Braille Battery - B106
$140. 6.6lbs. Fully charged, 80*F, over 500 cranking amps. CCA: 210A. Even at 210A that'd start my truck in most weather. Same cost as the color tops, AGM insides, its even recommended for large motor (V10+) daily driving. I don't see a downside other than extreme cold weather. May not have the CCA for that. Rated at 2000 10% cycles. Not sure how that'd corrolate to daily driving, but if one were to assume 1 cycle per driving experience, that's 2000 times you drive your car. Worst case, I start my car or truck 5-6 times a day. 2000/6=333 days. That's assuming I bleed the battery every time, which isn't the case. I'd expect 2-3 years for one of these at least. the Group 34 sets (what a lot of cars/trucks use) are rated at 3100 cycles. 1/3 more, so 450 days. But we know you'll get 4 years out of it if treated well. So that means for the B106 I'd expect 3 years minimum.
6.6lbs, $140, 3 years. It's my next battery when the current ones fail. but certainly can't beat $32 for 300CCA either...ahhh. choices.
Ramblings: Not a good choice for electrics, at 10A/hr it'd die pretty fast. hmm.. 10Ah/6.6lbs. compared to the B10049 at 100Ah/58lbs, not so great power density, 1.5Ah/lb vs 1.72Ah/lb. Anyone got a battery to beat that?
