Reworking the DS / DS RTC chip
I used an iron file that was about the exact width I needed and just fatasheet went back and forth about 50 times until I saw the metal and then used sandpaper the rest of the way. Datawheet with the hot glue. You can see the result here sorry, the text is in french: Don’t ever solder directly on a coin-style Li-Cell. For anyone who attempts this mod My old computer has been out of action for months, but this week I got it going again by following the instructions on your webpage “Reworking the DS RTC chip”.
Worked like a charm rs1287 would like to thank you and I am very grateful I stumbled on your web site. Now the battery is dead, configuration is lost after relatively short time again and you get error-codes constantly. A really new, fresh and unused chip is hard to get.

Thank you very much for putting this mod on your web site. There are no provisions for one. I appreciate it greatly. It works like a champ! These are intended for short-term use with strong charge and datsaheet intervals – not for long-term storage with a comparatively small discharge rate. The only things you need to do is: All described modifictions apply to this chip as well. Have a look at the graphics below. Can you imagine my amazement and relief when I discovered your web site describing the DS rework process.

You did a great job! So you have my thanks and gratitude for putting that idea on the web. Curiosity killed that cat.
It won’t do it no good and may result in early death of that part due to excessive internal heating. Datsaheet dougnflo [at] comcast [dot] net Kalamazoo, Michigan, U. I just want to tell you that I succesfully used your DS rework How-to. On January, 7th, Emmanuel Da Piedade emmanuel. If you have a multimeter test the voltage on pins 16 and 20 before and after. I discovered that the RTC chip was dead. The daily self-discharge rate on some rechargeables is higher than the current taken by the RTC.
Then circumstances kept me from working with it until now Possible Results Reworked chip inside a Mod. Most likely you won’t get a wire soldered properly to it. Soldered and used a CR battery with holder on top of the Should work like a charm.
Note the battery holder! The 0V-reading tells you that you successfully disconnected the battery. Even its successor DS is pretty hard to get and darn expensive.
William Walsh did the DS-Rework to get an external battery to it as well. On March, 23rd, Chris xrisl [at] yahoo. Incidentally, my computer is an Compaq N, which seems to date from about I could not have gotten my Compaq DeskPro e back to clock life back without you!

I used a medium sized flat file Here Best Regards Emmanuel. 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. Attached the two wires to the exposed pins and put the new lithium cell in the holder. At that point you wish you could add an external battery.
The case is usually pretty much “solder-resistive” because of the anti-corrosion plating. It sets too fast! After the dust cleared
