Review: working well - takes a charge and powers my drill at a significant cost savings.
Review: Great price batteries got my old saw back in action... - I have several older Hitachi cordless tools- two circular saws, and a grinder. They're nothing fancy but are great to leave in my truck tool box for a quick cut at the lumber yard etc. They have been out of service for several years since the original batteries won't charge. These new batteries seem great- I haven't pushed them hard, so the longevity remains to be seen. I'll update if anything changes but for the price, if they last a couple years, they're an amazing deal.
