Summary: always good practice to have a second charged camera battery available: too bad Cannon does not standardize the battery for the Powershot camera line: There are many less expensive 3rd party camera batteries available; I have not had good experience going off-brand
Pros: Easy to Install, Fast Recharge, Long-Lasting, Reliable, Solid Construction
