Hi guys. I just bought a canon 550D from l2P electronic fair and of course it came with quite a number of freebies. Among them there is this irrou japan li-ion battery. The spec stated at the battery was fits for LPE8 (battery for 550D)7.4V, 5800mAh. Another thing i noticed is that this irrou battery when inserted into the 550D charger, it is kinda loose. So i would like to ask if this type of battery is safe for use? Will it damage the charger or the camera if i use it? 5800mAh seems alot compared to the original battery for 550D (1120mAh).
