Great battery life, but keep a watch handy
on February 23, 2013
I just bought this battery, and decided to do a side-by-side comparison between a 3 week old Canon battery, and this brand new battery.
First off, both batteries were tested on a Canon T3i, at 1920x1080 24fps, with a Sandisk Ultra 16GB class 10 and a Transcend 16GB class 10 as the SD cards of choice. Also, both batteries were tested with continuous recording, 'til each battery died.
The Canon battery lasted approximately 90 minutes, while the Photive battery lasted approximately 86 minutes. So, it holds up within just a few minutes against a brand name battery, which is amazing for the price.
However, there is a catch. The battery meter does NOT show the battery life. It will go from full to dead with absolutely no indication. Not even the halfway mark. As it states in the title, keep a watch/timer handy to keep track of your battery life.
Other than the guessing game you may play with its life, it's well worth the price tag given how long it lasts. And the fact that you can shoot 2 full 16GB cards worth of video without changing batteries is big plus.
I would recommend going with the STK battery, as it lasts about a minute longer, and costs $2 less. And neither of these batteries report to the battery meter.
