Designed to handle the entire 12V and 20V MAX Li-Ion battery family, this charger powers up a depleted pack in an hour or less, so downtime stays short. If you own more than one DEWALT tool, the DCB101 is the practical buy that covers every pack you already have.
Which DEWALT batteries does the DCB101 charge?
It charges all DEWALT 12V and 20V MAX Li-Ion batteries, including compact packs (DCB201, DCB203) and XR packs (DCB230, DCB240, DCB606). No matter which 20V MAX tool you reach for, the charger is ready.
LED diagnostics: what the lights mean
The DCB101’s LED indicator gives you real-time feedback. If you see a flashing red light, it usually means the battery temperature is outside the safe charging range — the battery is too hot or too cold. Move it to a room-temperature spot and try again. A steady red light may indicate a power line problem or a pack that needs replacement. Understanding these DCB101 charger error codes saves you from unnecessary replacements and keeps your work on schedule.
