I Fixed My Sony P8 Battery

I used to take photos with Sony P8 before my last trip to U.S. The battery of the camera was complete dead. That is the reason I bought another one T10 in Tokyo airport.

However, I just few that T10 is not as good as P8, although it is smaller, with a bigger screen, and resolution is much higher.

Finally, I found out the reason.

P8’s aperture range is F2.8 – F5.6 while T10 is only 3.5. That makes a big difference.

For example, when the object is not briget enough, T10 is more likely to blur than P8.

How to Cure the Battery

I got a trick from my father. It is not professional, but it works. I wrapped the battery with newspaper and a plastic bag, and then put it into my refregirator. After two days, get it out and put it in the room for two days.

Now the battery is back! So far so good, and the charging capacity is almost like the new one.

Hm…. I know it is maybe dangerous, but at least it prove that it IS the battery problem.

I am happy that I can use my bigger Sony P8 again.

  1. I am going to wrap all my dead batteries in newspaper, put them in plastic bags and freeze them. If freezing doesn’t work, then I will use the oven.

  2. Don’t they sell replacement battery pack for the P8?

    Does this technique works for other types of rechargeable batteries? I will give it a try.

  3. very interesting. I will give the method a try. I have a couple bad batteries for our Moto Z3 phones.

  4. I ever got this method from a piece of electronic advert before, just like what you said above. And I had tried an battery of one of my old MOTO, which was with short power. But it did not work. I am not sure if it is my battery’s case.

    Anyway, it seems to be worth with a try.

  5. JS, Your tip of reviving the dead battery is interesting, and I would like give it a try on some of my cellphone batteries, which lose power very quickly. What I want to know is did you put the wrapped battery inside the freezer or the refrig? Will you send the answer also to my email box as I check my emails much more often. Thanks.


  6. er…did you put it in the freezer or the refrigerator? This sounds dangerous to me. Maybe this post should include the disclaimer “Professional at work. Do not try this at home” ;)

  7. Hi everyone, didn’t expect to receive so many comments. It did work, and I heard that you can try on all different rechargable battery. Not always work, but it is the same.

    You put it into the freezer – along with ice.

    Again, I do want to put the disclaimer here: It sounds dangerous – only only when you put it into the freezer, but also for the days to come – who knows what happens if the battery is handled like this. Will it be more likely to explode? No idea.

    So, do try it at your own risk.

  8. I tested this camera for a client. I didn’t have the light running for more than 15 minutes. The battery lasted approximately 6 hours before recharging. The LCD, however, had a few dead pixels – never saw this before. Tried returning for exchange and had to put up quite a fight. Anyone else seen this? http://www.batterylaptoppower.com
