I’m a bit leery about buying off-brand batteries. Sometimes they work well, sometimes they’re junk. But with a replacement Canon NB-9L battery running 74.99, yikes! That’s nearly half the price of buying a new mid-range Canon Elph camera!
So I think I’ll take my chances with a no-name equivalent battery for, get this, $7.83. For that price, it’s certainly worth trying.
