CTEK MXS 10 Universal Battery Charger 12V 10A for Car Caravan Boat with Eight Step Smart Charging

Meet the CTEK MXS 10, a versatile 12V battery charger built for caravans, cars and boats. With intelligent control, durable construction and purpose‑built features, it keeps your battery ready when you need it most—and it can even power your devices when the battery is out of the circuit.

Smart charging that protects and revives your battery

The MXS 10 uses an eight‑step, fully automatic switch‑mode charging process to deliver precise power where your battery needs it. It starts with a gentle desulfation cycle to break up lead sulfate crystals, then progresses through bulk and absorption stages to refill capacity quickly, before finishing with a pulse maintenance phase that keeps the charge stable during long periods of non‑use. This intelligent sequence not only charges faster but also helps extend battery life by reducing wear from repeated deep discharges.

Universal compatibility, practical performance

• Supports lead‑acid batteries in multiple chemistries—Wet, MF, GEL and AGM—from 20Ah up to 200Ah, with maintenance charging up to 300Ah. It’s ideal for seasonal vehicles that sit for long periods and need reliable revival when you return.
• Desulfation (RECOND) to recover deeply discharged cells and restore performance, helping older batteries regain usable capacity.
• Maintenance pulse charging keeps the battery at 95–100% state of charge, ready for your next trip without overcharging.
• Low back current drain and low ripple help minimize energy loss and electrical noise in your vehicle’s systems.

Four versatile settings for real-world needs

• 14.4V and 14.7V modes for standard charging profiles that suit most lead‑acid batteries and OEM recommendations.
• 13.6V/Supply mode provides a stable float voltage—great for maintaining a full charge without overcharging, and serves as a power supply for devices when the battery is disconnected.
• Boost mode at 15.8V for up to 4 hours delivers a surge of current to recover sluggish batteries more quickly when you’re in a hurry.

Supply mode: power without the battery

In Supply mode, the MXS 10 provides a constant voltage of 13.6V with up to 7A of current. This makes it possible to run 13.6V‑rated equipment or keep electronics powered while the battery is being serviced. Note that the spark‑free protection features are not active in this setting, so use with appropriate care. This mode is especially valuable for seasonal setups where your caravan or boat needs power even when the battery isn’t connected.

Powerful, efficient, built to last

• High efficiency at around 85%, reducing energy waste during charging.
• Input range of 170–260V, so it’s reliable across different mains supplies and regions.
• Compact design with mounting holes for secure, permanent installation in your vehicle or storage space.
• Includes a connection lead with clamps for quick, straightforward setup.
• 2‑year warranty for peace of mind and long‑term reliability.

Who benefits from the MXS 10

Ideal for caravan owners who store their vehicle for extended periods, boat owners who need dependable battery health on seasonal voyages, and car owners who want a robust, flexible charger that can handle a range of lead‑acid batteries. If you’re replacing an aging battery, preparing for winter storage, or simply keeping multiple batteries in peak condition, the MXS 10 offers a practical, capable solution.

Practical tips to get the most from your MXS 10

• Connect the charger to a battery that’s not connected to high‑draw gear to avoid voltage spikes during start‑up. Use the appropriate mode for the battery type and capacity.
• For seasonal Use: leave the charger connected in Supply or Maintenance mode to keep your battery at a healthy full charge without manual intervention.
• Utilize the RECOND/desulfation cycle if you notice sluggish charging or poor performance on older batteries.
• When using Boost mode, monitor the battery and remove the load if the voltage climbs unexpectedly to protect both the battery and electrical system.

With the CTEK MXS 10, you’re choosing a charger that does more than top up a battery. It actively protects, revives and maintains your power systems across caravans, cars and boats, ensuring you’re ready to go whenever the road, water or ferry schedule allows.
