Digital camera reviews of CTA Digital DB-NB4L Replacement Battery for Canon Digital CamerasDigital camera Review: Battery - DOA Summary: 1 Stars
When I received this battery I immediately tried to charge it as recommended by the manufacturer. However, when I did so, the charger's light did not illuminate. I checked the charger, I checked the contacts, all seemed to be fine, but still it wouldn't cause the charger light to illuminate. I placed it in the charger for 5 hours and then checked the output voltage of the battery - only 0.8 volts. My original battery charges in just a couple of hours, no problem. Clearly this new one is a defective battery. Too bad they don't check these things at the factory.
Digital camera Review: Battery Life short Summary: 2 Stars
After charging this battery and using it I found that the battery that came with the camera lasted much longer. This could be a fluke but I am not too pleased with its performance.
Digital camera Review: Beware Cheap Off-Brand Batteries Summary: 1 Stars
I purchased (3) CTA Brand "NB-4L" batteries about a year ago for a Canon Powershot SD630 camera. The CTA batteries seemed as good as my original Canon-brand battery at first. After about 10 or so uses and recharging cycles of the CTA battery, it began to hold less and less of a charge. All three reacted the same way. Now after a year of occasional use (maybe one recharging cycle per month on average), they now only hold enough charge for about 10 pictures on a "full-charge" while my original Canon-brand battery is still performing well. I don't know if this is a problem of the CTA brand, or of replacement off-brands in general. Given the cheap prices, I assume they all may perform similarly. I notice that a lot of the 4-star and 5-star reviews posted are posted by people who have just received the batteries and tried them for the first time in prime condition. They are not people who've owned and used them through many recharging cycles.

Took this battery with me on a trip as a back up battery for my Canon powershot 1100IS camera. This battery lasted me good 200+ pictures.
Digital camera Review: CTA Digital DB-NB4L Replacement Battery Summary: 5 Stars
Bought this as a spare. It has more amper hours then the Canon battery. Used both at my daughters wedding and this one lasted longer. I would definately recommend it and you cannot beat the price.
