I am a long time Sony user. I shoot with the a77ii and the a99ii now. I used to buy off-brand batteries since they were much less expensive. Over time, they do not hold up. I had Sony batteries last much longer, none have failed, even those over 7+ years. My off-brands have begun to fail after a couple of years. You get about 100 or so shots and they are dead. I have tossed them and now only use the Sony brand.
I don't own this particular camera, but I've shot thousands of hours with numerous Sony video cameras. I've tried a wide range of aftermarket batteries over the years, and they never hold up as long as Sony batteries. Both in terms of run time, and useful life. There's a reason they are so much cheaper.
