1 BAD BATTERY 3 TRIED, ATTENTION!

I am very disappointed by this WEISS battery because it does not take into AT ALL promises its equivalence with the original battery CANON !!! and despite a flattering look (once into the case, how important ...) it does not hold a charge, and I will have to return: SELF MEASURED to date March 10, 2012, since its purchase in November 2011) on an EOS 600D: 153 pictures the first time, the second 20 photos, 43 photos after the third refill, and 31 photos only this time !!!! By comparison, I utlise in a regular alternation original battery (Canon 1120 mAh only, compared to 1420 mAh Weiss) and I raised 333 pictures at the first charge, and then 401 photos, and then 450 pictures : comparison speaks for itself ... On the first 3 charges, I could do (no video also) 216 photos with WEISS battery, against 1,184 photos with CANON, 5 times less than the CANON reference! I REALLY SUGGEST SO GOING YOUR WAY AND BUY CANON BATTERIES (more expensive, but at least they are working properly!) I regret having bought 2 WEISS batteries (fortunately I bought also prudently 2 batteries CANON !) I'll try the second WEISS battery to see if it has the same defect .....
CHANGE the comment April 20, 2012: after trying the 2nd battery, I moderate my comment, because I could take 433 pictures with it (very good), which seems to show that the former was an "accident "Manufacturing ... Moreover, Amazon traded me quickly the faulty battery against another, new, I will try also: apparently these WEISS batteries are very good, if it does not fall on the wrong .. . (ERROR manufacturing?) to follow, I test this 3rd WEISS battery on my EOS 600D. See some of the photos taken (raptors, warblers and kingfishers) on the home page of my site [...] .I spend my grade from 1 to 3 3rd waiting to test the battery: 410 pictures 3rd WEISS battery (1st test in May), this seems normal, and therefore, assuming that the second ongoing trial is good too, I'll bump my overall rating 4 out of 5 stars, not 5 on 5 in memory bad battery received at first, but I think (except accident), you can go ...
