My Stihl battery operated hedge trimmer was $199. The battery and charger was another $100.
The battery fits all the other tools in the Stihl series. The only thing I have done to maintain it since purchase is lubricate the blades.
I have 8 small gasoline (4 cycle & 2 cycle) engines pieces of power equipment and a diesel 36HP tractor. I may never buy another 2 cycle piece of equipment again.
Me either, I have many battery operated power tools just now trying to consolidate on one battery brand. Not every tool I want is provided by one company unfortunately. I am in no rush to get into a battery powered car.
I just used my 80 volt chain saw. battery would not recharge as too warm in the 95 temp outside so had to take it inside by the ac vent to get it cool enough to recharge.
