About Battery Sustainer Plus 12V 2-10A Battery Maintainer

Works with almost all vehicle batteries: regular lead acid, AGM and gel cell in cars, trucks, lawn and power sports equipment. Just connect the alligator clips or hard-wire the ring-terminal connectors to your battery terminals, plug it into a wall outlet, and it will maintain a constant 100% charge. Microprocessor-controlled technology cuts-off when the battery is fully charged, to prevent damage from overcharging. Spark-free and temperature-compensated, with short-circuit and reverse-polarity protection. Lead length from the Battery Sustainer Plus to clamps is 72". Output is 2-10 amps. 5-year limited warranty.

I use one of these to maintain the two AGM batteries on my diesel truck that I don't drive often. The only complaint that I have is that the AC cord really needs to be longer, but my application is probably a little unusual.

Matches the 2 top name brands on the market. Great Item! (Posted on 2/4/13) Review by Joe

I have looked at battery maintainers for a long time to see what the best ones are. So I finally bought 2 Battery Minders and 2 Battery Tenders. These are suppose to be the 2 top rated brands on the market. The battery minder gives the extra benefit to desulfate a battery. Then I saw this at Eastwood, It has all of the features of the 2 top brands with an extra feature of 10 Amp Charging and Desulfating. So I hooked it up and measured the voltage during the different stages of charging. It cycles through the stages at the exact same voltages as the 2 other brands I own. The other 2 are not really for large automotive batteries because of the low amperage of .75 amps and 1.25 amps. The battery Sustainer has has 2 AMPS and 10 AMPS, plus a cigarette lighter adapter. I have used on 3 different batteries and it works EXACTLY like the 2 top brands, But much faster with the 10 amp charge. It is now my Favorite. I will buy another one. The L.E.D. readout gives much more detail than the others. I bought others, before these but most of the others charge at too high of a voltage, and worked very slowly. Trickle chargers are a thing of the past, in time they will ruin a battery. You need the Float charge feature of the Sustainer to be able to leave it on for long periods of time. This is the best deal on the market with the quality of the top name brands.

The 12V 2-10A battery maintainer has everything over the flaot chargers on the market, it keeps your battery charged and well maintained, not like the others on the market that over charge or don't keep your battery maintained properly. When you want to take your classic car for a ride on a sunny day you just put that key in start it up and Cruise.
