My battery on my 916 seems to be getting tired, its seems to have lost some energy and is not taking a full charge when out on a run and is charging on the optimate when I return from a run for over 2 hours! I have had the old girl 4 years now and never touched the battery and had a new rectifier / regulator fitted less than 1000 miles back
Can anyone tell me the best / cheapest online battery supplier that there is?
