I bought the "Frequently Bought Together" link so that I could have 4 CR123A batteries. The charger arrived with the batteries in place. Charged for three hours, the green light never turned off so I put them in my flashlight and they did not work. I put the additional two batteries in the charger and two hours later they exploded, leaking all over my counter and the charger. I have sent them back for a refund. I am look at the Hi-Tech charger for about $55 but it comes with 4 batteries and a USB charging cable. DO NOT BUY THIS PRODUCT.
