I received a sample DSM-U84 battery just before the weekend for testing and review. This battery is a direct replacement for the Sony BP-U60 type battery typically used on the smaller Sony PMW cameras like the PMW-150, 200, EX1, EX3 and F3. It docks directly with the camera and does not need to use a cable or any other adapter to power the camera. This is particulary significant for PMW-100, 150 and 200 users as the cameras power socket is located inside the battery compartment making it impossible to use an external power source when a battery is inserted.

The capacity of the DSM-U84 is 84Wh so about 20% more capacity than the BP-U60 but in the same sized package. In my tests this did equate to around 20% more run time on my F3, about 3 to 3.5 hours which I think is pretty good. Like the original Sony battery it has an LED capacity meter on the rear of the pack and the quality of the plastics used appears very good. The battery uses high quality Japanese sourced Panasonic cells so should give a long service life. You can charge it using the standard Sony charger. With an estimated list price of £130 + VAT this makes it a serious alternative to the Sony BPU-60 which is typically around £170.00.

One point to note is that the DSM-U84 does not feature a D-Tap socket like some of the other 3rd party batteries on the market. According to DSM this is stipulated by the cell manufacturer for safety reasons. I’ve used many DSM batteries over the years and they have always lasted very well, I have some that are now at least 6 years old but still perfectly useable.
