Interstate has a new line of "Power Performance" batterys.
Even the in-tank Softail version will whip over a 124" @ 11.7 cr.
As far as longivity, if those are remotely close to the standard counterparts, enough said.

OE HD's bagger batterys are rated at 400 cca, as are Deka also.
Interstates Cycle-Tron are 400, Parts Unlimited are 385, and Tucker-Rocky brings up the rear at 310.
The new line of High-Perf Interstates are 500 cca, and as per the Syracuse, NY Interstate distributor, that is underated, as he said he has tested them at his facility north of 600.
Lot of phoney battery claims out there, these are not one of those.
200,000 dealers across North America can't be wrong.
