Great brand
They are expensive but they last longer than most other batteries. I'm a woman that loves tools and getting my hands dirty so I always look for things that are worthwhile. They charge pretty fast and hold the charge for a while. I have a very large backyard and 2 of these in my lawnmower get my entire yard done. I will be sticking with Dewalt and HyperTough products from now on.

Right fit
Recently bought a lawnmower with the 6.0 Ah batteries. Wanted a back up set of batteries to be able to complete our yard. 6.0 AH don't seem to be available so went with these. Work fine and more importantly the chargers that I have from the lawnmower fit %26 work!! Was a little worried about that since a previous Snapper lawnmower had major issues with replacement batteries so Kudos to Hyper Tough to have replacements that actually do the job. I usually pair one 6.0 with a 4.0 and the mower works fine. Nice to have a fresh pair of batteries when I am halfway through the yard. Definitely recommend.

Great Battery
I purchased this battery as a backup. It has performed as expected. I use it for a Hyper Tough hand blower. Great product with long lasting batteries.
