Why is the “BATTERY IN ERROR” LED on my Max 1500 PRO on?
- AAnna PowersAug 16, 2025
The “BATTERY IN ERROR” LED might be on for several reasons. First, ensure the “BATTERY Plug” is properly inserted into the “BATTERY IN” port. If AC power is lost, the operator switches to battery backup mode; check if the Toroid box AC POWER ON/OFF SWITCH is ON. If the battery is very low, check if the AC power ON/OFF switch is ON and verify AC power. If the BATTERY TEST fails and the “REPLACE BATTERY” LED is ON, the battery needs replacement. Also, ensure the battery is plugged into the BATTERY INPUT port.
