Acceptable battery drain

[RollingRocker]

I have a 2012 R3R. I installed a Bikemaster Lithium battery which has a built-in voltage meter.

I am trying to ascertain the "acceptable" amount of battery drain if the bike is sitting in my garage (undriven).

For example, with the bike completely off and kill switch "on", should the battery be draining from 13.40 to 13.38 overnight? Is this just a normal discharge rate?

Do I always have to keep the trickle charger on to avoid the battery going dead?

What is an acceptable 24 hour drain rate if the bike is off?

Thanks-

.02 volts sounds completely negligible, at that rate it would take almost 2 months to drop 1 volt

Do you R3R owners keep your bikes on a trickle charger all the time when you're not riding??

Only if it's going to be more than a few days to a week, myself

Living in SoCal I ride the bike at least one day a week and never have placed on a trickle charge

if I don't ride my motorcycle or cars in 2 weeks, it goes to the trickle charger.... but usually one good ride every 2 weeks is plenty to keep the battery running fine.
