We just replaced our 10 year old electric mower (old battery Kobalt) with a new one. We had three batteries and only recently did we feel their life wasn’t long enough for our nearly half acre lot. Out of curiosity…How old is your mower? Our new mower has self propelled and can do the whole yard with juice to go again. I do feel that you get what you pay for with electric mowers. We went with a mid grade and a reputable brand since we know we will hold into it for ages. I recommend to folks to always buy one that is marketed for larger than what you have if you are gonna hold onto it because batteries degrade normally so it is good to plan for that.
Non-self propelled Kobalt (40v model with the interchangeable batteries). Batteries were also used in a pole saw/hedge trimmer (interchangeable heads), weedeater, and leaf blower. They were definitely used heavily, but not outside the scope of what they were sold to do.
I’ve had that set since 2020. Batteries did fine that first season (juice to spare like you said) did okay the next spring, but by the end of summer 2021, it’d take 3 charges just do the front yard. By the time I’d get everything mowed, I’d have to start all over again.
Yeah. I have a newer Kobalt blower that takes the new batteries compared to the mower we got in like 2014 and it does not perform as well. We intentionally avoided Kobalt for that reason. Plus the blower seems to eat away at charge if you store the batteries in the blower. I now store all batteries loose to prevent draining. Wonder if my experience is related. Do you store the batteries loose or in the mower/blower/weed eater?
I charge them up and then keep them on a shelf in the basement. During the winter, I don’t top them off.
Pretty sure the only thing the manual said was to not store them in the charger.
