Query: No Power

I bought the firestorm circular saw because I already owned the 14.4 Volt drill (which is a great product). The design of the saw is good. It is easy to make straight cuts. The flaw it the saw is the lack of power. The battery runs down quickly. The battery dies after cutting about 12 feet of 3/4 inch partical board, then needs to charge for 3 hours. Luckly I have two batteries which came with my drill and the one which came with the saw. Even so, I am unable to complete a project without long delays charging batteries. The engineers who designed this saw were not thinking too well when they coupled it with a 14.4 volt battery. Were they intentionally trying to jip me or were they just stupid. The saw would be just fine for cutting a board or two, but running out of power every five minutes is a little lame. I will nowhave to go out and buy another saw just to complete my project. I'm very disapointed..
