Extend your photoshoot shoot for longer with two large capacity replacement batteries (1100mAh/83 14W) and a dual slot Charger I only own the A6000 and not other Alpha models. It is difficult to assess power drain on these cameras because much depends on its complex settings and operations. A more straightforward battery test per below instead loads its NP-FW50 batteries with a 20 ohm resistive load thus eliminating camera variables. At a nominal 7.4 volts, that results in a 370 milliampere load. Although the load is somewhat greater than camera operations, the resulting relative voltages over time reflect valid storage capacity and drain characteristics. RAVPower or Neewer are the best batteries. While they don’t meet their labeled capacity, they are close. What they do have is higher tested capacities than the labeled 1020mAh of a genuine Sony battery.

There has been considerable discussion on the Sony Alpha A6000 camera batteries since the camera was released in early 2014 because the relatively small battery does not have a large capacity. Much of the Internet and forum information has not had much value as users make vague assessments of what they seem to notice. I've been an electronic tech in Silicon Valley for decades. The capacity of my Sony battery was 1020 miliamp-hours at a nominal 7.4 volts. Other brands have often been rated higher while informal user assessments have tended to indicate the Sony battery has more capacity than off brands. I found that true for off brands in 2014 but since 2015 have been buying DSTE batteries that actually last a bit longer than the Sony battery. Although they are rated at about 180% of the Sony capacity, they don't have that much more relative capacity. If Sony approves the customer’s price match request the below terms apply. If Sony does not approve the customer’s price match request the customer will be informed of this. Terms that apply where price match is approved: My Sony A7 gets about 2 hours of life out of a battery. A 500mA load was used because it would drain the cells in approximately 2 hours.

Price / advertising errors (technical issues, misquotes, or listings which are suspected to be incorrect). Aside from the voltage curve, are there other factors that might affect the performance / operational stability of a camera when using third-party batteries? Or is camera performance / stability based entirely on the voltage curve? Besides the Sony battery, I bought 3 other brands. Only one of the batteries, number 7, was unable to power the camera for more than a few minutes thus bad. Battery 2 and 5 were functional though with poor capacity. Two batteries, number 5 and 6 initially seemed bad in that they held little capacity after seemingly being charged until I had performed a couple full discharge and charge cycles, after which they have been performing ok though with weak capacity. Thus it may be possible to recover a faulty battery by fully discharging it and then recharging. The spare batteries I bought in 2014, numbers 2 through 6 had lower capacity. Batteries bought in 2015, numbers 8 through 15 from DSTE have more capacity than the Sony. I bought 4 more from DSTE after starting the test, numbers 16 through 19 that show modestly greater capacity than identical types with a couple year's use. Thus at least with that brand, it does not show significant aging.

If you need a USB NP-FW50 charger, this one charges batteries. I am going to continue to use it. If you want an adapter that plugs into an outlet, get a DigiPower TC-U450. Sony Cameras That Use NP-FW50 Batteries Differences in price mean you can get 4 RAVPower or Neewer batteries for the price of 1 Sony battery. When the cell reaches 3V, it is considered fully drained. Discharging the cell past 3V can shorten the life of the cell. The cells are in series, so 6V was used as the cutoff for the batteries.Is it possible that the voltage monitor in the a6000 might "misread" the voltage of a third party battery, and thus drain the battery past the normal cutoff point (i.e., Battery Exhausted) that is monitored in the a6000? (I guess anything is "possible" so maybe I should ask if it is somewhat likely). Extra lightweight battery case easily store with your equipment moisture proof case for your peace of mind If you’re cheap like me, you don’t want to pay the high-price for an OEM Sony NP-FW50 battery. The price isn’t terrible if you only need 1 extra battery. Unfortunately, one of the problems with the Sony A7 is the short battery life. At the end of the week, all of the batteries read 0.02V lower. This is a negligible amount. You would not notice the difference in charge from a battery that sat for a week. All of the batteries started as showing a 100% charge in my Sony A7. Neewer & RAVPower USB Battery Charger
