Eyes on the battery-purchase ;-)

All cordless tools with an asterisk (Makita-Star Technology) in addition to the battery contacts, this means the loss of critical surveillance. The current Makita battery BL1830, BL1840 and BL1815N (N! 1.5Ah) have a built-in logic that allows an extension of the service life and higher power demands.

I have bought in the past few months many Makita cordless tools. From various sources (Amazon, retailers and eBay). For all tools with 18V batteries work instead of the intended BL1830 also much lighter BL1815N. Only in 36V adapter (2x18V BL1830 series) for chainsaw BUC250 and hedge trimmer of BL1815N does not according to the catalog. In practice, however wonderful and the relatively large device makes super-easy.

I use practically all devices every now and then the light BL1815N. Especially if I want to have the lightest possible tool. This is such. As the hammer drill as wood chisels, the impact wrench in an unfavorable position or the Circular Saw with very fine and precise cuts.

Of the BL1830 is available here at Amazon two variants. An older and a newer lt. Amazon info text. I ordered the newer version and get a BL1830 with Makita-Star. The older BL1815 (1.3Ah) fit mechanically into the machine, the newer BL1815N Makita-Star machines, however, can in all (? With me already) be used.
