I don't use my stirrer from the TF-PRO test kit much--just a few minutes per day. I've now had to replace the batteries 3 times in less than a year. Testing the voltages of the used batteries reveals all at 1 volt--so they actually are all drained. Decided to wire up a transformer I had from a micro usb device (don't know which device--probably a mobile phone I once had).
The transformer is 5 VDC, 600 mA. Here is the process (30 minutes):
1. Cut the micro USB connector off
2. Take apart the stirrer (5 screws).
3. Drill holes for cable routing
4. Insert cable (I tied a knot so it would have a "stop")
5. Strip the cable leads
6. Tin the leads and solder onto the battery contacts
7. Re-install screws
Works good--lasts long time. Can still use batteries--just don't plug it in with batteries installed.
