My bike is out in the cold - no garage for me. I try to plug the battery tender every other day for maybe an hour or so after it turns solid green. Did so on Sunday and will do again tomorrow. Hopefully the single digit cold has not gotten to the battery yet.
In the teens here. Rode to work it was 25 expect it to be 15 tomorrow morning . Plugged in the battery to the charger during the day. Brought the charger to work in case it happens again in the a.m. bought a newbbattery need to charge it up before I install it.
