⚡ At a Glance
- • Charging Performance: 5A output for 6V and 12V batteries with Force Mode and precision pulse charging
- • Best for: Owners of cars, motorbikes, caravans, boats and garden machinery needing reliable maintenance and recovery
- • Not ideal for: Large commercial batteries that require charging currents well above 5A
Compact 5A smart charger for 6V and 12V lead-acid and LiFePO4 batteries with automatic maintenance and desulphation. Integrated thermal sensing adjusts charging to ambient temperature and built-in protections prevent overcharging.
Recovering deeply discharged batteries – with Force Mode and pulse desulphation
Force Mode permits manual charging down to zero volts while precision pulse charging detects and reverses battery sulphation and acid stratification. Charge is accepted from as low as 1 volt for hard-to-recover units.
Revives neglected or flat batteries that many basic chargers cannot, reducing unnecessary replacements and extending usable battery life.
All-in-one maintenance for multiple chemistries – with automatic multi-chemistry support
Automatic charging modes cover 6V and 12V lead-acid types including AGM, EFB, Gel, SLA, VRLA and Start-Stop, plus lithium-ion LiFePO4 batteries. Continuous monitoring adjusts charge cycles to match battery condition.
Suitable for a wide range of vehicles and leisure kit, allowing safe long-term connection for seasonal storage and routine upkeep.
Safer charging in variable conditions – thanks to thermal compensation and overcharge protection
An integrated thermal sensor dynamically adjusts charging parameters according to ambient temperature, while overcharge protection prevents excessive voltage during maintenance. Multiple safety checks monitor for faults and abnormal conditions.
Reduced risk of undercharging in cold weather or overcharging in heat, making year-round battery care low-maintenance and dependable.
