  • Worth it!
Style: 2 Batteries + Charger
Excellent Batteries and a great deal Lowe’s now sells the tools and batteries separately at almost double the cost for a single battery. They last and hold their power well.

  • Great product. The 4.0Amh battery is super strong and well made.
Style: 2 Batteries + Charger
I always love Craftsman products. I keep buying them for years even when sears own them. These batteries are very good. I can use them in all my craftsman products. The charger is awesome. It charged my battery in 2 hours. The 4.0Amh battery is super strong and well made. I really like how you get 2 batteries. Too bad it doesn't come with a storage bag. They use to come with one but not anymore. Amazon is cheaper than a big box store price. Highly recommend. ... show more

  • OEM Batteries - Received 2024 production date sealed new. Charge cycle lifespan TBD
Style: Single Battery
Wont start with a 5 star because I cant say how long they will last. Received 2 new in clam shell sealed batteries as shown in the product listing. Batteries stamped with a origination date of 2024. Most batteries dont last more than a few years in active use. They still had a 2 bar storage. So shelf sitting little to no power loss awaiting a new owner from the factory. Bought to replace a lost battery for a 2 pack tool set of a driver and drill. I will update in a few months once I have put some charge cycles on them to evaluate performance and charge retention. Easy to use lock in place battery system like many tool makers today. Compatible with my OEM Craftsman 20v cordless tools. ... show more
