Hi , Just looking at your discussion about the impact drivers and noticed that you said the 1.5 ah Makita battery would'nt fit on any Makita tool unless its white? are you sure I think that all Makita slide Lithium fit all lithium tools as long as it's the same platform i.e 18v
Here's a quote from Velosapien,
The compact 1.5 ah batteries will NOT fit on the blue tools. There is a small notch on the tool preventing them from sliding in. That can easily be cut off and they should work but I'm not willing to try on my new tools. I'm not sure why Makita wouldn't want you to use the compact batteries on the blue tools. The only drawback should be shorter run time but they can come in handy for some very tight spots or in an emergency if you find yourself with no charged 3.0 ah batteries. I would love to use these batteries on the impact driver to make it even smaller. Besides, they charge in under 15 minutes with the new rapid charger so its not bad.
