Replacement battery, perfectly compatible with Pocket Camcorder Sony TG7 including with infolithium system (which shows in real time the remaining charge time). More capacity than the original (over 100 ', against 75' for Sony) recharges without problem on the camcorder itself (this is not the case of all replacement batteries, Sony detecting certain as "Foreign" and "inconsistent"). Very good priori product, remains to assess its behavior in time and the total number of charges incurred before the collapse of capacity.
