    Hi did anyone solve this problem? I replaced L6599AD IC and MIP2M2 IC but same. Relay, triac, MOSFETs, all zener diodes good. Battery is good. Anyone can help me?

    >>21904430 When this problem occurs, the culprit is the microprocessor, which cannot be replaced because it must be programmed with the official firmware, which is not available online.

Topic summary

LABEL_AI_GENERATED
The Hilti C 4/36-350 charger stops charging about 10 seconds after a battery is inserted. The battery was confirmed to be good by testing it on another charger. Later replies suggest troubleshooting the charger’s power/control section, including replacement checks of the L6599AD and MIP2M2 ICs, relay, triac, MOSFETs, and zener diodes, but the fault remained unresolved. The final diagnosis states that the likely cause is a defective microprocessor, which cannot be easily replaced because it requires official firmware that is not available online.
