So I have a pair of Canon BP-511 batteries, a pair of Digipowers (Best Buy Brand), and finally a pair of Sterlingtek's.
I decided to put these to the test today, to see just how many shots I could get out of each pair. My 40D takes about 108 shots in a row, at 6.5fps. Yes, the buffer is 75, but by the time you're at 75 shots, already part of the buffer has been cleared as the camera has written some images to the card.
The process is simple. I have 2 of like batteries in my grip, fully charged, and hold the shutter down until the buffer fills up. I await the buffer to clear, and fire away again. When a card fills up, I just swap, and my wife formats the card on our laptop so that no time is wasted. Here are the results.
Canon BP-511's (2 batteries)
Test 1: 3022 shots
Test 2: 3001 shots
Test 3: 3480 shots
Test 4: 3334 shots
Test 5: 2599 shots
Test 6: 3252 shots
Test 7: 3250 shots
Test 8: 3163 shots
Test 9: 2939 shots
Test 10: 2833 shots
Total after ten charges: 30,873 shots in 10 charges
Digipowers
Test 1: 2554 shots
Test 2: 2488 shots
Test 3: 2541 shots
Test 4: 2501 shots
Test 5: 2575 shots
Test 6: 2302 shots
Test 7: 2529 shots
Test 8: 2285 shots
Test 9: 2322 shots
Test 10: 2110 shots
Total after ten charges: 24,207 shots in 10 charges
Sterlingteks
Test 1: 3950 shots
Test 2: 3844 shots
Test 3: 4005 shots
Test 4: 2033 shots - something must've gone wrong here
Test 5: 3790 shots
Test 6: 4010 shots
Test 7: 4003 shots
Test 8: 4025 shots
Test 9: 3888 shots
Test 10: 3920 shots
Total after ten charges: 37,468 shots in 10 charges
My conclusion. The Sterlingteks certainly outperform the Canons, and most definitely the Digipowers. The Sterlingteks did show in test 4 some weirdness, as noted...which makes me wonder if their inexpensive price tag is showing through. Nonetheless, the Sterlingtek batteries provided 23% more shots per 10 charges than the Canons did.
Tomorrow I'll use a friend's Nikon D300 to perform the same tests. Has anyone else done similar tests on a Nikon?
