If only! It’s all about the £££ though sadly
You think they could get together & standardise batteries for portable tools. One of the advantages of a competitive market, every manufacturer tries to get an edge on all the others & customers can distinguish good from bad batteries can't they? I don't think so. Just another area where customers loose out.
No they tend to not make batteries compatible with other makes of tools. Sorry
Will this fit a Makita radio?
