CTEK – 40-206 MXS 5.0 Fully Automatic 4.3 amp Battery Charger and Maintainer 12V

Great maintenance charger for Sprinter van
Prime Day sale made the value exceptional. Charger is excellent quality, decent instructions, works perfectly. I was previously charging Sprinter van battery with my motorcycle trickle charger, which was okay, but not ideal. This charger made a big difference in charging time and end result was a higher final voltage. Can plug in and forget as it works great as a maintenance charger. I had to add-on the silicon bumper/protector and extension cable for the battery clips – so final cost is higher if you need those options. Only complaint is proprietary plugs which means I can’t use the cables from my existing charger. CTek makes a charger with Mercedes-Benz branding – this is the same charger but without the lithium battery capability and M-B branding, so almost half the price (on sale). Highly recommended.

Works really well, but long time for cycles
Read the manual, it is very helpful. This unit has multiple cycles, or modes. To restore or charge a battery. Once the type of battery is selected, AEG or regular, then it goes through various cycles of sensing, charging, restoring/reconditioning and then maintaining charge long term for a car battery. There are cable attachment choices, clamps or rings to attach with bolts. Takes many hours but does it’s work effectively. Manual gives the time duration of various stages. Charged a battery fully, that was getting an error on our black & decker charger (F02 internal short or something).Size is very compact and a pouch case is included.

Best Trickle Charger for a C6 Corvette
This is a fantastic battery charger that has worked perfectly for me and my C6 Corvette for the past 6 months. In particular, for any Corvette owners reading this, like me, you are concerned about your ride’s battery draining. That pesky parasitic drain is something we just have to deal with on these cars, and this charger takes care of that and more! Not only does it maintain your battery’s charge and prevent the drain, but it also optimizes the battery and reconditions it, helping to improve lifespan and performance. This CTEK model in particular is pretty much the exact one used by Chevy as the OEM Corvette battery charger (just branded as Corvette and costs almost double). Overall it is very easy to use & easy to read and know where it’s at in the charging process with corresponding lights. There’s a section in the included user manual which tells you what is occurring at each step in the process.My only slightly negative observation is a very slight “buzzing” noise coming from the charger when plugged in, but otherwise, it has worked flawlessly for me and has helped keep my battery charged up and ready for action!

Perfect for gentle charging and battery maintenance for vehicles in extended storage. Smart charging with multiple stages and supports AGM batteries (commonly found on German cars, where the battery is in the trunk). Once charging is complete, it keeps a steady eye on when a top-up is required, as vehicle electronics continue to slow draw while in storage. In watch mode (most of the time), it only consumers 0.8 to 1.8 watts. Its truly a set and forget charger. Even after a power outage, it remembers its settings and continues to monitor the battery and only charge when necessary. The BMW OEM version is the exact same as this CTEK model. The extra money for this charger is well worth it to not overcharge your battery.
