    I got a Greenworks 40V mower in 2016 that came with 4Ah and 2Ah batteries. The 2Ah gave out after about 6 years, but the 4Ah is still going strong and holds a great charge. I live in Texas and store them in my uninsulated garage. Were you storing them drained? It’s important to recharge them before you store them. Also you might have just had shitty batteries. I got another 4Ah battery along the way as I added the trimmer, blower, and chainsaw and have never had an issue with running out of juice unless I let the grass get too long and try to cut it too short

        I’ve always stored mine at full charge, though granted I still use them over the winter, just less often. I wonder if storing them so long unused harms battery life
