  1. 01

    Verify Your Makita Battery Model

    Check the label on your Makita battery to confirm it is an 18V LXT lithium-ion slide battery. Compatible models include the BL1860B, BL1860, BL1850B, BL1850, BL1840, BL1840B, BL1830B, BL1830, BL1820, BL1820B, and BL1815. NiCD, NiMH, and older V18 batteries are not compatible with this adapter.

  2. 02

    Confirm Your Milwaukee Tool is M18 Compatible

    Locate the battery slot on your Milwaukee cordless tool and confirm it accepts M18 18V lithium-ion battery packs. The adapter’s top connector replaces Milwaukee battery models such as 48-11-1860, 48-11-1850, 48-11-1840, 48-11-1828, 48-11-1820, 48-11-1815, and related variants. Old V18 tools are excluded.

  3. 03

    Insert the Makita Battery into the Adapter’s Bottom Slot

    Slide your compatible Makita 18V LXT battery into the bottom slot of the XFYBZN adapter the same way you would insert it into a Makita tool. You will feel the locking mechanism engage when it is seated correctly. Never force the battery — proper alignment ensures safe electrical contact.

  4. 04

    Attach the Loaded Adapter to Your Milwaukee Tool

    With the Makita battery secured in the adapter, slide the adapter’s top connector into the Milwaukee M18 tool battery slot. The adapter’s compact profile (4.32 × 3.0 × 3.69 in) keeps the overall assembly manageable. Once locked, the tool is ready for normal use at 18V lithium-ion performance levels.

  5. 05

    Remove the Adapter Before Charging and When Storing

    This is a passive adapter — it cannot charge the battery and will not fit into any Makita or Milwaukee charger. Always detach the adapter from the Makita battery before charging, and store them separately. Remove the adapter from the battery when it is not in use to protect the contacts and extend the life of both components.

Makita to Milwaukee Battery Adapter — Customer Reviews

Product quality

Solid Fit, Works as Described

The adapter snapped onto my Makita BL1860 battery without any issues and slid right into my Milwaukee M18 drill. The locking mechanism felt firm and I had zero play during use. A genuinely useful tool for anyone running both platforms on site.

Ease of use

Saved Me From Buying More Batteries

I already had four Makita LXT batteries fully charged and picked up a Milwaukee circular saw. This adapter meant I didn’t need to buy M18 packs on day one. The ABS housing feels solid and the compact size keeps the tool well-balanced in hand.

Overall experience

Clear Instructions, Simple Setup

The warning label on the unit is clear — do not charge with this adapter attached. Once I understood that it’s a passive converter and not a smart battery, the whole process made sense. Easy installation, reliable connection, and it handles my Milwaukee reciprocating saw without any drop in performance.
