Just received these batteries today and find they will not fit the Craftsman charger. In fact they got damaged when trying to plug them into the Craftsman charger and the charger blinked that they were defective. They may look like craftsman batteries, but they are not a replacement in any way. Reading the return policy says that I will have to pay to ship them back and if any damage is reflected I will not receive a refund.
No refund guarantee. Stay away from this company. I am VERY unhappy and will definitely warn any of my friends and family about this product and company. As if, I have money to throw away.
