Excellent and cheaper version of canon battery,
Amazon Verified Purchase(What's this?)
This review is from: Power2000 1200Mah Lithium Battery Replacement For Canon NB-10L Battery (For Canon SX40 HS Camera) (Camera)I own three of these "generic" brand NB-10L batteries. So far, so good with no problems. I purchased the new Canon SX40HS camera a few months ago and wanted a spare battery or two for long day trips that may keep me from my charger until later that night (or the next day or two). I'm sure the specific/actual Canon batteries are great, but for the costs, I just couldn't justify speading so much money on just an authentic canon battery. These work great and hold a charge just as long as the canon battey does. I haven't seen any scientific lab testing comparing the two brands, but my experience has been very positive.
I haven't seen any "generic" wall chargers out there yet, so I went ahead and purchased the authenic Canon battery charger for their NB-10L batteries......no problems with compatibility between the canon charger and the "generic" brand batteries. Everything works just fine. The generic brand charges up to "green" status just as quick as the authenic canon batteries does......within a few hours.
Unless someone can show me some conclusive data that the actual canon battery out-performs the "generic" brand by a large margin, I'm sticking with these for the future. Also, I won't beat myself up if I accidentially misplace or lose one of these $15 batteries.
