These are not in front of me, but I know they are made up of two Lithium=20 Ion Cells of 1000maH (I think!) capacity, so it will charge to 7.2V at 1AH. They were designed for a=20 prisoner anklet, but these were never installed. I have at least 10. I=20 paid $28 each at the prototype level, as they were made in the USA. I'll=20 take the best offer after a week to any PIClister; you pay me +=20 shipping. These things have a 3-pin locking 2.54mm connector, and are=20 still in their swaddling clothes (packaging). I'll post a Jpg tomorrow.=20 They are about 3 years old. Price is very negotiable. NOTE: these do NOT=20 have a built-in protection circuit, so your charger needs to KNOW its=20 Li-Ion and properly charge for that chemistry; the third pin carries the=20 thermistor input (10K@25C) for the smart charger. I am in Tucson, AZ. And... yes, I have guns, but I didn't do it. I am cleaning out my stuff; there will be more stuff, such as my=20 original Intel 8008 Manual.
