Re: 08 r6 charging issue.
Remove any modifications, such as lights, quick shifters, etcetera.
Voltage drop test your various connections; including grounds. Voltage drop tests are best performed when said wires are at their maximum potential loads.
Batteries that are deeply discharged, often face a shortened lifespan, and may even require immediate replacement if left that way for long periods.
