The three-stage charger Suoer MA-1220AS is designed for efficient and safe charging of all types of oil-filled batteries, including AGM, GEL, starter, as well as lithium-iron-phosphate (LiFePO4). This is a reliable solution for home, service and professional use.
🔋 Operating principle and features
The charger operates according to a three-stage algorithm, which provides an optimal charging mode without harming the battery:
- ⚡ Initial charge — supplying the main current until the rated voltage is reached
- 🔋 Saturation — current reduction at stable voltage
- Support — bringing the battery to 100% capacity with a small current
The charging voltage is 14.4 V for gel batteries and 14.6 V — for other types, including LiFePO4.
The maximum charging current is 20 A. It is determined automatically, but manual adjustment is also available using the battery capacity switch:
- 🔧 60 A·h — up to 6 A
- 🔧 120–160 A·h — up to 12-16 A
- 🔧 200 A·h — up to 20 A
Important: after the green indicator lights up when charging a LiFePO4 battery, it is recommended to leave the battery connected for another 30-40 minutes — during this time, saturation with a small current occurs. Without this, the battery may be undercharged by 5-10%.
🛠 Design and convenience
