Automatic Battery Charger Master Watt A-25

Description automatic Battery Charger Master Watt A-25

Automatic charger Master Watt A-25 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 be used as a pre-starter to quickly charge the battery on board the car. Compact size and light weight make it convenient to use.

Advantages of the Master Watt A-25 charger

• Versatility: Suitable for a variety of battery types, including AGM and liquid electrolyte starters.
• Three-stage charging algorithm: Efficient charging without the risk of battery damage.
• Overload protection: Protection against short circuit, wrong polarity connection, overheating and high mains voltage.
• Compactness: Light and compact solution for charging batteries with a capacity of up to 25 A.
• Summer and Winter operating modes: Optimized charging modes for different operating conditions.

Operation modes

Summer mode Designed for charging AGM/GEL batteries and starter batteries with liquid electrolyte at a temperature above 5°C. The mode includes:

1. Charge with the maximum current until the voltage reaches 14.7 V.
2. Maintenance of voltage with a gradual decrease in current.
3. Maintaining the battery at a low voltage level to prevent self-discharge.

Winter mode Mode for charging starter batteries with liquid electrolyte at temperatures below 5°C. The algorithm is similar to the "Summer" mode, but with an increased voltage to 15.4 V for effective charging in cold conditions.
