High-quality replacement for Canon's NB-1L battery. Guaranteed compatbility with all cameras that use the NB-1L battery incl DIGITAL IXUS 400 v v2 v3 PowerShot S100 S110 S200 S230 S300 S330 S400 S410 S500Customer Review: Power Pro batteries
So far so good. These batteries perform well and they were very cheap. The other reviewers are right that the shape is slightly different, but I'll deal with this to save $40.
Customer Review: so far so good
so far so good, but the size is a little bit large, 1mm more compare to my canon orignal one. It can just fill into the slot. However, it is so cheap!!!!!
