I have a Sears 18 volt cordless drill that is about 8-10 years old. It came with two batteries, and one fails to take a charge. I queried Sears and found that a new battery would cost in excess of $75 with shipping and tax. A new 18 volt drill costs about $74 plus tax. I have been through the battery problem before with another brand of drill, and also found the cost of the batteries was excessive. I am wondering what brands of rechargeable drills some here have found to be good, and the availability and cost of replacement batteries. I also wonder about the shelf life of extra batteries. Would the life be extended of extra batteries if kept in a freezer? I am planning to look at Makita also. Thanks, Jerry Thanks.
