Replacement Battery PCB for Selected Makita 18V Packs

Choose a replacement circuit-board component for a professionally assessed compatible tool-battery assembly. The MT18PCBA listing is for the board, not a complete charged battery.

• ✅ Replace the board as a component - retain only other parts proven suitable by the repair assessment.
• ✅ Compare the pack layout - connector and indicator positions can be checked against the original.
• ✅ Keep the package scope clear - no cells or complete battery are supplied.

Exact Pack Revision and Electrical Compatibility Matter

The title names selected Makita 18 V BL1830/BL1815-style applications. Confirm the exact board, pack housing, cell arrangement, sensing and charger requirements rather than relying only on the battery-platform name.

Battery assembly requires suitable expertise, testing and protection. No manufacturer-original identity, verified current rating or restored pack safety is promised. Do not use the board to bypass protections or retain damaged or unsuitable cells.
