad boy's got 720 CCA. It's great to hear about long-lived batteries. Typically I get three to five years before they start getting unreliable. Car starting battery life is reduced by extreme heat and cold, long periods of inactivity, deep discharges and predominantly short trips. With the exception of the tempature, I treated my old battery poorly. I think the takeaway is take long, frequent drives in your Maverick or Comet.
