Then circumstances kept me from working with it until now Note the battery holder! Go with the hot glue. I just want to tell you that I succesfully used your DS rework How-to.

The only things you need to do is: On March, 23rd, Chris xrisl [at] yahoo. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC. Care for the polarity!

I appreciate it greatly. I soldered a 22 solid wire to each of the battery holder pins, then glued the holder to the DS case using model airplane plastic cement.

Curiosity killed that cat. At that point you wish you could add an external battery.

Thank you very much for putting this mod on your web site. Soldered and used a CR battery with holder on top of the Worked like a charm and would like to thank you and I am very grateful I stumbled on your web site.

Most likely you won’t get a wire soldered properly to it. Don’t ever solder directly on a coin-style Li-Cell. So you have my thanks and gratitude for putting that idea on the web.

Howe dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. Attached the two wires to the exposed pins and put the new lithium cell in the holder. My old computer has been out of action for months, but this week Datashwet got it going again by following the instructions on your webpage “Reworking the DS RTC chip”.
