What to do if the CHECK (red) light flashes on my Schumacher SSC-1500A SpeedCharge Battery Charger?
- DDiana Trevino DVMJul 26, 2025
If the CHECK (red) light on your Schumacher Battery Charger flashes before the battery is fully charged, it could be because the battery didn't reach full charge within 24 hours. This might happen with a very large battery or a bank of batteries needing more power than the charger can provide in that time. A faulty battery could also be the reason. To fix this, reset the charger by unplugging it or briefly disconnecting the negative battery clip. Then, if needed, select the desired charge rate and battery type again.
