Avoid this battery - get the real "Sterling Tek" [Posted on 2007-02-05]
I had read a lot about the sterlingtek batteries in photography forums etc and then found this battery at amazon. The description of the battery says that it is from sterlingtek and so I ordered it. When it arrived I promptly charged it fully and inserted it into my canon EOS 20d. Everything went fine for the first 10 shots or so after which my camera suddenly stopped functioning completely! I tried switching it on and off - but it did not work. I then removed the battery and inserted it again and it started working again. I thought that this could be an isolated incident and so did not do anything about it at that point. That evening I took the camera out to take some photos and while I was shooting - the camera went dead again. This time however the camera did not start even after removing the battery and inserting it again. I did not have my old canon battery with me that evening and so I could not take any pictures all evening and I was really disappointed. I at once decided that it would be going back - as a battery that fails unpredictably while shooting was totally unacceptable to me.
I have rated this as 2 stars instead of 1 star as the return process was really good. They refunded the full amount including the shipping within 3 days of sending it back!!
The same day I ordered the real Sterling Tek batteries directly from their website (not from amazon). The batteries I got from Sterling Tek worked without issues. They also looked different from the one I got from amazon (which btw are shipped by eforcity) and so I realized that these batteries are definitely not from Sterling Tek even though the description says so.
Very good and reasonably priced BP511 replacement [Posted on 2007-02-20]
I bought two Sterling Tek BP511 replacement batteries from Sterling Tek directly. Didn't order from Amazon after reading JimJ review to avoid the problem he had.
The sterling Tek batteries came via US Postal Service. At $9.99 each plus $6.99 shipping for the order, the price came to $13.50 each which is very good.
The batteries are labelled as 2000mAh. If it is the case, then this is probably going to last a lot longer than the stock Canon BP511.
So far these batteries work fine. I took hundreds of pictures with one of them to try out the capacity (BP511 usually give me some 400 shots), but even using image stablization on a 28-135mm lens, the battery gauge still shows full capacity after more than 300 shots.
Have not had them long enough to report on long-term results hence 4 stars, but at this price, they look like winners to me.
Sterling Tek ordering, shipping and customer services are very good.
Not what it says it is ... [Posted on 2007-05-29]
The advertised 1800 mAh at such a low price (from eforcity) intrigued me, but upon arrival it turns out that this must have been a classic bait-n-switch deal since the battery is a generic type with little or no information on capacity or manufacturer. In fact, it doesn't even list a number for capacity. Just like a previous reviewer, I am using this battery in an EOS 20D and while I didn't have the same failures, the true capacity seems to be way below 1800 mAh. Compared to my original Canon battery with 1300 mAh (2 years old), the new battery doesn't last much beyond half the time it would with lower rated original. Stay away from this one!
Price, Performance Perfection [Posted on 2008-02-11]
I purchased two 2000 Amp hr batteries from Sterlingtek to compliment my new Canon 40D with BG-E2 battery grip - and to mix and match with my existing Canon 1390 Amp hr batteries purchased with my 300D (Digital Rebel) also with a BG-E1 battery grip.
In cold conditions at Lake Tahoe in November 2007 and 15 days in Maui in December/January with heat and humidity - the Sterlingtek batteries performed flawlessly. My Canon 40D equipped with a 28-135mm IS lens is a power hog - as is the battery draw from the camera's 3" LCD screen. I took over 700 shots on one full day shooting surfing, indoors using the 40Ds own speedlight and at night with a 580EXII shooting stage entertainment. The battery indicator indicated a 66% charge remaining!
I have mixed these batteries with the Canon 1390 Amp hr and also used them in tandem in both the BG-E1 and BG-E2 without a single problem. Using both the Canon and the Sterlingtek battery charger - I have had unlimited interruption free power from these batteries since my September 2007 purchase.
I'm currently rotating 3 Canon batteries and two Sterlingteks on my Digital Rebel and Canon 40Ds battery grips. Worried about battery OEM failures??? - for this price carry a couple of extras in the camera bag as backup so you can sleep at night.
As a serious semi-pro - I will always keep a handful of these 2000 Amp hr batteries charged and ready to go. Can't beat the capacity and reliability for the price.
