Got a new Yuasa for mine as it came from Demark with a Lithium Bomb fitted - after a couple of runs at the end of the year after the hell of the DVLA registering it, stood for 4 weeks and the Lithium battery was totally dead too! And nothing on mine to drain it as it's in race trim. Battery was new when I purchased the bike
I have 2 Ctek lithium chargers for the batteries on the Pani R & 1098R. They both spin over like a washing machine on a spin cycle.
Think i may do likewise for next year Stu and get myself a Yuasa too... it was kind of a blessing as work had decided to put about 50 tonnes of salt all over the campus as it was a little bit nippy first thing...
You guys do know that cold lithium batteries like to be warmed up by switching the lights on or similar??
