CTEK's newest 4.3 amp charger adds a true lithium mode to everything the MXS 5.0 does. If there is a LiFePO4 battery in your car now, or might be later, start here.

Lithium batteries save real weight, which is why they show up in so many track and drag cars, but they need their own charge profile. The NXT 5 has it, along with normal and AGM programs, so one charger covers every battery you own.
CTEK lists the NXT 5 as the replacement for the Lithium US and the Multi US 4.3 Test and Charge. It charges in stages, checks the battery and maintains it for as long as it stays connected.
Frequently asked questions
Do my old CTEK accessories fit?
Yes. The NXT 5 uses the Comfort Connect plug, so eyelets, extensions and indicator panels all work.
Fitment: All 12V vehicles with lead-acid, AGM or LiFePO4 lithium batteries
