CTEK 56-926 Lithium US | Fully Automatic Lithium Ion Phosphate LiFePO4 Battery Charger | 5.0Ah - 60Ah | Maintenance Charging up to 120Ah

CTEK works perfectly on my Lithium battery. If you think its expensive, check the price of the Lithium battery for your car. As all CTEK products, this one is solid.

The new Range Rover with the BMW Twin-Turbo V8 is one fantastic SUV with new battery technology and a lot of electronics and other systems demanding a healthy dose of voltage and amperage. Even though this high-tech SUV has very smart battery monitoring systems, having it connected to this CTEK every night is just peace of mind. One small inconvenience is you won't be able to lock the vehicle when the engine hood is open - for some reason they programmed the alarm system this way - but I ended up finding a way to safely route the wire when the hood is closed down so no issues. If the Range Rover isn't driven in 4 days, it automatically enters in sleep mode but the CTEK will take a few more days to enter into the last stage (last LED lit) of just varying inputs and testing. A must have battery charger/maintainer for any modern vehicles.

Excellent quality, easy to use, functional this is the best brand tender that I have used.

Lithium batteries can lose their charge over time when parked for extended periods, particularly when its cold. Modern cars never sleep, there's always a small current drawn. The CTEK keeps the battery charged and its connector can be configured to allow access without unlocking the car or opening the trunk/hood; many cars require elaborate procedures to unlock the car and access the electrical system to resurrect the vehicle.

Fast Delivery, thanks

This is what you need to keep your Li battery in good shape year around.

I bought this for my BMW F-90 M5 . It worked as advertised, I left on for >24 hrs. When I first looked all lights were illuminated. And ma battery was reading 13.88 VDC.

I purchased this charger 5 days ago to recharge my new Lithium Antigravity AT12BS RE-START Battery installed in my chopper and it works beautifully. The CTEK Brand is recommended for the RE-START BATTERIES because of the Battery Management System (BMS) built into the battery, providing Over-Discharge Protection. This CTEK (56-926) LITHIUM US 12 Volt was the actual model recommended by the manufacturer.

I bought this trickle charger for my new bmw m4 for when I’m away on holidays as the replacement battery is 2800$ plus tax, thought I’m deffinetly gonna take care of it, so I’ve had it on the charger for last 2 weeks and it appears to be doing what’s it’s supposed to. Great price considering BMW will try sell you the exact same one just with their logo on it for 300$, literally double the price. I didn’t have to select any modes or anything, just hooked it up, plugged it in, and it went right to work.

This Tech product meets the new requirements for my 2024 mild hybrid vehicle, maintaining the battery during seasonal storage and reduced use.
