Query: These are old, with a short recharge life, end of the era.

It was because I could no longer obtain good quality BL-5C's that I finally gave up my Nokia phone.I think the last battery I tried in it was one of these, it actually had worse performance than the battery I had used for a year and was trying to replace.These might be phonies from China or just so old that they are chemically inert, but I am afraid I can't recommend these.
