Sony NPFW50 Battery

Product Information

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?

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. 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. 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. Energy stored in the battery is turned in to heat. The heat sink and fan are there to dissipate that heat. Testing Methodology

Specification

Comprehensive safety features built with a high-quality fire-resistant construction and surge protection The charger has multiple circuit protection to prevent over-charging short-circuiting and overheating Corporate offers where a valid account is necessary for eligibility or corporate (B2B) pricing or quotes. 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.

Precision Designed For Sony Batteries Made to the exact specification of SONY NP FW50 battery the charger is compatible with NEX 3/5/7 series SLT-A series and Alpha series such as: Sony NEX-3, NEX-3N, NEX-5, NEX-5C, NEX-5N, NEX-5R, NEX-5T, NEX-6, NEX-7, NEX-C3, NEX-F3, SLT-A33, SLT-A35 , SLT-A37, SLT-A55V, Cyber-shot DSC-RX10, DSC-RX10M3, DSC-RX10M2, DSC-RX10, Alpha 7, a7, a7rii, Alpha 7R, a7R, Alpha 7S, a7S, a7sii Alpha a3000, Alpha a5000, Alpha a6000, a6300, a6500, DSC-RX10, DSC-RX10M3, DSC-RX10M2, ILCE-QX1, ILCE-6300, ILCE-7SM2, ILCE-7RM2, ILCE 5000, ILCE 5100, ILCE-6000, ILCE-7, ILCE-7M2, ILCE-7R, ILCE-7S, Digital Camera and more.The TEC-06 is a USB powered battery capacity tester. A test load can be placed on a battery. The measured capacity is displayed on the screen when the battery is fully drained. a) the product you are asking Sony to price match must be identical to the one being sold by Sony, including matching brand, model number and colour (“Qualifying Product”); Batteries will slowly discharge over time. This is an issue with high drain rechargeable Ni-MH batteries. There was almost no change in charge of the FW-NP50 batteries over the course of a week. Self-discharge is not a problem you have to worry about.

Versatile charging option wall car and power bank charging available (All sold separately) or recharge inside the camera using the 2 1A Input Charger to maximize charging efficiency c) the Qualifying Product must not involve one or more Exclusions, see below at end of these Terms for Exclusions. Exclusions may be updated from time to time.A micro USB cable is required and not included. Charging requires 5V 2.1A USB power. USB chargers that powerful are not common. Most chargers will be 1A or less. Using a less powerful charger will still work, but charging will take longer than it would with a more powerful charger.

When battery voltage is lower than 1%, the A6000 displays a slash across its battery indicator. When it goes somewhat lower it will power off and upon powering on displays BATTERY EXHAUSTED. I found with the Sony battery, when the unloaded battery voltage was 7.39 volts or the 20 ohm loaded voltage was below 7.01 volts, it displayed a slash across the battery indicator. When the unloaded voltage reached 7.23 volts or 6.96 with a 20 ohm load, it displayed BATTERY EXHAUSTED. Thus the camera shuts down well before the battery itself disconnects its output and that is indicated on the charts at that 6.9 volt line. All values above 6.9 volts are shaded yellow indicating the operating range and that shows the batteries with highest capacities are active twice as long as the weakest. 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. I made the following report 6 months ago and am just now posting the information. Also have an Excel spreadsheet and additional images beyond the one graph below. 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.

Differences in price mean you can get 4 RAVPower or Neewer batteries for the price of 1 Sony battery.
