So far, Trojan T105, and Dyno (that you posted) spec about 100% more cycles from 6 Vdc batteries than 12Vdc batteries.

Rolls and US Battery, spec their 6 Vdc and 12 Vdc batteries to have about the same cycles.

East Penn does not seem to publish cycle data for FLA batteries.

My guess is that East Penn and US battery sell way more batteries in North America than Trojan and Dyno.
