CTEK MXT4 Eight Stage 24V Battery Charger Maintenance Rugged IP65 For Caravans Boats

The CTEK MXT4 is a rugged, eight-stage battery charger built for 24V systems—perfect for caravans, boats, or heavy-duty industrial applications. With IP65 protection and a compact design, this maintenance charger stays connected for months and keeps your batteries in peak condition, ready when you are.

Eight-stage, fully automatic charging for 24V lead-acid batteries

Experience a comprehensive charging cycle that does more than just top up power. The MXT4 guides every battery through eight automatic steps, combining precision electronics with CTEK’s proven charging philosophy. Desulphation pulses gently break down sulfation, soft start protects severely discharged cells, and a controlled reconditioning phase helps recover capacity that’s been lost to deep discharge. A dedicated maintenance pulse keeps the battery healthy over the long haul, so your 24V system remains dependable year after year.

• Desulphation mode with pulses renews sulfated cells, restoring performance in many aging batteries.
• Soft start for deeply discharged batteries protects from shock and extends battery life.
• Recondition mode provides controlled top charging to recover capacity in severely discharged cells.
• Maintenance pulse charging prolongs battery life and maintains peak performance during long-term storage.
• Charging even drained batteries to bring them back from the brink and into a healthy charge.

Broad compatibility and practical capacity

• Supports virtually all 24V lead-acid batteries: Wet, MF, GEL, and AGM.
• Charge range: 8Ah to 100Ah batteries, with maintenance up to 250Ah.
• Output: 24V at 4A, delivering precise charge without overloading delicate cells.
• Temperature-compensated charging ensures optimal voltage across temperature variations for consistent results.

Smart, efficient, and safe for year-round use

• Input range 170–260V with low ripple and low back-current drain for reliable operation anywhere you park.
• High efficiency at 85%, so less energy is wasted as heat and more goes into your battery.
• IP65-rated enclosure protects against dust and water intrusion—ideal for boats, caravans, and industrial environments.
• Compact design with mounting holes for permanent installation anywhere you need reliable protection and maintenance.
• 5-year warranty provides long-term confidence in challenging environments.

Why this makes a difference for your 24V systems

Whether you’re storing a caravan for the off-season, keeping a boat battery topped up during frequent use, or maintaining industrial 24V packs, the MXT4 does the heavy lifting. It not only charges but also analyzes battery health, identifies faults, and proceeds with a cycle that optimizes longevity and reliability. By delivering precise, temperature-compensated charging and reducing the risk of sulfation and stratification, this charger helps you avoid abrupt failures and unexpected downtime.

Ideal use cases

• Seasonal vehicles: leave the MXT4 connected to your caravan or boat battery to keep it healthy between trips.
• Industrial 24V systems: maintain essential batteries in forklifts, fleet equipment, or remote installations.
• Long-term storage: the maintenance mode supports prolonged connection without compromising safety or battery life.

With the CTEK MXT4, you gain a reliable 24V maintenance charger that combines intelligent eight-stage charging, versatile battery compatibility, and durable construction. It’s the smart choice to revive, charge, check, and sustain your 24V batteries—so you’re never left stranded when you need power most.
