Had my battery powered Bosch for 2 1/2 years batteries are still fine mine are only 2Ah 36V, only need a single battery in the summer couple of charges in full jungle mode, I only have a modest lawn though. It was cheaper to by this mower than replace the Hayter cast ally chassis which snapped on my petrol mower that didn't last 2 years! I went battery as mains cords are a PITA
