Very Reliable

I use these AXTRA smart battery maintainer to keep my batteries charged.I live in a very cold climate and keep my vehicles in a unheated garage all winter. I have four AXTRA smart chargers that keep my two four wheels a tractor and my battery for my zero turn mower charged up and ready to go.I've been using them for about six years and never had any problems with them they just work very reliable !

Fully automatic car battery charger maintainer.

AXTRA smart battery charger maintainer is designed for both 6-volt and 12-volt batteries, this is a fully automatic 8-stage charging system. This battery charger for climates where the weather continually impacts battery performance, this charger can be used as a trickle charger, desulfator, and battery maintainer. This is when it will start monitoring the battery's voltage and maintain the battery with a float charging current. Compatible with 12-volt lead batteries, AGM, and gel cell batteries, this charger is safe to use in just about any situation. I have a Lexus is350 that's driven infrequently. On several occasions when I went to use it, the battery was weak and I was just able to start car. So I bought the AXTRA battery charger, which is a perfect match for the cars battery type and capacity characteristics. The battery charger restored the car battery to full charge, and is now operating in maintenance mode. With the AXTRA car charger, now when I need the car, its ready to go. Keeping your car battery working shouldn't drain your bank account. That's what makes the 12-volt battery charger and maintainer such a popular option. It includes lengthy cable; you can connect it from just about anywhere. Simply connect it to your vehicle using the included battery clips or O-ring terminals and let it do its job. This car battery maintainer can be used an automatic trickle charger and after it's done monitoring the whole charging progress, it will automatically switch to float mode.

Smart battery charger for car, SUV, trucks, ATV.

I've recharged the batteries in all my vehicles, Lexus GX 460, Honda Accord, Toyota Camry and Jeep Grand Cherokee. Two of batteries are approaching 3 years old. All batteries now start my vehicles as if they are brand NEW. It's very nice to use a battery charger, battery maintainer and trickle charger on our weekend car because it takes up very little space. I'm very happy with this battery charger. Amazingly the battery charger has been working fine since day one. Now it is plugged in to the battery all days and weeks. This battery charger has good features to keep battery in maintenance and charged.
