voltage of 9114B disk drive - Gonzalo Fernandez (Spain) - 09-25-2008 I would like to bypass the battery and associated circuit in the battery plastic case. What DC voltage and current should I feed to the 9114B battery pack (with the innards removed)? A transformer that supplies 6V DC with 2A current?
thanks

Re: voltage of 9114B disk drive - Garth Wilson - 09-25-2008 Does it take the same battery pack as the Thinkjet printer? When my battery pack went out and I saw what they wanted for a new one, I wasn't about to pay their price. Until I could make my own power supply, just for kicks I put a 9V battery on there. It worked, but after about six full pages the battery could no longer deliver enough current, even though it was still virtually new for other applications. I made a 7.8V regulated power supply. It cost me fifty cents. I had everything I needed except one of the diodes, and that diode was fifty cents. I used the printer with that power supply for many years.
Re: voltage of 9114B disk drive - Diego Diaz - 09-25-2008 Hi Garth, To your question, the answer is no. Thinkjet printer battery pack is build usng 6 NiCd in series (7.2v nominal) of the same type you can find in any 41/71 peripheral battery pack. Batteriy packs for 9114A/B use a 6v Lead-Acid batery. Cheers.
Diego.
