Unlike other replacement batteries for Kobalt 2540C-06, this one actually fits and seems to work great.

Batteries work great. I have 2 for my Lowes Lawnmower. 10/10 for customer service. I had one battery die at 9 months and they held up to their warranty and replaced free of charge. The batteries work great. Good power and have just as much power as the Name brand.

I bought this item to replace a failing battery in my Kobalt lawn mower. That 5 Ah battery, when new, would run for well over 45 minutes, long enough to cut all my grass in the front and back yard. Recently though it's been going bad, and now won't run longer than 20 minutes. I bought this battery as a replacement in the hopes that I'd be able to restore my mower to its former performance. Unfortunately after charging the battery to full and starting my lawn, the battery only ran for about 20 minutes before dying completely. I'm extremely dissatisfied with this product, and I will be returning it immediately. You get what you pay for.

just used one time, after fully charging.. didn't seem to last as long as I hoped.. about 40 minutes. May be returning it if it doesn't perform better the next time.. while recharging it just went to 2 lights when it should have charged completely.. took it from charger and then back.. it started charging again and showed all the lights (fully charged).. will see how it does in a cpl of days.

I compared this 6.0 AH battery to a 4.0 AH battery that I ordered at the same time for my 40V Kobalt Leaf Blower. I cannot tell any difference in the power, and it does not last longer than the 4.0 AH battery, and during the Black Friday sale it cost $12 more. Of course the battery is back to full price now. It is not worth the extra expense. It did fit and work with the Kobalt Leaf Blower and Charger.
