Battery Tender Jr works very well
Pros: I am using the charger for 6v batteries for a toy tractor. It works very well, and clearly indicates when batteries are fully charged.
Cons: None

Battery Tender Jr. 6v Smart Charger BTjr6v021-0127
Pros: I needed a charger for a child's ride on car. The charger was not the usual charger, but after a bit of time and energy I found what I needed. Customer service was very knowledgeable and was able to fill my order and ship almost immediately.
Cons: None - product has performed as expected.
Other Thoughts: Very happy with purchase, I know long after my grandchild has outgrown the car, the charger will still be useful.

Battery Tender Jr 6v
Pros: It was easy to hook up and seems to be working well. I have it hooked to my Model A Ford as a trickle charger.
Cons: The only fault I found was in the directions for hooking it up to the battery. It my case the positive lead for the ground was to be hooked up to the frame. I saw no reason why it could not be hooked up to the positive post of the battery which I did because it made life a lot easier.
