Review: I got this battery to have as a backup for my Kobalt 40V battery. It's great to have an extra, so I can use two items without having to switch the batteries back and forth. It seems very durable and pretty much identical to the name brand one. Obviously this one is at a much better price. It's a great value! It fit perfectly into my kobalt tools. Battery quality and capacity seems very similar to my name brand one. It also charged right up with my Kobalt charger. I've used it / charged it a handful of times now and still working well.
Review: In my experience, I have been able to do more extensive outside tasks, such as pruning hedges and clearing brush, without having to stop in the middle of the process to recharge my batteries. I used to have to replace batteries or take pauses to recharge, but now I am able to perform the same chores in a single sitting. Because of this change alone, my weekend tasks have become more streamlined and productive, and the irritation that I had as a result of interruptions while I was working has been eliminated. Using it on my cordless trimmer, leaf blower, and chainsaw, I have found that it has worked reliably without causing any performance degradation in any of these tools. This battery was able to keep everything going for a longer period of time than was anticipated, even when used with more demanding items like the chainsaw, which typically consumes power very rapidly. This consistency makes a significant impact for someone who regularly changes between tools while working on the same project. In spite of the fact that I had anticipated that it would take more time due to the bigger capacity, I discovered that it charges within a decent amount of time and is ready whenever I want it. After I have finished a job, I will typically plug it in, and by the time I need it again, it will have been completely charged and ready to take action. Due to the battery's dependability in ensuring that it is always available for use, the stress associated with planning around charging schedules has been eliminated.

*by M***T on 20 November 2025*

Bought this as a gift for my son in law. He said it works really well in his electric mower and a lot less costly than the name brand. He told me it charges well and holds the charge long enough to cut his 1/3 acre yard.
