Title: Beware Cheap Off-Brand Batteries
Review: 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.
Is the review positive or negative?
