Review on WAITLEY 18V 5.0Ah Replacement Battery For Makita Lithium-Ion Power Tools - Compatible With BL1830, BL1840, BL1850B, BL1860 Models - LED Indicator Included by Aaron Gordon

The battery works, I have used it for 2 charge cycles so far. My only and main complaint is the fit is terrible. Its a PAIN to get connected or disconnected on all 3 tools I have and the original charger as they don't line up right. Also the release button seems to be poorly made and doesn't work right either. That being said, its less than 1/2 the price of the Makita brand one so I didn't think it would be perfect but other brands fit are way better.
