Awesome charger
Bought 2 of these a couple months ago. Using them for my cbr 1000rr and my John Deere lawn tractor. They are great. Hook them up and leave them. No worries about no starting in the spring. Highly recommended.

Great little charger!
I found Canada's Motorcycle to be an excellent choice for online purchasing. The product arrived exactly when it was supposed to and was exactly as pictured. The pricing was reasonable in comparison, and the Battery Tender Jr. works like a charm. I'm very pleased with the overall shopping experience and will definitely be ordering from Canada's Motorcycle .ca again.

Works well
I have it plugged in right now, it keeps my 3 batteries charged. The quick disconnect allows me to switch it to another battery quickly. The light that changes colour from red to green makes it very easy to assess the current state of the battery.

Does the job,
I've had this charger for a year or more now, and completely happy with it. Just plugged it in and left it,the battery is still as strong as the day I bought it. Very good product and fair price. Cheers.

Great value, works well thus far
I've owned it from December to February (so a little premature to write a review), so far, it seems to be doing its job as intended.
I'll check back in next season to see how well it's doing, but I'm guessing it's well worth the money.

Does the job
If it doesn't break too quickly, then it's a good buy; so far so good (after just a month though).

Can an extension cord be used or does it need to plug directly into an outlet
Battery tender would recommend using their own extension cables with this item. You can find them here:

Can I charge two batteries using one battery tender which is shown in this page?
What's shown is you have two ways to connect to a battery, crocodile clips or pigtail, whichever more convenient to you. This tender does not provide a way to connect to two batteries at the same time.

I have an ultimate plug attached to by battery. Can I just plug it in, or do I have to change the plug attached to the battery?
This needs to be plugged either with the crocodile clamps or the quick attach harness.

Hello, Can this product be used with a lithium ion battery? Thanks for any information!
Looking at buying a 1.5 amp charger when the car gets put away for the winter. As I'm renting a space the owner is not really happy about plugging one in for the winter. I know there are a lot of variables, we're in Southern Ontario. What would you say is a fair price to pay him? December to end of April. Thanks for any help, I know they burn next to nothing, but I have to keep the person happy.

Is the quick connect cable universal i.e. can the quick connect cable be used with every trickle charger on the market or is the quick connect specific to the charger?
The quick-connect cable comes with a standard SAE plug that can be used with most trickle chargers that use the same type of plug. It is however not recommended to use with other brands as it would void the warranty on any of the other chargers it is used on.

Yes, the included wall plug-in is 110V.
