CTEK Battery Chargers and Maintainers

A battery that sits is a battery that dies. Cars stored for the winter, weekend toys and anything with a modern alarm or infotainment system pull a small current all the time, and a few weeks of that is enough for a no-start and a sulfated battery. CTEK chargers fix that. Clip one on, plug it in, and it charges, tests and then holds the battery at full for as long as the car sits.

This is the full CTEK line we carry. The MXS 5.0 is the go-to maintainer for most cars and light trucks at 12V and 4.3 amps. The NXT 5 does the same job and adds lithium battery support. The MXS 7.0 and NXT 15 put out more current for trucks, big batteries and deeply drained ones. The CT5 Powersport is sized for motorcycles, ATVs and UTVs. The CS ONE is the app-connected model, the PRO25S is a shop charger and power supply, and the D250SE handles dual battery and solar setups on overland rigs and campers.

Need to start something right now? The RB 3000 and RB 4000 jump starters get a dead car going without a second vehicle.

The kits pair a charger with the accessories most people end up buying anyway: a comfort indicator eyelet so you can see charge status at a glance, an extension cable, a wall bumper or a 12V socket plug. We also have vehicle-specific kits for the Corvette, Mustang, Camaro and Bronco. Every CTEK charger ships free.
