That's what I have been accustomed to the last 5 years with my Bandit, take the battery out before the freezing temperatures, trickle charge with a Canadian tire bought battery charger, and when the warm temperatures come, put in the battery, push the start button, and voila!
(I do go through a putting back into service maintenance routine, but not before enjoying a quick first ride.)
Last night it was sunny and +10 after supper. I grabbed the battery and installed it. It seemed too large for the battery tray. Not a good omen.
Tapped it down with the palm of my hand, put the key in the ignition and turned it. Wouldn't even illuminate the dash lights. Battery charger showed full charge.
Grabbed my multimeter; 2 volts.
Time for a new battery.
Ordered one this morning; but couldn't pick it up before the shop closed. Damn; it's going to be sunny and +11 tomorrow.
Well; a couple of more days and I should be back in the saddle again.
