The AEG LT20 (97025) is a high-performance, fully automatic 12V and 24V microprocessor battery charger engineered for professional workshops and comprehensive seasonal maintenance. Delivering an adaptable charge current up to 20A across an intelligent 9-stage cycle, it supports all common lead-acid battery chemistries (WET, MF, GEL, EFB, AGM). The unit features a soft-start function, a gentle 2A low-capacity mode, deep-discharge recovery from 1.5V, and a dedicated power supply mode that preserves vehicle ECU memory during battery replacement. Sensor-guided dynamic temperature compensation, a clear LED display, an integrated cable storage compartment, and multi-tier electronic protections against overheating, overcharge, and short circuits provide maximum reliability.
