2 CTEK Multi US 3300 Battery Charger
The Multi US 3300 is a more compact and streamlined version of the charger above. You might be surprised how much power you can get from a charger that’ll fit in your palm. It’s the ideal charger for use with household vehicles, equally easy to use in your garage or on the road.
We love that the Multi US 3300 is a truly all-purpose charger. It’s all-weather, first of all, and functions well in a range of temperatures and climate conditions. You can even permanently attach it to a problematic battery for continuous maintenance.
There’s one downside to its small size: the cables are equally compact. It’s a stretch connecting them on even a standard car battery. Aside from that, the design is user-friendly. The use of icons with LED light indicators makes it easy to interpret for a layman.
Even though it’s small, this charger has about the same charging time as the model above. It will also test and desulphated your battery, handy extra features you might not expect in a unit this small. That combination of convenience and functionality earns its place on this list.
- Cold mode for use in extreme winter conditions
- Tests and improves battery condition while it charges
- Lightweight and portable
- Can stay connected even while the battery is running
- Safeguards against sparking and short circuits
- Included cables are a bit short
- Won’t save settings between uses
Who’s it for?
Smaller vehicles and engines.
3 CTEK 40-206 MXS 5.0 Battery Charger
If speed is what you’re after, you probably want to check out the CTEK MXS 5.0. It’s the fastest charger in the CTEK arsenal. Anyone charging larger or more demanding batteries will find this one right up their alley, as well.
A combination of higher power output and advanced temperature compensation provides the improved performance of the MXS 5.0. A lot of chargers run extremely hot, but not this model. It’s more efficient, and that translates to a faster charge.
Now when we say faster, keep in mind this is still a trickle charger. You’ll need a few hours to get a car battery from empty to full. Where you’ll most notice the speed increase is when you’re topping off a battery, which it does in a blink.
The status indicators on this model aren’t quite as easy to interpret as the others above. The flip side of this is it gives you more information, like whether your battery is sulfated. Changing programs and modes are simple, too.
The MXS 5.0 is a must-have if you have a larger battery. It’s versatile, too, and any car owner can benefit from the powerful and intelligent design.
- Fastest CTEK charger
- Powerful charge great for larger batteries
- Temperature sensors prevent overheating
- Works well on both standard and dry cell batteries
- Multiple programs adjust charge to size of battery
- Remembers program settings between uses
- Controls and indicators a bit harder to interpret
- Won’t work with the CTEK cigarette lighter adapter
Who’s it for?
SUVs, trucks, and other larger vehicles
Why Buy CTEK Battery Charger?
As mentioned in the introduction that CTEK is consistently on the cutting edge. That’s not the only thing that draws people to these chargers, though. Here are some of our favorite features, which you’ll find on all the chargers reviewed above.
Recondition and Desulphation Modes
Most CTEK chargers will both desulphate and recondition your battery. The recondition function can restore even badly discharged batteries back to their full capacity. By continuously charging it, the battery maintains maximum capacity – a great thing for its long-term help.
Desulphation is a term you might not be familiar with. It’s basically equivalent to cleaning out your battery. Lead sulfate crystals are left behind during a battery’s charge cycle. Over time, these can build up and lower the battery’s capacity. CTEK chargers remove these crystals, improving performance.
Advanced Safety Features
Most battery chargers have a polarity protection feature which will prevent use if the clamps and poles aren’t connected right. CTEK chargers also have spark protection. If the clamps are accidentally touched together, the charger will shut down automatically, keeping you safe.
Smart sensors and charging
All CTEK chargers will automatically choose the right charging mode, proceeding through the charging steps without any user input. Many will also let you know valuable information about your battery, with indicators telling you the sulphation level and overall battery status.
Many charger brands claim to offer smart sensors. Those in CTEK chargers truly follow through, taking accurate readings and making the right decisions to operate at maximum efficiency.
Our Verdict: The Best CTEK Battery Charger
These are all great products, but if pressed we’d have to say the CTEK 40-206 MXS 5.0 is the best overall. It has everything you’ll find on the others but adds power and some handy features.
