Review: Works great, came highly recommended by 'car guys', highly recommend! - Jay Leno talked about this unit on his show and praised it highly, he's a real car guy plus I highly doubt Jay's endorsement could be bought. I plugged mine onto what had been a healthy 12V car battery that tested at only 11.6 volts when resting. Overnight, the charger went through all 8 steps of charge/test and had a green light. Now the battery tests at 12.6v Maybe any other charger would have restored it that well but this thing puts the battery through a lot of steps to improve and insure it's 'health'. Highly recommend. High quality, fast charge, great power, easy to attach, LONG cord, easy to use basically plug'n'play. The instruction manual however, not so great. I viewed some youtubes to make sure I understood the various functions, there are plenty of them, turns out this is a very popular charger for real car guys.
Review: 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.

*by R***R on December 28, 2025*

Love the CTEK chargers and have not had one problem with them or any car they have been on. Will charge any battery has a low rate of charge so will not damage electronics in cars and a fraction of cost of OEM chargers. Weight is irrelevant but it comes with a carry bag.
