In the last month or so it has become increasingly hard to find dealers or stores with 3rd party BP-U style batteries in stock.
After a lot of digging around and talking to dealers and battery manufacturers it became apparent that Sony were asking the manufacturers of BP-U style batteries to stop making and selling them or face legal action. The reason given being that the batteries impinge on Sony’s Intellectual Property rights.
Why Is This Happening Now?
It appears that the reason for this clamp down is because it was discovered that the design of some of these 3rd party batteries was such that the battery could be inserted into the camera in a way that instead of power flowing through the power pins to the camera, power was flowing through the data pins. This will burn out the circuit boards in the camera and the camera will no longer work.
Users of these damaged cameras, unaware that the problem was caused by the battery were sending them back to Sony for repair under warranty. I can imagine that many arguments would have then followed over who was to pay for these potentially very expensive repairs or camera replacements.
So it appears that to prevent further issues Sony is trying to stop potentially damaging batteries from being manufactured and sold.
This is good and bad. Of course no one wants to use a battery that could result in the need to replace a very expensive camera with a new one (and if you were not aware it was the battery you could also damage the replacement camera). But many of us, myself included, have been using 3rd party batteries so that we can have a D-Tap power connection on the battery to power other devices such as monitors.
Only Option – BP-U60T?
Sony don’t produce batteries with D-Tap outlets. They do make a battery with a hirose connector (BP-U60T), but that’s not what we really want and compared to the 3rd party batteries it’s very expensive and the capacity isn’t all that high.
So where do we go from here?
If you are going to continue to use 3rd party batteries, do be very careful about how you insert them and be warned that there is the potential for serious trouble. I don’t know how widespread the problem is.
We can hope perhaps that maybe Sony will either start to produce batteries with a D-Tap of their own. Or perhaps they can work with a range of chosen 3rd party battery manufacturers to find a way to produce safe batteries with D-Tap outputs under licence.
