Exactly what I needed—having two batteries makes life easier
Style: 2 Batteries
Sometimes there's just not much to say about a product because it does exactly what it's supposed to do, and that's the case with these batteries. I purchased the 2-pack as backups for my CRAFTSMAN V20 tools, and they fit and worked exactly as expected. There was no complicated setup or anything unusual to deal with, charge them, put one on the tool, and get to work. What I really like about having two batteries instead of just one is the convenience. I can keep one charged and ready to go while using the other, rather than having to stop what I'm doing and wait for a battery to charge. If you're using cordless tools regularly, having a spare battery on hand is one of those things you don't fully appreciate until you need one. The 4Ah capacity is also a nice option for anyone who wants more than the smaller batteries, although I haven't done any formal testing to determine exact runtime. In normal use, they've performed as expected and have given me no reason to complain. They're genuine CRAFTSMAN batteries, they fit my V20 tools properly, charge as they should, and work as advertised. No surprises, which is exactly what I want from a replacement tool battery. If you already have CRAFTSMAN V20 tools and need additional batteries or simply want backups on hand, this 2-pack is a practical purchase. Sometimes “boring and works exactly as described” is a pretty darn good review.

Great size and perfect fit. Great performance and excellent quality. Highly Recommended.
Style: 2 Batteries
This two pack of batteries is just what i needed. I had purchased 2 fans to use in my business and for use in my side by side when out running around without any AC in Texas. These batteries fit the purpose perfectly. I already had a craftsman batter charger and just wanted a couple of new batteries as most of mine are over 5 years old. These new batteries charge really quickly and even faster than my old ones, but is likely due to the age and use of my old batteries. These batteries run all my drivers, impact, drill stools, and vacuum and blowers as I use a ton of DeWalt batteries and using an adapter from amazon these run my DeWalt just as well. Excellent charge life and performance making them last longer than my old batteries and with the adapter they run all the tools i have. very simple to use and charge so I would highly recommend this pack.

Love these
Style: 2 Batteries
Good size for the drill and impact. Also runs a small weed wacker for about an hour. And more than long enough blowing time with the little leaf blower when using it on the deck and patio.

Overall Not Bad
Style: 2 Batteries
I used these with my weed trimmer. The only downside I see is the continuous use for me is between 30 to 45 minutes. Other than that, I give it two thumbs up. Highly recommend the 40 volt.
