Makita 18V LXT questions
Why do some batteries say 18V and others 20V?
They are the same class of battery, measured at two different moments. Five lithium cells in series read about 20V fresh off the charger with nothing drawing from them, and settle to about 18V once a tool is running. A brand that prints 20V is quoting the first figure and one that prints 18V is quoting the second. That is why an adapter between an "18V" platform and a "20V" platform works: there is no conversion to do.
Will this fit my other Makita batteries?
Only Makita 18V LXT batteries. Makita also sells Makita 18V Ni-Cd/Ni-MH, Makita 36V, Makita 10.8V CXT, and those use a different socket — same brand, different rail and terminals, so they need their own adapter. Compare the sliding rail on your battery against the photos before ordering.
How do I find the right adapter on this page?
Use the selector at the top: pick the platform on the other side of the pair and it takes you straight to the one adapter that joins them. Every combination in that list is one we actually make, so if it is there, it exists.
Can I go the other way round — run Makita 18V LXT tools from another brand’s battery?
Yes. Use the swap button next to the selector above and the page turns the search around, from Makita 18V LXT tools back to the batteries that can run them.
Can I charge a Makita 18V LXT battery through the adapter?
No. The adapter carries current from the battery to the tool and does nothing else — there is no charging circuit inside it. Keep charging Makita 18V LXT batteries on their usual Makita charger.
Will an adapter damage my Makita 18V LXT battery or my tool?
Used with undamaged, compatible equipment it is not expected to. Makita 18V LXT batteries are lithium-ion with their own protection circuit built into the battery, and it keeps doing its job through the adapter. Stop when the tool noticeably slows rather than running the battery flat, and stop using the adapter if it becomes unusually hot or the contacts look damaged.
Does it work with third-party Makita batteries?
Usually. What matters is the socket, not the badge: if the battery slides onto a Makita 18V LXT tool and locks the way an original does, the adapter will take it. Aftermarket batteries do vary in moulding, so if yours looks unusual send us a photo and we will check before you order.
