I thought the advantage of Makita cordeless tools was that they all

different types of Makita 18V battery fittings?
Yup
There was a time when they introduced the 4Ah and higher capacity
batteries that they made a slight change to the fittings.
IIUC the logic was that the newer batteries used of an extra pin
position to allow more communication between tools and the battery
management system in the new bats. This is not present on the old tools.
(Also the new batts can supply higher peak current, which not all the
old tools may be able to handle)
You can just remove the tab on the tool that blocks the new battery
being inserted - but you will need to take care to not discharge it too
far since the battery monitoring and low voltage cut off won't work, and
you could end up bricking a battery if you take its terminal voltage too
low for the charger to want to charge it.
So moving forward - not an issue, all LXT batts and current tools (like
DUC prefix chainsaws) should play nice together.
Hmmm
The buc122 is listed as LXT so should play with "usual" spec
Makita batteries?
All the batteries carry the LXT name, but the newer ones are marked with
a D and a star. The older LXT tools had model numbers prefixed with B,
and the newer ones D.
How new is newer? I have a mix of older 3ah & "newer" 5ah
batteries, all play interchangeably with everything I've
got...
from a new twin 18v linetrimmer, back to an old LXT flashlight.
I have yet to experience this "battery block"
I wonder if one of those lesser 1.5ah "look like LXT but actually
not" is afoot....
The smallest LXT batteries are 3Ah
Yerss. The 1.5ah *lookalikes* were sold as part of cheaper B&Q
style makita drill kits - they look like shallower LXT batts but
aren't & don't fit - G series rings a bell...

Ran into this problem with Bosch. Bought an 18v cordless strimmer on the basis that I have several 18v bosch tools and batteries but the 18v garden range uses different 18v batteries. Had to buy a battery and charger. PITA as the run time on these things is quite short so having 4 X 18v batteries would have solved that problem.
I do have a Stihl Kombi engine with its associated strimmer but thought the cordless would have been handy for the small quick jobs. Gave it to SWMBO to play with
