I have the same problem with exact same drill. Cannot find any info online.
Have you had any luck in finding replacement batteries?

Hi,
My batteries are now worn out for the same drill. I was going to get the batteries re-furbed but i thought i would just go and buy a new drill. he drill is perfect working order and the charger is still working. Your welcome to make me an offer on this. I'm london based. email me mikeyranson att a.o.l. comm
