Sony M series Replacement battery

S-8M91 is the replacement battery for SONY QM-91D, compatible with SONY HVR-A1E and DSR-PDX10. S-8M91 can exchange digital info with the cameras, and display remaining power info on the camera viewfinder. 

32Wh / 4.5Ah Capacity
With 7.2V nominal voltage, the S-8M91 has 32Wh / 4.5Ah capacity, and can run approx 5.5 hours on SONY HVR-A1 camcorder when LCD monitor is on.

Adopted high quality Lithium cells
Over more than 15 years, SWIT has been leading brand of broadcast camera batteries. The first reason is the high quality Lithium cells we adopted.

The high quality cells featured long life, durable, safety, and most of all, the cells has very little difference to each other, which ensures the high performance of the whole battery pack.

Moreover, the cells we’re using, have a smooth discharging curve by voltage, so that you can judge the remaining running time accordingly. Also when in storage, the self-discharging rates are very little, that extends the battery life effectively.

Multiple Safety Protection Design
The battery has an MCU to measure and record the real time data, and will cut off power when over-voltage, under-voltage,
over-current, high-temperature of low-temperature is detected.

Meanwhile, the battery housing adopts high-impact ABS material, with waist design and non-slip tread for secure handling.

Cell balance adjustment
After the batteries are used for a period of time, the cells voltage might get difference, and our specially designed circuit can
optimize the imbalanced cells, to prolong the battery life.

Key Features:

  • Li-ion battery pack of 7.2V nominal voltage
  • Comparable to SONY M series DV batteries
  • Display remaining power info on camera viewfinder
  • 32Wh / 4.5Ah capacity
