Alternative to Optima

[WSSix]

I have two tenders. One was on the Ninja that I sold recently and the other stays plugged into the Duc, and, you're correct, they do need it. I've got the ring terminals connected to the battery and the pigtail tucked away on the frame. I just pull it out and plug it in when I park the bike. I'll do the same thing with the Ctek unit and the TA. I'll just leave it in the trunk and keep it plugged in.

Thanks everyone.
