379 Watch Battery Voltage

Worked perfectly in my MacPro 5.1   I had to remove some other ram I had in my machine as it was not compatible. (watch out for the voltage of the Ram and if it registered)

Awesome little light. Especially for free,after spending $379 anyway

Great product. Price varies from 379 to 430. Track and buy

So I'll just get this out of the way... the battery life IS as bad as everyone says. HOWEVER, if you switch the meter to voltage, you'll see how much power you actually have left. Aftermarket batteries don't give accurate readings. So, first upgrade, after a cage and T5 should definitely be a V mount. Aside from that WOAH BABY! The performance is exactly what I was hoping for! Shot on a GH5 before. And now I look at that camera like it's going to collect dust or just be the in case backup. No stabilization, no problem though if you have a solid gimbal setup. The image is INSANE!

In a rechargeable battery the important things are 1. Ability to hold charge 2. Provide the expected voltage at terminals when charged 3. Capacity to hold enough charge (mAhour capacity) 4. Ability to be charged repeatedly When I got the batteries they were not charged but this was stated so I charged the batteries. All 16 charged up and provided expected voltage (actually a little bit higher, about 1.44 Volts). I don’t have a battery tester so I am unable to say if they charged up to expected mAhour capacity. However, since they seem to be performing OK , I will assume they charged appropriately. I am unable to say anything about how many times they can be charged since that is a long term test. So far they have performed. Five stars. Ajeet S.

Wein's battery is an exact replacement for the old PX625 mercury cell in that it provides the proper voltage for the inboard metereting systems on my trusty old Leicaflex SL's to once again work properly. Greatest thing since sliced bread,

I purchased this adapter to provide an unlimited power source for my Canon R5 using an Anker PowerCore Elite III battery and charger. Prior to using the adapter in my camera, I first plugged the battery in separately and verified that the output voltage was correct. I found the unloaded output voltage delivered to the camera is 8.47 volts which is slightly higher than the Canon battery voltage of 8.05 volts. When placed into the Camera, I found that my R5 functioned properly with no apparent loss of functionality. I'm now performing a long-term test external to the camera before putting it into normal service.

Whereas the voltage output of alkaline batteries has been shown to decrease over use and time, silver oxide batteries have a much more constant voltage output over the life of the battery. For this reason I prefer to use silver oxide batteries whenever possible. I chose the Exell S28PX battery to use in my Pentax digital spotmeter, which I've used periodically from time to time over the past two years, including in cold winter weather, and I've been very satisfied with its performance.

I use a (film) Leitz-Minolta CL. This camera originally used the 625 mercury battery. The 625 has been discontinued due the mercury content. The A625PX will fit the camera, but the voltage is slightly higher. My CL battery circuit was adjusted to accept the higher voltage of the A625PX. The new battery keeps my CL working. B&H is the only place I can find these new batteries.

I think this Battery is even better than the original version from Canon because the voltage is higher and it can hold more of a charge than the original Canon Battery ! It's a great buy at a great price ! Truly !
