sometimes it's just a battery that has sat on the shelf for a long time (these phones are years old, so the battery probably is old stock) get out your multimeter and measure the voltage coming from pins 1&4 (I think from memory) if it is less than 2.2 then you can't get it to charge. I use a 9v rectangular battery and connect 2 wires up to the battery and then the pins to give it a "boost" for about 30secs then it should charge.
