I can not find out the difference between the two batteries.
I suggest you phone Canon service before substituting a different battery.
Canon's pricing is the same for both batteries.
I recently purchased a Canon Powershot ELPH 150 IS. This is the first time I've purchased a camera that does not take AA batteries, but instead uses rechargeable battery packs.
I'd like to get a few more battery packs so that I always have a fully charged battery when I need it. The battery that came with the camera is a NB-11LH. However, in looking through Ebay I'm seeing NB-11L (without the "H"), which appears similar.
Are the NB-11LH and the NB-11L interchangeable, or should I stick with the NB-11LH since that's what came with the camera?
