Frequently Asked Questions
Q: Will this Makita 18V battery adapter work with all Black+Decker 20V MAX tools?
A: The MT18BPS adapter is compatible with Black+Decker 20V MAX slide-style tools (models using batteries such as LBXR20, LBX20, LB2X2020, etc.). It does not fit older Black+Decker 18V tools that predate the 20V MAX platform. Check your tool's battery model number against the compatible list before purchasing.
Q: Can I charge my Makita battery while it's attached to this adapter?
A: No. This adapter cannot be inserted into any charger while a battery is attached. To charge your Makita battery, always detach it from the adapter first and use your original Makita charger as normal.
Q: Does the adapter include a battery or any tools?
A: No — the package includes only the MT18BPS adapter. Makita batteries, cordless tools, and chargers are sold separately.
Q: Is this adapter safe to leave connected to the battery when stored?
A: For best long-term battery health, it is recommended to separate the adapter from the battery when not in use for extended periods. The built-in protection board is always active when connected, so disconnecting them during storage helps preserve battery life.
