Whether the voltage and capacity is correct, I can not judge defect testing equipment. That would actually be a job for the professionals and test magazines.
I like the technology of the battery can not scientifically assess / lens, the value for money but already:
44 Euro for 1200 mAh is a steep price.
For comparison: 8 x AA rechargeable batteries from Sanyo à 2500 mAh = 20,000 mAh cost RD. the half.
Ergo, this Fuji-part almost 40 x (forty!) Too expensive!
That's why I praise at this point, the Pentax K-30, which can be powered by 4 standard AA batteries / accumulators.
I know that this has only marginally to do with the evaluation of this part, you need therefore to write comments.
