I just now jumped into the battery operated outdoor power equipment.
The final straw that pushed the decision forward was the realization (stumbled upon during research) that 15 different states in the USA now have laws against gas powered blowers. These laws run the gamut from simply restricting days, times, and duration of usage, to an all out ban altogether, depending on the local municipality of jurisdiction. California has over a dozen cities that I am aware of that restrict the use of 2 stroke gas/oil powered OPE.
As 1 Lucky Texan above said... these types of bans would not have been possible without the existence of quieter, less locally polluting alternatives, that with the advent of lithium ion battery technology, have become more viable and safer for the application (no accidental cord cutting when wielding a hedge trimmer) in the cordless battery format, vs corded.
I went with Makita, because Makita had more variety of tools in the OPE sector alone, than any other battery operated garden tool company I reviewed... nevermind Makita's 200 other construction tools that use the same 18V LXT battery format in 18V and 36V arrangements.
When other OPE battery company's advertise 40v, they are likely doing the same thing as DeWalt... citing the superfluous surface charge that can be measured on a battery immediately after being freshly charged on a charger... rather than the nominal "running" voltage the battery maintains in actual use, which is what Makita cites.
My new battery operated OPE is in the mail as I type... a string trimmer, a hedge trimmer, and a small chain saw. I look forward to being freed from pulling cords of any type, whether starter cords or power cords. I look forward to being free from figuring out how to dispose of bad gas, and wondering if I mixed the gas 40:1 or 50:1, or if I mixed the gas twice by accident. I look forward to being free from the smells and the noise of 2 strokes. I look forward to no longer worrying about near misses with extension cords. I look forward to simply being free.
But one thing the battery operated tools won't set me free from... the actual doing of the work. Ugh. Maybe it's ok that the shipment is delayed.
