    My 12volt converter went out on my RV, so instead of spending 500 to have it replaced, I installed this on the battery. Since the RV is at a permanent lake site with electric, this does the job.

    Nice black ,resilient case won't crack or break, good small size 6X2 5/8x3 3/8 inches deep, with nice bright front LED indicators that show if it is charging yellow ,trickle Green , or misconnected Red. I hung it from ceiling- with a stiff wire, using velcro cable ties to dress leads, plugs in near garage opener so I do not need a table or floor space, near L.H. door and wired the 4runner so that it can be connected without opening the hood. Unit comes with big battery alligator clamps, terminal lugs and a cigarette lighter adapter so that you can connect in various ways. The connectors are bullet, push friction connectors and I applied petroleum jelly so rubber will pull apart and disconnect- if pulled on. Put some paper signs to warn- Disconnect Charger, so I don't drive off with wires connected. Monitored the voltages and it charges to 14.30 volts ( Yellow LED-Charge Mode- 43 watts line power- 2.33 amps charge current through Tenma 72-7745 meter and then switches to Green LED-Trickle mode 0 watts {killawatt meter} 63 ma trickle current . As the battery terminal voltage falls from the computer and other loads the voltage declines to 13.18 volts and the cycle begins again as the unit automatically ladles energy to keep the battery at peak condition- but below the gassing voltage ( assume 14.50 VDC?). This is on a standard antimony battery, toyota 4 Runner 2004 SUV summer California 75 degrees morning line voltage 119.9VAC driven ~ 5 miles every 15 days. Previously smaller, wall-wart style that went for a year or so before failure. Opened it up and blown capacitor aluminum electrolytic 16 V and hazardous design with 120 VAC terminal against a component. So after I fired the B. Butler, tried this Schumacher Speed Charge SC-300A .Great Walmart price $24 and Your mileage may vary!

    This is a great maintainer for batteries that are in storage. I use it on my mower during the winter months to keep it fully charged. I like the fact that it is fully automatic so you don't need to set a timer and monitor it. Also it is a 3 amp -- most others are 2 amp. You will be happy with this maintainer.
