I needed an extra battery for my mower, I couldn't finish my lawn with what I had, I would get a third done and it would die. My mower is a dual battery, self-propelled and I knew I needed another battery. So I bought this PRO 60V 6.0 AH HC Battery and now I can do almost my entire lawn before I need to switch over. So grateful I purchased this!
I bought this a couple of months to use in either my 21" mower, or weed eater, or backpack leaf blower. The mower came with a 4.0 ah battery and I could mow my small 1/5 acre lot with one charge, if the grass was not too thick. The last two times using this 6.0 ah battery allowed me to cut the whole yard and still be half charged.
