re: Is it too soon to buy a Battery Mower?

I have an EGO chainsaw, blower, pruner, edger, weedeater, etc. They work great and I like using them for my yard (1 acre), but one of my batteries is failing and two don't hold a charge like they used to. Those batteries in question are 3 to 4 years old.

I have to make sure I have all 5 charged each time a do the yard and rotate them on the charger to be safe.

I think the machines are great, but the battery longevity concerns me.
