    7.5 Amp fused Battery Charging Harness with ring terminals and 7.5 Amp fused alligator clip charging harness
1.25 Amp Weather-Resistant Battery Charger is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from If you don't, you'll regret it sooner or later. I've had my 2012 Trike for almost a year now. I'm what's known as 'casual' rider. I ride maybe four times a week; short hops and longer rides. I rode to my dealership to get the bike serviced and the battery went toes up at the dealership. It was an expensive lesson for me. If you're like me and not someone who's not turning heads at the stop light every day, GET A BATTERY TENDER! Thank goodness my battery died at the dealership instead of somewhere out in the "lonesome country"! I've only had it three weeks but it has served me well. From the minute I plugged it in it started charging immediately. Now I have just one less thing to worry about. I don't recommend that casual riders like me buy this product...I DEMAND IT! Buy one now!

Rated 5 out of 5 by from Excellent Tender! This is an excellent tender sold by HD. It is fully weather resistant and fully charges the battery in the advertised time of 4-8 hours. I have left mine running as it sits inside of it shell with no issues what-so-ever. If you are in the market I would most definitely give this a try!

Is it working for input 240V?

I bought this one from San Jose - US dealer with the part number is 66000033. It shows this tender is universal fit, and the package also mentions that it is can use 100 - 240V. However, the label stick in the tender mentions "Part No. 022-0185-HD-WH Input: 120V ~0.35A 50/60Hz Output: 12V..., 1.25A" as the picture attached. The serial of the tender is (S/N): 2815-100602C I am not sure if this is wrong sticker or my misunderstanding. Please let me know if I can use 220V for this tender? Thank you.

Independent charging?

Can this item be charged in the home and independently be used to jump start my 2013 Harley Road Glide Custom away from a power source?
Asked by: terryrushing902
Hello Terryrushing902, This is a battery tender and not a jumper pack. It only charges the battery while plugged in and not a remote power source. Thank You!
