The Best

by - verified purchaser
The Battery Tender Jr. for your bike is the best. I only ride my bike about once month during Winter and the battery tender keeps my battery going for it rest time. Also you can't beat the price that Jafrum has for this item.

A Must Have!

by - verified purchaser
I ordered 3 of these, 2 for me and 1 as a gift. I have done a lot of research on this product and you can't find anything better for your bike. I don't think you will ever find a better price either. Both of my bikes are plugged in and I know my batteries will stay in good shape for years. I highly recommend it.

Extends battery Life!!

by - verified purchaser
This is my sixth Battery Tender Jr. I use them on all of my summer toys when stored for the winter and winter toys stored during the summer. I used one on my Boat battery since it was new in 1998. I finally had to replace the boat battery in 2012!! Prior to battery tender, the battery would fail after a few years (likely due to freezing). I highly recommend Battery Tender.

Perfect & Simple product

This is my second one. Need two now, got a lawn tractor. It does exactly what it is supposed to do. The indicator light lets you know how charged your battery is, for the most part. I love it. Great price and service from Jafrum, as always.

A must have for any bike!

by - verified purchaser
I got this to keep my battery charged when not riding my bike, I haven't used it much since I've been riding a lot lately, however install was a matter of minutes, love the SAE cable attachment that you can install and leave, easily tucks away out of the way, I also purchased the USB charger that attaches to the same cable. Like the title says, everyone should have one to keep you battery alive and a great way to connect more gadgets to charge your phone, gps, music etc...

Battery tender junior review

by - verified purchaser
Having ridden into February in 2013, I didn't believe in winter battery failure. But, in 2014, when I couldn't ride at all and learned new phrases like "polar vortex," I became a believer, although maybe too late. So, I bought the battery tender from Jafrum, hooked it up, and it seems to have saved my battery. I won't know until it's cold again. But it did revive it from the dead. Very reasonably priced, by the way. At my local Yamaha dealer, this battery tender is almost twice as expensive. Great investment to save money!
