Replacement for Kobalt 40V Battery 6.0Ah, New Upgraded 5X Longer Runtime, Compatible with Kobalt 40V Cordless Power Tool, for Kobalt 40V Max Battery KB440-03 KB2540C-06 KB240-03 KRC60

Came fully charged and popped right in my kobalt 40v lawn mower and cut majority of my yard. Not sure if its a true 6ah battery but sure the hell beats paying over $200 for the name brand one. Only used it once but lasted a good amount of time and charged right back up on my kobalt charger. So far its value is there.

The XAVITO 6.0Ah Replacement Battery is a high-capacity lithium-ion battery designed for Kobalt 40V Max cordless tools, including models KB440-03, KB2540C-06, KB240-03, and KRC60. With a 6000mAh capacity, it offers up to five times the runtime of standard 2.0Ah batteries, making it ideal for extended tasks like lawn mowing, hedge trimming, and power washing.

The Kobalt battery that I needed (the original one was 7 years old) to replace was $249 at Lowes and this one works perfect for only $93. Great deal!

Fits perfectly. Works great so far. 6ah capacity!! Used it for several jobs today and it worked flawlessly. Lasts longer than my kobalt batteries. Great value.

Perfect fit for my electric lawnmower and the battery life is double my original battery.

Battery came charged, ran out after a few minutes use and then would not charge at all. Went with a Saber battery and have had no issues

Fits perfectly on battery charger and inl lawn mower

compatible with Kobalt 40V battery. I used it lawn mower and charged it with Kobalt original charger. see the attached images for reference. The original package is with two Kobalt batteries of 2.0Ah, after 2 years service they are not enough to finish mowing the whole yard. This one is 6.0Ah with the same dimensions, and it is able to do it with only one. Also, it has a power indicator, easily pushing the button will tell you if it needs charging or not.
