For me, the original battery in the HX9V (as mentioned earlier) no residual minutes indicates what but this VHBW battery does. The remaining minutes display is a nice feature which is known from other Sony cameras innately, but the display is with this battery rather not very precise.
Example video recording in PS Quality:
When starting the video display 61 displays minutes (See photo of me).
After 25 minutes of recording, the display shows still 53 minutes remaining time.
After 30 minutes of recording, the display shows still 52 minutes remaining time.
After about 32 minutes recording will cause the camera turned off completely, but this is due to the camera, not the battery. In the video recording with the original battery is done after 32 minutes, the same.
After switching on the VHBW battery shows a full charge at 191 minutes.
I can only give a strong buy recommendation. Battery tips for small money.
