Questions about this item

How long will the 4200mAh capacity last during continuous recording?

The 7.4V 4200mAh lithium-ion cell stores 31.08Wh, so run time scales directly with the camera's power draw; a camcorder averaging 10W will record for about three hours before the pack needs recharging.

Does the battery get hot or make noise during all-day shoots?

The DS-CS-QM91 has no fan or moving parts and uses standard Li-ion chemistry, so it runs silently; warmth is normal under load but stays within the cell's rated operating range.

Which Sony models or original part numbers does this pack replace?

It replaces NP-FM90, NP-FM91, NP-QM90 and NP-QM91 and fits camcorders such as the DCR-TRV10, DCR-TRV20, DCR-TRV30, DCR-PC100, DCR-PC110, DSR-PDX10 and HVR-A1J.
