Canon NB2L Battery Pack for Elura 40MC/50, Optura 400/500 Camcorders & S30/S40/S50/S60/S70/Rebel XT Digital Cameras

So far so good. The item was as described and functions flawlessly with my camera. This seller does a great job of fulfilling the order quickly.I will follow up if, and only if, I start to have problems with the battery holding a charge, etc. But so far, I have charged it once, run it down and then charged it back again.

This is a proprietary battery almost exclusively for the Canon Powershot S-series (S30/40/45/50) line of digital cameras. If you don't own a Powershot S-, this is not for you. If you do, read on...The Canon Powershot cameras were designed to be powered by a proprietary battery - the NB-2L Lithium Ion - and cannot be powered by standard disposable or rechargeable batteries/battery packs. So if you want a spare battery, the NB-2L is it.DO YOU NEED AN EXTRA BATTERY? Most digital cameras eat up battery power quickly, especially with the LCD on, so even the casual photographer could find a use for a second battery (e.g. if you are going out for the full day and don't want to get stuck with a dead battery in the middle of junior's baseball game).WHICH ONE SHOULD I GET? There are only a handful of other manufacturers that make a compatible NB-2L and from what I've seen you're bound to save maybe a 10 spot at the most over the Canon. In one sense, a battery is a battery is a battery - if it has the same voltage and amp rating, there probably won't be significant performance differences (no, the bunny doesn't go longer on the Energizer than it does on the Duracell - that's marketing, sorry to burst your bubble). So by getting the Canon you pay a little more for the same product but maybe get a little peace of mind that you have the same battery as originally came with your camera.But wait, there is one other option. The Canon and most other NB-2L batteries are rated at 7.4 volts and 570 mAh. The volts measures how much power at one time the battery delivers - this has to be standard so your camera will not blow up. The mAh, or milliamperes per hour, measures the total storage capacity of the battery. There is one manufacturer out there that makes an NB-2L that is rated at 650 mAh, thus suggesting you will get 14% more life out of this battery than the Canon (I'll be nice and not mention where to get it, but search the web - you will find it). Whether this holds true, I'm not sure as I'm not an electrical engineer but maybe you are, so it's one option. To be fair, I bought the Canon cause I have a low risk tolerance and I like to see the Canon name on my battery.BOTTOM LINE: A safe bet if you need a proprietary NB-2L for the Canon Powershot cameras - you'll only save a few bucks maybe with a third party battery.

I hiked the Grand Canyon, visited Vegas and wandered around Arizona...then returning to the freezing wastes of NYC.You really really need the extra battery if you're travelling. I had two battery packs for my Canon S40 and I would recharge them at night in the hotel - keep one in the bag and the other in the camera and usually about half a day (8 or so hours depending on useage) I would have to change it. Sometimes I wouldn't need another battery for the whole day.Buy an extra battery - it keeps you functioning smoothly and usually recharges in 30 minutes.I didn't seem to have any issues with the temperature variations either.I would suggest you also buy an AC Adaptor -- just to make life easy while uploading your pictures.

I use the NB-2L from Canon with my S45 and I also hve some aftermarket batteries. I am surprised that the canon isnt lasting a lot longer then the aftemarket batteries. Dont get me wrong it works ok but not sure it is worth spending a lot more to get the canon

Got this a defected one, never get charged, the charge light went off right after plug into charger. The same one I bought with camera works fine all these years, ~ 5-6 years. But not this one.

Price point was good but these batteries do not hold a charge for anywhere near as long what my "branded" Canon batteries did. The manufacturer's claim that these batteries meet the Canon original equipment requirements is COMPLETELY BOGUS!As a battery goes, I'd rate it a 1 star but due to the price point I can have three of these as backups for the price of one Canon battery so I have rated it a 2.star

Prior to purchasing this battery I bought an off brand battery to save money. That was a mistake, the off brand did not hold a charge. This battery works well and held a charge even when we were in the cold for many hours and took several dozen photos. Very pleased.

So far the batteries are working great! I bought off brand as backup batteries when I first got my camera and they didnt last as long as the Canon brands that came with the camera. From now on I will only purchase Canon brand.
