40A 12V Intelligent Multi-Stage Mains Battery Charger

This 40A 12V automatic multi-stage mains battery charger is designed for safe and efficient unattended charging of a 12V battery or battery bank from a mains power source (220-240V AC). The charger features an advanced 7-stage charging process that delivers faster and more efficient charging while eliminating the risk of voltage fluctuations. It can charge a single 12V battery or several 12V batteries connected in parallel, provided that the batteries are of the same type, capacity, and age. This mains battery charger is compatible with Lead Acid batteries, including AGM, Gel, and Wet cell batteries.

Key features:

- Safe unattended charging: The unit features inbuilt safety functions (protection against DC short circuit, overheating, overcharging, and reverse polarity of the battery), allowing the charger to be left permanently connected to the battery for unattended automatic charging. The charging voltage is free from peaks, offering smooth uninterrupted charging.

- Continued charging during battery use: The charger will continue to operate while energy is drawn from the battery during use and will maintain the charge if the battery is already at full capacity.

- Boost-charging feature: This preliminary charging stage can improve battery condition and recover lost capacity from older batteries, thereby increasing battery life and preventing premature battery failure.

- Dead battery recovery: The desulphation stage can break down sulphation that occurs in batteries left flat for extended periods of time, returning them to a full charge.

- Automatic temperature control: The inbuilt fan is automatically enabled when a high temperature or charging current is detected to maintain an optimal internal temperature.

- LCD Display: Shows vital information regarding the charging process (charging voltage / charging current / different charging stages). LED lights also indicate the battery type.

- Power pack function: Provides a direct supply of power to a 12V load (e.g., 12V fridge) with no battery connected (e.g., during battery replacement).
