Highly, Highly Recommended

We all use many tools and utilities and appliances and devices in our everyday lives. Many of these things work well, and some frustrate the heck out of us. This little device is a true gem. In my book, it ranks among the absolute best devices in terms of its usefulness and utility and also its quality of construction. It is easy to operate, and the instructions manual is well-organized and very clear.I have used it to recondition (not just charge, but recondition) my various car batteries many, many times. The reconditioning feature really and truly works. It brings batteries back from the dead and makes them work like brand new batteries. It has paid for itself fifty times over for me. I highly, highly recommend it.

Excellent battery upkeep for cold weather lesser driven vehicles.

This battery charger/maintainer works excellently with almost no effort to recharge a weak battery or maintain a battery in cars that aren't driven regularly. This is especially important in colder weather as the charge can drop enough to be unable to start the vehicle. This almost happened to my 2011 BMW 535i Xdrive 95Ah battery after not moving it for 2 weeks mid winter. I got several low charge warnings but thought they would go away once I drove a bit, but trips were far and few between.The charger power cord is hard wired, and the output leads have a fast clip connector at the far end to plug in either the alligator clip ends or 1/4" eyelets for a more permanent connection to make frequent charging easier.Both the power cord and the output leads are 6' long for a total of 12' plus another 18 inches for either the alligator clip or eyelet connectors, so there's plenty of length to position the charger where you want. The clips are spark free and have polarity protection so you don't have to worry about those when making your connection.Plugging the device in starts it in standard vehicle battery mode. Other modes include motorcycle for smaller vehicles, AGM for those batteries, and a reconditioning mode to restore full capacity to batteries that have lost some charge capability.From almost dead, it took about 28 hours to go through all 7 phases of charge. Patience is the way to go here, don't check often, especially if you have to open a door or hood to do so.I found it best to leave it under the hood with it slightly ajar and check every 4 hours or so. Resist the urge to unplug it because you think it's not progressing. It is. Even in cold weather it will get your battery back in great condition with little more than the press of one button. Highly recommended.

Great for maintenance of your car battery

Works great at charging the battery up without over charging due to it's graduated charging cycle. Then it goes into watch and maintain mode. It comes with a permanent pigtail to instal for ease of connecting to your car. It also has alligator clamps for use on other cars.

Great Charger, Recommended by Many Car Makers

Great battery charger and conditioner. Works great with my BMW, as it’s actually a twin to the official BMW charger, made by the same company. Other High-end European cars use the same unit, too.It also has other settings, like motorcycle battery. and I use it over the winter to keep my garden tractor battery in good shape.I feel safe leaving it connected for days or weeks, if necessary. It can’t over-charge with its programmable settings. If you’re not paying attention, it will even tell you it’s not hooked up properly, and won’t start charging. Great device.

Seem to work well.

The item is and seems to work as described. Only recently received and started using the item so can't comment too much in detail about how well it works. While the instructions for set up and use are relatively simple and easy to understand, perhaps there could be more information about how the unit worlks.For example, what will happen when the battery is fully charged. It seems the charging lights will remain on, but the unit will not continue charging the battery and will resume charging only if the battery starts losing its charge.Maybe the unit could have a light or indicator when it is in the maintenance mode.
