I AM VERY PLEASED WITH QUALITY. WORKS LIKE ORIGINAL KOBALT BATTERIES.

Time will tell, I haven't yet given them a workday's trial much less a test over time. So far, have charged up and powered my equipment. Will they hold a charge over time ? Or self discharge. How will they hold up to heavy use ? It will take a few mo ths to find out.

What I wanted

I knew these were smaller than what I typically used, but I decided to give them a try because they were inexpensive. Tey would be better suited for a small hand tool and not a weed eater or blower. The charge doesn't last very long.

Only used a few months but so far work better than the factory batteries.

One battery in my set failed well within the advertised 18-month warranty. Their listing clearly states they will provide a replacement or full refund according to the customer’s preference. When I contacted them, that policy was not honored. Instead: • They sent me to Amazon knowing I was outside the return window • Later admitted they didn’t expect Amazon to help • Changed the terms of their warranty mid-conversation • Claimed the policy only applied in a more limited way than what’s written • Offered only a partial refund There were no disclaimers or gray areas on the listing. The terms were clear , until I tried to use them. Amazon ultimately resolved the issue, not the seller. If you’re relying on their 18-month warranty…don't. Typically a policy is a vow to customers and customer service, here its a marketing tactic to push the sale.

These batteries work with all my Kobalt power tools and are half the price as the ones from Kobalt. I've been buying these for the last few years and only had one go bad in that time.
