Automatic Battery Charger Master Watt A-10

Description automatic Battery Charger Master Watt A-10

Automatic charger Master Watt A-10 is designed for charging starter batteries with liquid electrolyte, including calcium, as well as AGM batteries. Thanks to the three-stage charging algorithm, the device provides high charging efficiency without the risk of overheating or "boiling" of the battery. The device can also be used to quickly charge a car battery as a pre-start device.

Advantages of the Master Watt A-10 charger

• Multifunctionality: Suitable for various types of batteries, including starter and AGM.
• Three-stage charging algorithm: Efficient charging without the risk of battery damage.
• Protection against overloads: The device has protection against short circuit, reverse polarity, overheating and high voltage in the network.
• Compactness: Small size and weight make it convenient for transportation and storage.
• Summer and Winter operating modes: The device adjusts to seasonal conditions for maximum efficient charging.

Operation modes

Summer mode This mode is intended for charging AGM batteries and starter batteries with liquid electrolyte at a temperature above 5°C. It consists of three stages:

1. Charge with the maximum current until the voltage reaches 14.7 V.
2. Keeping the achieved constant voltage with a gradual decrease in current.
3. Maintenance of reduced voltage to prevent self-discharge.

Winter mode Designed for charging starter batteries with liquid electrolyte at a temperature below 5°C. It is similar to the "Summer" mode, but with an increased maximum voltage to 15.4 V for efficient charging in cold conditions.
