    • excellent
Simple, out of the way, and does an excellent job. I take lead-acid batteries seriously, and charging them can be dangerous for various reasons... the gases emitted, the danger of explosion, etc. So I was a little reluctant to buy this to keep my riding mower battery charged when not in use. But it revived an old battery and seems to be perfect for maintaining that charge if you keep it attached. Small, simple, single-purpose and not too fancy – that is exactly what I like, in my whiskey, my women, my tools and my battery chargers. ... show more

    • Easy to use, and works great!
Got for my 2015 FZ-07. Super simple instructions, and works great. I like the lighting that tells you charging states as well as if the battery is bad. Very durable design. And the power output calls for a speedy charge, also love that you can keep it plugged in indefinitely while not in use.

    • It works as it should.
As stated by another purchaser: I bought a BT Junior to keep my Honda generator ready to go and it’s working perfectly. Small, simple, and safe [and the terminal on the included SAE cord are perfectly compatible with the screws on the Honda battery terminals]. I like that it’s specifically safe for long-term storage, and it’s keeping my battery topped up and ready at all times. It’s solid and compact, and I’d definitely recommend. ... show more

    • Battery Charger
The battery charger/maintainer work great I have several cars and every few weeks I was taking the big charger out and charging up each vehicle. I purchased several of this charger and now I don't worry about it. Just unhook them and go. Best purchase I could have made.

Simple to use and works very well as a "trickle charger" for my generator. Good price. Highly recommend.
