OP here: FWIW Just completed a charging test on my new Li and previous AGM battery. Li full charge was 100% from factory (indicator on top of battery) out of the box installed in my R18. No battery charger used and motorcycle put in storage after two weeks 99%, after 4 weeks, 96%, after 9 weeks 94%. Did a full charge with my NOCO charger set on Li...it took <30 minutes to 100% charge. Now R18 is out of storage. The previous factory AGM in storage last year with no trickle charger; after 2 weeks storage 78%, after 4 weeks 62%...then put on charger, 12 hours to 100% charge (note this was the factory 2 year old AGM). Just an interesting observation and I assume the batteries were drained from R18 factory installed equipment.
