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: Works well. - 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.

### ⭐⭐⭐⭐⭐ Works great and saves my battery
*by R***E on December 30, 2025*

Been using this in my 2021 BMW 228 while it is stored for winter. It is user friendly and easy to use. I can unhook it and start up no problem and it is maintaining the battery well. No complaints and much more affordable than the BMW branded battery packs which I hear are made by the same company
