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.

I had 2 red top Optimas in a 4 year period, I will never purchase another one.
I bought an Odyssey battery and it is great. They are a little pricey and are heavy but it has never failed on me like the Optimas did. The Sears Platinum is the same battery I found out after the fact for less money. Good luck

Thanks Kevin. I'll keep that in mind should the Ctek unit not revive the Optima

Hey Jody, On the Optimas that you saved, how long did that take? Are we talking a few hours or a day or more? The Ctek unit arrived yesterday so I had it plugged in over night. It quickly went to the third light, absorption, and stayed there over night so about 16 hours. I figured it wouldn't take that long to either go into recondition mode or throw an error saying the battery was bad but, I'm not sure either.

Thanks

Mine didn't take that long.

Well, crap. Ok, I'll be patient and see what happens. Thanks, Jody.

Did you pick the recond mode?

I only use C-Tek chargers... they're fantastic little chargers.

Yep, and I let it sit over night again without it going past absorption. Got fed up and just bought another one today since it basically was holding me up from any other work I wanted to do. This is Optima's last chance. I'll leave it on the C-tek unit for the most part and see what happens. Admittedly, I expect a lot for my $200. If I don't get it, I won't buy them again.
