Verified Purchase(What's this?)
This review is from: STK's Canon NB-5L NB5L Battery - 1400 mAH for Canon Powershot S100, S110, SX230 HS, SX210 IS, SD790 IS, SX200 IS, SD800 IS, SD850 IS, SD870 IS, SD700 IS, SD880 IS, SD950 IS, SD890 IS, SD970 IS, SD990 IS (Electronics)
Have had this battery for my Canon for a few years, since I bought my camera in fact, and it has worked like a charm. It lasts at least as long as my OEM. Both OEM and this one have been used about equally, swap out one for the other as they die. In fact, now my OEM doesn't hold a charge very long when not in use, whereas this battery lasts long even when not being used, so I always know the back up is there.
