Title: Replacement battery
Post by: watebo on December 27, 2017, 08:25:51 PM
I have 2 genuine Sony batteries for my a330. They are both 6.8 volt, but one also says 870 mAh. The replacement battery is not genuine Sony and it is 7.4 volt and 1200 mAh. Will these differences cause any problems? Thanks.

I very much doubt it will cause any problems.  I have had mixed success with non Sony batteries and it can become a bit of a lottery.
One I have is indistinguishable from a genuine Sony and the other just decided that it was exhausted at an inconvenient time. It was fully charged according to the charger but dead in the camera.  Recharging did nothing and I had to toss it....john

The mAh is not a problem, it's the 7.4 volts that could possibly blow things like capacitors in circuit boards.

In my experience one problem is that genuine Sony batteries all have a micro chip in them that, among other things, tells the camera the percentage of charge remaining. The camera may or may not detect that it is using a counterfeit battery and could refuse to start.

What is certain is that if you use a battery grip it will not work if you use a counterfeit battery in #2 position. Other than that I have never had a problem with any counterfeit batteries that match the voltage of a genuine Sony battery. You may not get very good charging rates with them, as John says, "it can become a bit of a lottery".

To my knowledge all A mount Sony cameras use 7.2Volt, 1600mAh NP-FM500H batteries. I have never used an A330 so cannot be absolutely certain what it uses.

My camera came equipped with a 6.8 volt battery and I added another Sony battery. I don't know which one was the original. Thanks for your reply.
