I have an inexpensive Casio with a dead battery. It has been a workhorse and was givien to me as a gift by my son, so for sentimental reasons I would like to keep it going. Don't want to go near the Mall today to get it replaced (Christmas mad-house), but I can buy a battery locally.
Two questions; 1) How do I remove the little clip that is over the battery and; 2) I am supposed to contact AC with Battery+ with tweezers. Where's the AC?

Thanks in adavance for your help.
