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

I purchased 2 of these batteries. I have been using one mostly. The second I used as a backup battery. It has been charged three times since I purchased it in November last year. On the third charge the charger was giving me the error that means the control board in the battery is faulty. The other battery I use as my main battery is still working so that is why I have mixed feelings about it. I was charging all of my batteries in preperation for what is now hurricane Dorian since these have a USB that you can power other devices.
