Check Sony's site for the model used on the TRV325, see if
it is an "F" series - if so, yours will fit.

Depends on if the reading is made with the panel VF open or
closed, or if the camcorder has been used a bit or just
turned on. Max. times can also vary depending on discharge
state when recharged. In any case, the numbers are at best
only a rough guide, having not a lot to do with reality...

If not "infolithium", the camera will reject them, alas...
(though some other brands made for Sony cameras may work
fine).
