Wouldn’t charge and completely dead. By the time I went to use it I had just missed my 30 day window to exchange it. I tried to save money but obviously realizing now that it’s better to by the original batteries and not aftermarket. Review: Not useless, but close - Sometimes you get what you pay for. These off-brand replacement batteries to fit Rigid tools are just that. A great price - $50 for two 6.0 Ah batteries. These sell from Rigid for $120 -$140 EACH. I got a set of two batteries, charged them fully and used them in several different Rigid tools. From the start they were weaker, acting almost like a battery that was about discharged. They also did not last very long before needing a recharge - we figured they worked about the same as a 2.0 Ah Rigid battery. So we did a test with a Rigid fan. These 6.0 Ah batteries lasted slightly longer than a Rigid 2.0 Ah. I figure they work like they are 2.3 Ah. But that's with them being brand new vs a year old Rigid battery. We also had a problem where the battery contact points would not touch in about half of our tools - so the tool would not work at all. Not sure why this is although it looks like the metal contacts may be just a touch thinner. Overall performance is not good enough to justify using so they have been returned. ## Features - 【Battery Details】Battery Type: Li-ion battery; Voltage: 18V; Capacity: 6000mAh/6.0Ah; Wattage: 90W - 【Applicable Models】18V Lithium Battery is replacement for all Ridgid 18V Lithium-ion cordless drill tools.
