I bought two 12v batteries to replace my Dewalts from Amazon... Still working and holding charge ror months..
I would agree if I hadn't already bought 2 dewalt replacement batteries that failed. So at this point the Amazon batteries either work or I go Makita. So far no Makits...I always stick with the manufacturers batteries. The cost more but always seem to last and have proven quality. It is worth the extra money to me. I do not own any Dewalt cordless tools but have many Makita cordless tools and batteries that have always been extremely dependable and long lasting.
