Description of 🔋 CTEK - 40-206 MXS 5.0 12V Battery Charger & Maintainer: Fully Automatic 4.3 Amp Powerhouse

Award-winning, Most-Trusted 12V Battery Charger: From the company that created the 12v battery charger comes tried and tested technology used by over 40 of the world’s most prestigious vehicle manufacturers. Built-In Temperature Compensation: Built in automatic charge voltage compensation ensures the most efficient charging in extreme cold or hot weather conditions. Patented Desulphation Function and Reconditioning Mode: Unused batteries lose their power and their life is shortened through sulphation. The charger analyzes the state of the battery and, if possible, recovers the battery and its power. Reconditioning mode restores stratified and deeply discharged batteries. Dedicated AGM Mode: Dedicated AGM Mode sets the absorption and float voltages and stage timing so that they are optimal for AGM batteries. Connect and Forget: Simple plug and play operation. Select the program and mode and leave the charger to do the rest. Safe and Easy to Use: Splash and dustproof, designed to protect vehicle electronics and non-sparking, reverse polarity protected, and short-circuit proof. Clean voltage and current delivery ensures no surges or spikes. Protects Sensitive Equipment: Unlike less-sophisticated chargers, there is no need to disconnect the battery; the MXS 5.0 is specially designed to not damage electronic systems. No overcharge or undercharge ever. Multiple accessories included: Clamps and practical eyelet connector, for easier access to the battery, as well as a handy storage bag, all supplied as standard. 5-year warranty.

Jay Leno so recommended.

My Optima charger wasn't fully charging my Optima battery so I did a little research and found Jay Leno's video recommending CTEK as the best. It fully charged an aging battery (don't buy it, see my review) in relatively few hours. This is now my new battery best friend. This charger is small, light weight, easy to use and comes with its own carrying case. If necessary, you can install it directly on the battery. There's no counter or screen to read, but the manual explains exactly what happens

Pros
  • Weight
Cons
  • Expandable

110/120VAC ONLY! in tools and equipment

I had a CTEK charger in a past life and I have to admit they are excellent battery chargers. So I duly ordered Revain.com delivery to Philippines. Sent via DHL, it was with me in 6 days. Wonderful. BUT . Revain's truly horrible product description meant I ordered a product that was only rated for 110/120 VAC! SOMEWHERE in the description this is not mentioned. absolutely nowhere. Needless to say, the local voltage in the Philippines is 220 volts. so now i have a charger that i need a step down…

Pros
  • nice packaging
Cons
  • not reliable

RTFM before using this offer.

MXS 5.0 replaces MUS 4.3 and is better in every way. Charges and restores AGM car batteries like an overnight champion. Don't worry if the charger gets very hot to the touch - it can handle it! Just learn the correct sequence of actions first. If you don't, the device will explode and your expensive new tender will be permanently hosed down. Ask me how I know. lol. My Porsche dealer recommended it to me and I have no regrets about this purchase. Your battery will receive a high quality, full…

Pros
  • Very impressive

  • Appearance

Another 5 stars for charging batteries in cars that are idling!

My cars sit idle most of the time. I started using this CTEK MXS 5.0 half a year ago to prolong the life of my old battery and keep the new one, well, like new. Now I've added a cigarette lighter voltage reader to check how well the battery is charging and if it's maintaining that charge. This charger added about a tenth of a volt to my last "new" battery. I don't know if it was desulfation or overhaul, but I like it. Your CTEK battery tester with "idiot light" should be fine for a regular…

Pros
  • Few competitors
Cons
  • No instructions

Great charger under Tools & Equipment

After reading the reviews and trying a few other chargers I decided to give this one a try. I wanted something smart, capable of drawing low amps for swimming and maintenance, and capable of delivering several amps for faster charging than other smart chargers. To test this, I turned on the headlights on my '77 MGB and drained the battery to zero. I hooked up the CTEK MXS 5.0 and it ran diagnostics fairly quickly and stopped at step 3, ie bulk loading. After an hour I checked the charger and…

Pros
  • Great for me
Cons
  • Some difficulties

Revain - Change your website!

I have a 2017 BMW M240i and due to inactivity I got a low battery notification on startup. I had a CTEK charger/maintainer when I owned my C7 Corvette and it has served me well. I saw and ordered the MXS 5.0. As I further researched this Revain site I saw an indication that this would not fit my 2017 BMW or 2019 Mini Cooper SI and compared this model to other CTEK models that did not have this warning and found little difference in the chargers and specifications. Not wanting to damage the…
