Bests & Worsts Reviews from Amazon

I live in a place where we mow our lawn all year and bought this mower a year ago. The machine itself is solid - it mows the lawn well. The problem is the batteries - and this problem is huge. Buried in the depths of the manual is a warning - the batteries do not have a charge management circuit, neither on the battery nor the charger. This missing circuit - which is common in almost all modern battery charging - means that you have to watch your batteries when they charge and immediately remove them when they are full. Fail to do this and the batteries rapidly and permanently lose their ability to hold a charge. How severe is this problem? Well, we have a moderately sized yard, about 1,500 feet of grass. For the first two times we moved, the mower easily finished the job with charge to spare. The third time we ran out juice before we finished the yard. A year later and the batteries last about 100-150 linear feet. Replacement batteries cost around $125 each and come with the same charging issue - miss taking them off the charger once and you'll ruin the battery permanently. Try to imagine another device in your life that is ruined if you leave it on the charger overnight. Doubt you can think of one, and that's why Greenworks cutting costs by removing a charging management circuit is baffling - unless of course that's part of their strategy to sell more batteries. Having used this machine for a year, we're now switching to a different, well known, brand that features batteries that work in all our power tools. In summary: If you don't mind watching your batteries like a hawk while they charge, this mower will work for you. Otherwise, find a different brand.
