    Hooked right into my Kobalt 40V Backpack Sprayer and I was right back to work. Definitely lasts longer than my warn out OEM battery pack. I feel like all the ratings are these are theoretical maxes and not really what you are going to see when you actually use. I don’t know if OEM batteries are rated differently. Generally usable battery capacity is actually 80% of what the cells are rated for. This battery has got some weight to it so I believe its at least got the capacity of the lower rated OEM. Price is much much better though. If it starts acting up I will probably tear it down, check out the actual internals and update.

    When I was a kid, my dad would always emphasize the importance of having a full can of gas before you started a major yardworking project. Back then, everything was gas powered. Today, most quality power tools are battery powered but the lesson remains as valuable as ever. If you’re going to have power tools you’re going to need extra batteries and extra chargers. The good news is that you no longer have to pay a premium to get the OEM batteries. There’s now a slew of third party companies making batteries that are just as good as–in some cases better–than the original equipment manufacturer.

    I’d put this Supowill battery into the category of a ‘superior product’. You’ll get longer run time than the OEM 40V batteries and at a significantly lower price point. This will do the job with all Kobalt 40v tools and 40v chargers. I’ve got a number of other Supowill products for my other power tools–they make an excellent battery! Highly recommended!

    This battery was ordered so that I had extra power for my Kobalt battery powered hedge trimmer, grass trimmer, and leaf blower.

    The battery is a direct replacement for Kobalt brand batteries and charges and works just as well. Run time is excellent. I can trim and blow my entire home on a single charge with power to spare (my lawn area is approx 6000 sq ft).

    The battery actually charges a bit faster compared to my Kobalt branded batteries. It also has the same type of battery life indicator that allows you to press a button on the battery to see how much charge is remaining.

    So far this has been an excellent battery option for my 40V Kobalt tools and at a price point that is equally excellent.

    Back in 2016 after a bad storm I picked up a Kobalt 40V chainsaw. Since then I been using it every year many times. Even tho the original battery pack still holds a decent charge, I been wanting a spare battery pack for a couple years. I ordered this one and its perfect for my needs. Fit the charger and charged up fine, and worked well in the saw. 5 star all the way!

  5. Zilacon

    A like-oem designed replacement battery for kobalt tools. Works good, arrived pre-charged, and charges just fine. The battery gauge has a coil whine when activating and seems to go off when nothing is touching it. Other than that its a good battery in power/voltage and capacity/runtime.

  6. Critical Thinker

    Better than the original Kobalt batteries at a lower price. You really can’t go wrong. They fit perfect in Kobalt chainsaw with tons of power.

The performance matches that of the original batteries, ensuring my tools operate at their best.

    This is a perfect OEM fit to my Kobalt 40v tools. I have the Weed Wacker, edger, and the leaf blower. The tools came with a battery rated at 2.5 Ah. The OEM batteries have been sufficient, but this battery will allow me to complete all my yard work without having to swap out batteries. Being a longer lasting battery, I could immediately tell the difference in weight from my OEM batteries.

    The battery came with about a 75% charge on it, so the first thing I did was slide it onto my charger. It had the grooves like the OEM batteries and easily slid on the charger. It reached 100% charge fast. I put it in my leaf blower and gave it a test. Fit the tool perfectly, delivered the power that I expected, and I barely used any of the charge. This battery in heavier than the OEM battery, but it was barely noticeable in the tool.
