\"It Just Works\"
January 28, 2012
Using this to keep a 20 Ah gelcel battery charged that runs a 12Vdc pump that pressurizes our water supply. Unlike many \"smart\" chargers, this one isn\'t \"so smart that it doesn\'t work at all\".

Instead it gracefully accepts the occasional 10A draw from the battery, and then happily tops it up -- no errors, no mysterious shutdowns. Thus it \"Just Works\".

I am buying another one to add battery backup to another pump.

My only wish is that the cooling fan would shut off instead of running continuously, and that BatteryJunction would get this product on Amazon.com with Amazon fulfillment. Nothing wrong with Battery Junction, but they would sell a lot more via Amazon, and then I could count on the product persisting in the marketplace (and perhaps being upgraded with a thermostatically controlled fan).
