Great value compared to OEM (which is from same supplier)

Well built and good sized form factor. Works great for my 2017 BMW M4. I like that you can unplug the connectors from the charger. If you pull the wire apart a bit (positive and negative side by side), you can connect the positive and negative terminals and close the hood if you are winter storing. I routed the cable up to the windshield and set the charger on top of a wiper.

Peace of Mind Battery Tender for storage of car with Lithium Ion Phosphate Battery

Performance car with summer-only tires sits for weeks at a time during winter months, especially if ice, snow, or prolonged freezing temperatures are forecast. Before getting the battery tender, I'd make a point to drive the car once in a while for about 30 minutes if a nice-enough day occurred. Now with the CTEK tender, I just leave it attached to the car and plug the CTEK charger into the wall, and it maintains the battery. I did attach the leads to the battery terminals - specifically to the 10mm bolts that hold each cable onto the terminal. Once that installation is complete, it is simple to plug the CTEK charger into the connector by the battery. (Note: don't attempt to install the wires to the battery posts unless you know the dangers and how to install without causing harm.) If you don't want to use the permanent connection method, the CTEK charger includes alligator clips that in most cars can be attached to the battery post connectors or to the charging ports in engine bay, depending on how your car is wired.

Great Charger and Great Company behind the product

This is my second CTEK Lithium charger. The charger does a great job and I bought a second, as I like them so much. The first one had an issue after 11 months, and Amazon would not respond for support on the 5 Year Warranty. But CTEK in the US stepped up and replaced the unit, after a quick email.... Great Charger and Great company that stands behind it.

A Bit pricey but worth it

I was originally going to purchase a $30 solution for trickle charging however, considering i have a lithium battery i didn't want to risk damaging the battery by just sitting it on a charger that would not not do anything but charge. So i read a few reviews and watched a CTEK toturial on YouTube and decided to give it a try. This Lithium CTEK (56-926) charger not only charges my battery but it regulates the charge insuch that it will charge to about 100% and cycle the battery every once in a while to keep the cells going. My Bike came with a battery tinder installed so i bought the tinder adapter for an easy plug and play setup. Overall I am really happy with the purchase as it was worth the extra for a better charging solution.

THANK YOU CTEK, BEST OF THE BEST

So far I'm very happy with this...

This is my first lithium charger and I'm still on the fence. So far, this product is working well. The light indicator is easy to read to determine where in the charging process it is in. It's small and compact and easily fits in the bag that this comes with. It does take a bit longer to charge my 100Ah 12v lithium batteries, but I would suspect this is the case at the amps it delivers. That being said, for what it's used for (end of trip top offs) it works well. I can't honestly provide a recommend yet, but I'm pretty happy so far.

Great charger for F80 M3

Works really well on the F80 M3 (and M4 should be no different). Compared to their chargers for traditional batteries, this is even simpler to operate. The only negative I can say is for this price it would be nicer if they provided better quality alligator clips, but if they do break they are replaceable without buying a new unit.

Excellent professional grade Lithium charger.

When you are tired of the value tenders from the big box stores, this is your upgrade. The build quality and functionality of this charger is second to none. This is a must have for a Lithium battery. I burned through too many batteries that were insufficiently or incorrectly charged. I wished I had found this earlier. If you care about what this is hooked up to, this is the one. Love how it tells you the progress of the charge. Highly recommended.

Best for the lithium battery

I had Shorai Lithium eXtreme battery that was sitting in the bike flat for more then 6 months Triad charging it w my old charger and couldn’t “lift it off the ground” Considering prices of lithium battery, I looked into chargers that could recover completely drained unit and came across this awesome product. It took only couple of hours and my battery was in the green zone. Super happy with the performance and I hope it lasts!

Charges perfectly

Works exactly as advertised. Charged and maintained my 2016 BMW M4's battery perfectly. I believe BMW brand names this charger and charges significantly more. I had multiple issues with the NOCO charger on this same vehicle, setting off alarms on my car and getting so hot you could not touch it. Don't take a chance by saving a couple of dollars, these Lithium Ion batteries are very expensive.
