This did not work. Tried everything here and have the same issue. 2019 Sondors Smart Step. Battery indicator on LCD says 3 bars. Plug into charger and charger light stays green, battery does not seem to charge as after 6 hours charger light still green, and battery indicator is at 3 bars. Reset to default several times, still not fixed. Removed battery. Plugged into charger and pushed red power button--3 green lights lit up. Also, tried another charger with same symptoms--green light stayed on like battery isn't taking a charge.
