Ok 1st of all it does run my Kobalt lawn mower without an issue. Sadly it doesn’t work when inserted into my weed eater or the leaf blower. It stops after 5 seconds and you have to release the trigger and it will start again. Over and over again. I’m guessing maybe it has an over current sensor that kicks in on those devices I don’t really know. If your buying for a leaf blower or weed eater look somewhere else.Updated review :The manufacturer did reach out and wanted to correct the situation and sent me a new battery. The new battery is flawless and now works in all my devices. It’s great to see a company who backs their products and stands behind them. I highly recommend.

The Kobalt OEM 4.0 AH battery seemed to be losing it's stamina. Bought this unit. It actually fits the charger and tools better than the OEM battery. Only used once so far and not for a long duration. Jury is still out on how long the charge lasts.

This statement is far from the truth. 4X would mean 160 minutes, because my Kobalt 40V 3.0Ah battery run time was 40 minutes.Battery Specifications】Type: Lithium-ion | Voltage: 40V | Capacity: 6000mAh | Watt: 240W | Pack: 1 Pack,Delivers up to 4X the run time than Kobalt 40V 3.0Ah battery. .i purchased this battery for my Kobalt electric lawnmower. The Kobalt battery last about 40 minutes but it takes me an hour and 20 to cut my lawn. Figured this battery would be the answer, fully charge them both and then i would be able cut full lawn during one cuttings. First 3 weeks perfect plan but i started to notice the battery was not lasting as long. Once, i thought is was maybe my grass was too high and that may have strained the battery. But all the while, the power was getting shorter and shorter. Went out today to trim the grass, yea i said trim just clip the edges, not hard work for the mower or me, battery lasted 15 minutes fully charged according to the indicator light. finally decided this was not working so i went to return and wa la the "return" had expired. yea not good for me, but its a blessing for you. Because if i had returned it, i most likely would not have written this review. So i say again, do not purchase this battery.

It was a perfect fit for my 40v Kobalt lawnmower . The price wasn't outrageous either. It came with a charge, but waiting on my charger to give it a full charge. Would recommend.

I had seen mixed feedback on these batteries, suggesting that they might not work with older Kobalt tools because of slight changes in the battery design. Received this battery yesterday, charged overnight and it worked fine in my Kobalt KM 2041B-06 mower (40v, 20-in deck) from 3-4 years ago.The battery does not last quite as long as my OEM 6MAh battery, but for the price it's a good value and provides plenty of extra runtime to get through my larger lawn. I'll try to remember to update at the end of the season on how the charge holds up after weekly usage & recharging all summer.

The battery charges and runs exactly as it should.

Needed to buy a replacement battery pack for my electric lawn mower and this works great, and a bonus cause it actually last longer then the original equipment.

Frustrated with the short battery life of our Kobalt push mower and reading that those batteries only only meant to last a couple of year, I wanted a backup. Lowe’s only had a lower AH in stock and they were super expensive. To match the 5.0 of our original battery, it was out of stock but listed at $185, most than half cost of the mower. Yeah, no…This battery doesn’t come with a charger but it does fit in the Kobalt charger. No issues with charging or using. Being 6.0 I think the charge is supposed to last slightly longer than the 5.0 but my son has been the only one to run down the new battery completely. I just use it for small jobs, but don’t notice any performance issues (besides the lawnmower not being awesome but that’s not this battery’s fault).Very happy it works with the original charger and fits perfectly so it’s 100% interchangeable with the OEM battery but less expensive.Update 2 months later: lowered from 5 to 2 stars. After using once a week, this battery doesn’t last even half what the original Kobalt battery does. The original Kobalt battery you can tell when it starts getting low, this one goes a short time and then just stops completely.I have a 40ftx45ft garden and I mow the walkways between beds. Today the Kobalt battery did 3/4 of it before dying and I did the tallest/worst sections first. This battery only had to do the last 1/4 which should have been easy. Barely finished the garden and tried to do another small section of the yard and then it died. As long as it takes to charge compared to how long it lasts, this is maybe worth $50, definitely not $100+. Very disappointed with battery life.
