Query: Seemed to work at first but then died

These batteries seemed to be working fine when I initially installed them. (I carefully avoided soldering close to the batteries an tried to heat the battery leads as little as possible when connecting them.) After a few months they started to not hold a charge and now, after a year or so, they don't hold a charge longer than about 15-20 seconds!I'm now looking for some new replacements and you can be sure, I'll look elsewhere.
