“My weed eater, leaf blower and lawn mower have batteries as the power source.”
same here.
Last summer I bought my first battery operated outdoor power tool. A Stihl battery operated hedge trimmer.
I upgrade to the most powerful battery available for that series of power tools. The battery alone was $100. It is the size of a motorcycle battery. The first time I used it was over 2 1/2 hours. It still had power left. Second time, same story. I probably will never buy another outdoor gasoline engine tool.
However, I am not throwing out all my 2 cycle & 4 cycle engine machines I already own until they die:
Stihl Leaf blower(1999)
Stihl straight shaft brush cutter(1995)
Stihl Chainsaw(1990)
Echo curved shaft trimmer(1990)
Echo straight shaft trimmer(I got this free at the transfer station)
Toro 16” snow blower(used to belong to my Mom)
Honda 4 cycle 20” snow blower(2001)
John Deere 15 HP riding mower (1999)
DR 10hp 4 cycle chipper(bought used at garage sale $400)
Troy built 48” sickle bar brush cutter with 5 HP 4 cycle engine (bought used at garage sale $50)
Honda 7500 watt Inverter generator(2009)
