Update by user Aug 09, 2021 They've done nothing to resolve the issue. Every one of the batteries I bought less than a year ago is dead. Nothing compared with OEM parts which lasted for years. They are worthless junk. Original review posted by user Jul 10, 2021 all three of the batteries I got 8 months ago for my Milwaukee 18 v tools are defective. Two will not take a charge and now the third one only works sporadically. batteriesbatteriesbatteries = garbagegarbagegarbage and of course they will not do anything User's recommendation: stay away from this garbage.
