ThinkPad non-OEM batteries?

I have a nice little ThinkPad Edge 13 and it's a great machine, really - amazing cost vs value. I've happily been running it for more than a year (so yes, the basic warranty has expired) and I've attempted to get a new battery for it - which failed in the usual insidious way: apparently the machine won't accept non-Lenovo batteries. This is a big #fail for Lenovo and means that this will be my first and last ThinkPad. ... except if anyone knows how to unlock batteries?


The situation with cell phones locked to carriers is bad enough, but batteries? That sucks.

The battery is probably not broken by itself - as I've already exhanged as "malfunctioning", but Google finds numerous complaints that Lenovo (at least for some markets) ships with laptops locked to OEM batteries.

I always thought there's an EU prohibition against it?

My plan is to rebuild my pack. The cells which populate a battery pack are going to be quite standard lithium ion cells; these can be obtained with tabs pre-soldered on to them (never try to solder tabs on to these cells on your own). For those who have some soldering expereience and good electronics sense, self-rebuilding is an option; for the rest, at least in many major urban areas, service companies which do this work can be found.

I'm extending the life of my pack by setting the firmware to charge the pack only to 85%. Avoiding full charge can *double* (or more) the life of li-ion cells. I find I still get plenty of runtime. Avoiding full charge is the number one thing you can do to get the most life out of your cells.
