Review: Works Well. - Great battery and last well.
Review: Great battery.. - Wanted more usable time between recharging, my old 2oa batteries are good but you can't tell how much power still available until they run out. These 40A have indicators on them letting you know how much power you have left, I bought a few, some for my power tools, and some I use on my lawn mower ( switched from petrol to battery powered) I have a large lawn and these are capable of gutting my lawn twice before having to recharge. I used to use 4 liters of petrol for each cut before just to give you some indicator over how big mh lawn is.
