The old electric mower finally died. Went out and bought a new electric mower at Lowes. These new batteries are awesome. Did my entire lawn and still had 2 bars left. Bought the variable speed power assist and its perfect for me recovering with a new knee. All my tools are now electric including my favorite the chain saw. All interacting batteries so now I have backups for each device. The ethanol in gas and all the issues with gumming carbs sent me over the edge.
