Digital Cameras Photo Reviews of CTA Digital DB-NB4L Replacement Battery for Canon Digital Cameras
Customer Review: CTA battery - you get what you pay for
Summary: 1 Stars
I bought two of these CTA DB-NB4L to supplement my original NB4L from Canon. This was not a replacement situation, but an upfront purchase along with the camera: I like to always have 3 batteries with me when traveling - one in the camera, one in the case pocket, and one back at the hotel or home recharging. I always rotate them from camera to recharger, recharger to pocket, pocket to camera. This system allows me to always have a guaranteed minimum of one full battery's worth of shooting on each foray out of the hotel/home, while at the same time never having to recharge a partially emptied battery (which is bad for battery life).
When these CTA batteries were new, one charge lasted about one third to one half as long as the Canon genuine NB4L that came with the camera. When you look at amount of charge per dollar spent, that was not a bad deal... a third of the charge for a fifth of the price!
But now it's been 2.5 years. The CTA's are now nearly dead. They can hold a few minutes of charge, just enough for an emergency situation, 10 pictures or less. The original Canon NB4L is still going strong, so I'm actually going to splurge and spend another $35 for one of those now. Over time, the genuine battery is a better deal.
Customer Review: Great value, ok battery
Summary: 2 Stars
I'd give this 2 1/2 stars if I could! For me, 2 1/2 stars means ok.
I bought this battery about a year ago. I never scientifically tested it, but it lasted as long as my canon battery at first.
I've noticed recently that it hardly holds a charge now.
I do use my camera a lot (Our fist baby was born about a year ago too!), but the official cannon battery has lasted just fine. I leave one battery in the charger and trade them when one goes dead, so I use them equally.
Now I'm not saying this is a horrible battery, and I still think it's worth it. I'm actually buying another one! Considering the fact that the official canon battery is 4 times the price, I still think it's a good value. I could be wrong, but I don't see how the cannon battery will end up lasting 4 years!
If you can deal with buying a new battery every year, this seems like a good deal for a secondary battery.
Customer 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.Customer Review: Completely Fails as a Replacement Battery
Summary: 1 Stars
I ordered two of these as back-ups for my Canon Powershot SD750 and they're complete crap. The instant I took them out of the package I was worried because they were so light in comparison to the original battery that came with the camera and unfortunately my worries were well-founded.
The life on these batteries is utterly feeble - I'd estimate it to be less than 50% of what a standard brand-name battery would be. Worst of all, they appear to lose their charge over time when unused - so I've had occasions where I've reached for them as the back-up only to find that they're virtually dead.
I tried everything I knew of to boost the performance from trying to 'reset' the memory of the battery by draining it completely, to leaving them in the charger for 36 hours and nothing has worked.
You get what you pay for with these - better to invest a few more dollars and get a battery that actually works.
Customer Review: Good for a while; then rotten for the rest of the time.
Summary: 2 Stars
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.
