Yuasa Charger

This is inexpensive and nice to have. Connect it to the battery when the F6B is not being used.
I know of GoldWing Owners that have been able to obtain 6-10 years of life from the Batteries because they had been on a trickle charger when not riding.

$30 is a lot less than $100 for a battery every 2-3 years
