The AW05-1208 automatic charger by TM "AUTO WELLE" is designed for all types of lead-acid starter batteries — WET, MF, AGM, and GEL — used in passenger cars, light commercial vehicles, motorcycles, and other types of machinery and vehicles.
A built-in microprocessor ensures a fully automatic charging process.
The charging cycle consists of 9 automatic stages.
- Battery Test. Checks the correct battery connection, its condition (functional or damaged), and voltage level before starting the charging process.
- Desulfation. If sulfation on the battery plates is detected, the device activates a pulse voltage mode. This helps remove sulfates from the lead plates, restoring battery capacity.
- Soft Start. Initial charging phase. If the battery is deeply discharged, the charger begins with a gentle charge using reduced current and voltage until a normal voltage level is reached.
- Bulk Charge. During this stage, the battery receives 75–80% of its total charge. The charger delivers maximum current.
- Absorption. Charging continues with decreasing current at a constant voltage until the battery reaches 95–100% capacity.
- Reconditioning. Prevents sulfation and electrolyte stratification in highly charged batteries and helps restore battery capacity.
- Analysis. Tests the battery’s ability to hold a charge. Batteries that cannot retain charge should be replaced.
- Full Charge. At low current, the voltage is increased to bring the battery to 100% of its capacity.
- Maintenance. Maintains the battery at 100% charge by applying periodic low voltage. This mode is time-limited to 10 days.
Packaging: cardboard box.
