Hi people - my old t3 has an Odyssey PC680 battery in it. Was there when I bought the bike. A bout three and a half years ago. The recommended one is a PC925, but I`m not sure it would actually fit - their website says it is 7 inches wide. What do you think? One other thing - I ride my bike in town with the lights on mostly. Seems to drain battery. With a multimeter across the battery, the old girl needs some revs to get up to 14 volts. This normal? Cheers.
