Negative Positive
Title: Good for a while; then rotten for the rest of the time.
Review: I bought the CTA Digital DB-NB4L Replacement Battery at the same time that I purchased my Canon PowerShot SD1000 with its original OEM NB-4L battery. For about one year, the CTA Digital DB-NB4L held a fair amount of charge and I could use it for about 1/2 the photo shots that I could with the Canon OEM NB-4L battery. After a year and a half of using both batteries on a constant basis, the Canon OEM battery allows me to take about 400 pictures before it needs a recharge. However, the CTA DB-NB4L Replacement Battery only allows me to take about 18 to 24 pictures before it needs a recharge. The CTA Digital DB-NB4L Replacement Battery is inexpensive, but you get what you pay for. I am going back to buying a Canon OEM NB-4L battery. I'll be using the CTA battery as a small paperweight.
Is the review positive or negative?
