Review on Power Up Your Tools With 3.0Ah 18V BL1830B Battery Replacement For Makita Lithium-Ion Batteries With LED Indicator by Michael Hudson

I have a Mikita cordless screwdriver. Battery fit nice and snug. Charged without incident. Problem, however, was that the screwdriver clamp that locks the battery in place was almost impossible to place over the battery. If the clamp was forced onto the battery it needed (considerable force) to be pried off with a screwdriver. Solved the problem by just simply shaving the battery plastic (sharp knife) where it locks/holds the clamp until the locking/removing process required only a reasonable amount of force. Just took several minutes, hope this helps someone.
