I am having problems with my 18v porter cable cordless drill. I have had it for two year and have rarely used it. Only used one battery. Now I am unable to charge either of the batteries. They are lithium. Not sure if they can be left uncharged for long periods? One battery was flashing red light, which according to code on charger means the battery is bad. The other had no indication at all on the charger. Is there a fix or do I know need to go out and buy new batteries? Since I rarely use the drill motor should I buy Ni Cads instead of the Lithium ones?

Do you work for Porter Cable ? If uou don't use your battery often enough that it discharges just shell out 70 bucks a piece since they haven't fixed the problem with the product? It's super easy just pull the case apart check voltage if it's low use a AA connect + to + and - to - with jumpr wires a few seconds to get enough charge that the battery is recognized. Battery acid is bad so don't open the case with a grinder or axe. Do you work for Porter Cable ?
