It is compatible with most Makita 18V BL-series battery packs. Please verify your specific battery model's slot type before purchasing.</p> <h4>Q: Does using two batteries at once damage the batteries or the tool?</h4> <p>A: No. The parallel connection keeps voltage the same at 18V while combining the capacity of both batteries. This is safe for compatible cordless tools and batteries, and the flame-retardant ABS housing with internal ribs helps manage heat during extended use.</p> <h4>Q: How quickly can I attach or detach the adapter?</h4> <p>A: The plug-and-play design with precision metal contacts allows you to slide the adapter onto the battery slot in under three seconds — no tools, wiring, or modifications needed for quick setup and removal.</p> <!-- production-packaging-notice --> <h3>Production &amp; Packaging Notice</h3> <p>To maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
