I've had a corded electric lawn mower for 5 years and I am very pleased with its performance and value. However I am not pleased with the "chain" of the cord. I do not live in the suburbs, I live in the city and do not have a large lawn, so its only annoying for about thirty minutes worth of lawn which I just live with. I am considering a new electric with batteries but herein lies my question.
I live in the north east and I only need to mow the lawn maybe three months our of the year. The rest of the year the mower and its batteries will sit idle in an unheated garage. Will the lithium-ion batteries go flat and not recharge after sitting idle though the cold winter? Will I have to constantly keep them charged wasting money?
I realize I will want to get at least 2 batteries and I'm fine with that investment if its going to worth it. I don't want to have to replace them each year.
I wanted to ask other people who live in similar climates what their experience was before cutting-the-cord, as it were.
Update: Thanks to all the responders for your expert responses. I maybe posted on the wrong forum tho, because I was looking for people who've actually lived it and done it and not so much theory as to how it "should" work or lessons about batteries. Thx.
