Product details Product Dimensions: Non-Sony ones seem to be hit and miss. I can use refresh if capacity has dropped a lot, and it will sometimes bring a battery back into useable life. The problem with generic batteries is that you don’t know what you will get. I use a fancy Powerex charger that not only charges, but will also run Analyze and Refresh cycles. I ordered two more from ebay, branded Fosmon. See and discover other items:

Amazon is also not an option for any batteries for us Canadians as the prices fot batteries and memory cards are just ridiculous on Amazon.

There’s a problem loading mobilr menu at the moment.

Battery Capacity Tests

The capacity stated mAh but was probably in the ballpark of 50mAh. Unfortunately I don’t have any idea what was its original capacity, and I will have to wait for a couple of years to get data on the new generic batteries. I did number them and keep a list as to which camera they are used with, just to keep track of their age.

Do you have any recommendations on best rate to charge and discharge these batteries. Even the good brands, like Duracell can be worse than cheap ones OTB.

And, is there a “refresh” equivalent for these batteries? I’ve heard many good things about the Wasabi batteries and actually wanted to order 1 recently from BH, but apparently this is now a special order, I would have to pay additional shipping charges, etc. Thanks for sharing your experiment. One was horrible, two others are having problems after 4 years, with decreasing capacity, and more rapidly decreasing than sony original. One thing I was able to test is the individual battery weight, and it turns out that all the Sony ones weight exactly 57g, while the aftermarket ones weight between 39g – 43g.


If you use the Sony charger it probably charges the batteries fully, so the life may be shorter but the charge greater.

Now I get to have fun. Basically, it can discharge a battery at a certain rate amps and down to a specific voltage and calculate the power capacity of the battery mAH.

As for the compatible batteries it seems that there is no rule as to the stated capacity and the actual one. Does your rig seem reasonable for ob application? Product details Product Dimensions: I put the results in the table below.

I bought the Duracell battery after Duraacell ran the tests on the other batteries as I wanted to see if a respectable battery brand’s product is preferable to the no brand Chinese batteries on ebay.

Duracell go mobile otb

Basically, I took off the part that holds the battery, unscrewed the cover, and soldered two wires ootb the battery contacts. I took apart my Fosmon batteries and they contain two 3.


Suitable for charger DTC I do have to note that they are used in 5 different cameras so none of them get monile heavy use as they would if I was using the same one consistently for their lifetime.

Sony batteries are really good and they do last long.
