For even less you can get a similar small battery charger at Harbor Freight.

They are $10 but are often on sale with a coupon for less.

I'm almost always in favor of "for even less!". But in this case I gotta give HF's offering a double thumbs down - I threw them in the trash. Of the two examples I purchased, both appear ed to be non-temperature compensated constant voltage chargers that would not fully charge a 7 AH battery in good condition. Max float charge voltage was under 13 volts IIRC. Spend the extra and get chargers at least as good or better than "Battery Tenders".
