Review on 🔋 CTEK MUS 4.3 POLAR Extreme Climate 12V Fully Automatic 8-Step Battery Charger by Sam Doucette

Charger works well. I particularly like the option to choose whether to use the "RECOND" charge program throughout the charge cycle. CTEK POLAR has worked well charging my AGM or Lead Acid batteries. However, please note that the jaws of the supplied COMFORT CONNECT clamp may not open wide enough for your application. This was when I was trying to connect to the positive terminal on my 2018 Nissan Frontier. close, but no cigar. Instead, I decided to "fix" the included COMFORT CONNECT tabs to the battery posts and that's it. This allows me to continue to use the included alligator clips on all my other batteries. All in all a solid charger with potentially limited usage for some. Rating: 4.5 stars.
