I don't know the answer to your question, but I imagine it's the same one used in the HP2225 ThinkJet printer, right? When my battery in the printer went down, first I just used a 9V alkaline battery which only lasted about six pages before it was no longer strong enough to print, even though it still had most of its life left for other things that used 9V batteries. Then I built myself a 7.8V power supply, and used the printer for years with that.
