Unfortunately, the BP-511 equivelent is exactly equivalent and only
delivers 1100 mah (like the Canon original) instead of the 1390 mah of
the BP-511A or the 1500 mah of some more modern cells. That may lend
some credence to my musing that perhaps Maxell had been building the OEM
batteries all along.
