The bad ratings for this product appear to be directed toward the vendor moreso than the batteries in question. I've recently bought these batteries for use in a Canon dSLR. I really don't need an extra two batteries since I already have two Canon batteries but the price was so low I couldn't resist. My observation thus far is that they work just fine. While they may not last in the long run like the Canon batteries, that would need to be determined later.

These batteries ARE sold by and branded as Sterling Tek.

The price is great, the batteries take and hold a charge, the camera shoots pictures and doesn't flash errors or explode. That's what they're supposed to do.

I've used these with my 20D and they initially hold a charge longer than the Canons. I had a previous SterlingTek that had to be retired, but getting 2-3 years out of a battery at this price is a deal.

When it comes to batteries for CANON SLR system this is the way to go... They are one third of the price compared to the CANON battery and they work as good if not better. This is the way to go.

Being a frequent participant on photography forums, I've always heard great things about Stirlingtek batteries, and of the company itself. I'm happy to add my own recommendation.

First, even though I bought these through Amazon, which is a plus in itself, Stirlingtek immediately acknowledged my purchase, later followed by a notification that they had been shipped that same day! This is not typical of these third party purchases through Amazon. When I received the batteries a couple of days later, I was happy to see how well constructed they were. I immediately proceeded to charge them. The charging cycle and time it took to charge them indicated that the cells had some charge already, and both took approximately the same amount of time to charge. This is usually a good indicator that the cells are in good shape.

I have already begun to use them, with no problems thus far. I honestly can't tell how long they hold up, because I haven't yet had to recharge them! These are absolutely great batteries, with excellent capacity. And at less than half the price of one Canon battery for two Stirlingteks, you can't go wrong!

One more thing - Even though the description on Amazon says 1800mah, these are actually 2000mah! Even better.

I was hesitant to order an "off brand" battery from my Canon camera. But the price for two batteries was nearly half of what Canon wanted for one battery. My charger accepted the battery just fine. I was a little worried when I had to recharge the battery after 100 (or so) shots (also, its first use), but when I put the battery back in the camera after recharging it, it was still going strong after several hundred shots - I got back home from my trip before the battery gave out again. I haven't even had the opportunity to try the second battery that came with the order. So far I'm impressed.

Very pleased with purchase. Put battery through a grueling graduation event ; charge held up well.

Very satisfied !!

I ordered these batteries a lot later than I had originally planned on ordering them, and after the super quick shipping (less than 24 hours) I charged them up and took some shots. Wow. I loaded up my memory card and still had enough juice for another 75 pictures or so. Now I have two batteries that can outlast my cards, and my subjects. These were perfect replacements for my original BP-511 that came with my Digital Rebel, and I look forward to the next few years of shooting with them.

Accessory Genie does not carry SterlingTEK batteries the SterlingTEK ones work great. Amazon should kick AG off for false advertising.

este tipo de baterias, solo pueden ser calificadas por el tiempo que duran o que mantienen la carga, si despues de un ano o mas sigue funcionando como hasta ahora, seria mucho mas clara y veridica la informacion de los usuarios, ya que es la unica forma de calificar la calidad de las baterias, pero por el precio, vale la pena averiguarlo... hasta ahora muy bien, esperemos asi continuen, que tengan suerte, aunque no creo que duren como las originales.. pero habra que esperar.

I haven't had these batteries long enough to write a review. Amazon insists that I answer this, their 3rd request for an evaluation. So here you have it. Please stop bothering me.
