Okay...you recover old cells from laptops. Fine. Been done by lots of people. Actually some chargers are rather small but whatever makes your day. In your post you didn't mention any of what you said related to your cycling. Personally when I ride if I'm using torches I want to use my newest / highest capacity cells. Of course if you carry along a bunch of older back up cells I'm sure that can work as well.
