Kobalt 40-V 4 Ah Lithium-ion Battery for Cordless Tools is rated 3.9 out of 5 by 76.
Rated 2 out of 5 by from did not last long did not hold charge
Date published: 2023-11-13
Rated 1 out of 5 by from Be Ready to Purchase a lot of These After five years of using the Kobalt 40V battery-powered mower, I have garnered a comprehensive understanding of its performance, both the pros and the cons. Here's my take: Pros: Mower Longevity: The Kobalt mower has exhibited impressive durability. Even after six years, it continues to function efficiently. This speaks volumes about the build quality of the mower itself. Cons: Battery Life: The major drawback of the product is undeniably the battery's lifespan and performance. One of the batteries ceased functioning entirely after just four years. For a premium product, one would expect a longer-lasting battery. Diminished Runtime: The second battery's performance is also lackluster. Despite being operational, its runtime has been reduced to roughly 20 minutes for the last three years. Such a short operating time can be quite limiting, especially for those with larger lawns or if you're aiming to complete your mowing in a single go. Cost Implications: Battery replacements are not always cheap. The underperformance and eventual failure of the battery not only inconvenience the user but also might result in additional costs should one opt for a replacement. Conclusion: The Kobalt 40V mower itself has proven to be a reliable machine. However, its accompanying batteries have been a significant letdown. For those considering a Kobalt mower or any battery-powered mower, for that matter, it's crucial to take into account the potential long-term performance and replacement costs of the batteries. In this case, while the mower shines, the batteries unfortunately dim the overall appeal of the product.

Rated 1 out of 5 by from Kobalt 40V Products Junk. Pure Junk. I now have a mower, trimmer. and edger hanging on the garage wall because both batteries have failed after 2 seasons. Go with gas!
