What to do if Black & Decker 25Amp says check battery connections?
- AAnne Garcia DVMJul 27, 2025
If the Black & Decker Battery Charger displays 'CHECK BATTERY CONNECTIONS', it typically indicates a poor connection to the battery. To resolve this, observing the “Important Safety Instructions” at the front of this manual, disconnect the AC cord and clamps, clean the battery terminals, and then reconnect them. If the issue continues, consider having your battery evaluated at a certified automotive service center.
