I agree with Paperkrain. Additionally, I have had my '05 Venox for almost three years and i've put two new batteries in it. The guy that I bought it from said he put a new battery in it the year before I bought it. I replace the stator (or generator), that didn't fix my problem, then I replaced the voltage regulator and that WAS the problem. I bought a battery charger at walmart to charge the battery, but it still dies if it sits over winter. I took it to a bike shop and they said my charger won't even touch the battery, so they charged it for me and I haven't had any battery issues this summer and I ride about 250 miles per week.
