Got it as a backup battery for my Kobalt lawn mower. It seems to do the trick. Mowed the whole lawn with it.

    • Doesn't hold charge
Battery does charge however it's capacity is less than 1ah and discharges after a few min of use... Faster than another 1ah battery we have.

    • Works so far
This battery seems to work just as well as the original batteries do. It holds a charge as long as the original ones do and seems to be just as powerful. No complaints here but I'll update if things change.

    • Excellent Replacement Battery
Save your money - don't buy the brand name battery for a spare or secondary battery. This battery comes at a lesser cost and has the same performance standards as the brand name battery I own. The battery comes three quarters charged, so fully charge before use. The battery fits my hand-held pressure washer and the battery charger. Why pay big bucks for a spare brand name battery when you can get this replacement battery at a significantly less cost for the same performance. ... show more

    • Exceptional Replacement Battery - Outperforms the Original!
I recently got the NEPOWILL 40V 6.0Ah Replacement Battery for Kobalt 40V tools, and I couldn't be happier with its performance. This replacement battery fits perfectly into my Kobalt 40V weed wacker, sliding effortlessly into both the charger and the tool itself. With its 6.0Ah capacity, this battery offers an extended runtime compared to the original, allowing me to complete tasks without frequent recharging. So, it's particularly beneficial for demanding tasks like weed-eating the lawn. This battery also delivers consistent, reliable power to my Kobalt tools, maintaining a smooth performance throughout its use. Despite its larger capacity, the battery charges surprisingly quickly, fully recharging in about an hour. This is nice because with two batteries, I can pretty much go nonstop, swapping and charging. Plus, The NEPOWILL replacement battery offers exceptional value for the money. It not only outperforms the original Kobalt battery but also costs less than the brand-name 4.0Ah battery currently available. In terms of longevity and durability, the battery already shows great promise. It excels in extended runtime, fast charging, and reliable power delivery. Plus, it offers outstanding value for Kobalt tool users, eliminating frequent recharging interruptions. Highly recommended! ... show more

    • Great deal
I got this for my kobalt weed eater. The battery that came with the weedeater was just a 2AH. This easily doubled my working time. I don't quiet believe the 6AH rating, but it's much better than the battery that came with my weedeater. It's a great deal compared to lowes.
