The T.C.E. 15-N4820 lead-acid battery charger uses high-frequency technology and is designed for onboard charging in industrial and electric vehicles, such as forklifts. It supports WET, GEL and AGM batteries according to the programmed charging curve, while the system monitors the charging cycle. The integrated LED indicator displays the charging status: red for 0%–79%, yellow for 80%–99% and green when fully charged.

The metal housing also functions as a heat sink. The charger features IP66/IP67 protection, resistance to shocks and vibrations, protection against overheating, reverse polarity and short circuits, and automatic shutdown when charging is complete. It includes a fault diagnostic system and a soft-start function.
