Last spring I installed a Shorai battery in my bike. The bike has sat since mid November without being connected to a charger, today the weather was 17?C when we got home so I checked the tire pressure and the temptation to start the bike over came me and I was surprised that the battery started the bike instantly. So almost for months without use and it had enough charge to start the bike. Maybe Friday afternoon I will go for a short ride, hoping for a bit of rain between now and Friday.
