Review on Power Up Your Tools: Get Waitley'S 2-Pack BL1850B-2 18V Replacement Batteries With LED Indicator by Eric Smithlin

Charged battery twice, now has failed completely and will not recharge. They fit, but poorly in Makita charger. I am now contacting company in China for replacement or refund. I did get a refund for one battery. Easy and fast. Other battery is still working. Only charged once. Follow up. Second battery has died. Charged maybe 5-6 times total. Never let charge on battery run down completely before recharge, usually recharge at 40%. I will not buy again. My original Makita batteries are still working. I will buy Makita made batteries for the quality and reliability.
