Review: Great for camera - I have worried about leakage and damage from a battery in a 1996 Pentax model 6x7 that does not get used that often. I am in the habit of taking the battery out when I finish a roll of film, but then we get into the shelf life of the alkaline cell that I had been using. The Silver Oxide type not only promises greater shelf life, but it also can deliver more power at the correct voltage than the cheaper alkaline type. For the money and amount of use, this battery makes more sense.

## Questions & Answers

**Q: Is this a rechargeable battery?**
A: This is not a rechargeable battery. It is a silver oxide battery.

**Q: is only one Battery?**
A: Yes, its just one.  Silver cells are a bit more expensive than their alkaline equivalents. However, if you need a battery where a  stable voltage output is important, silver cells  are better than alkaline.  I use this battery in a film camera with an electronic shutter. The manual calls out the silver cell as the preferred battery to use (however the alkaline equivalent can be used as well).

**Q: Why does copy NOT match image?**
A: I DO NOT UNDERSTAND YOUR QUESTION.  THE BATTERY SHOWN IS FOR SIZE, THE BATTERY DESCRIBED IS WHAT YOU GET.

**Q: Can anyone tell me if this will work in a 1960's yeshica camera, 35mm film one thanks?**
A: If it used mercury batteries PX28, 4MR44 or others it should work. Google for modern equivalent of the battery it specified.

### ⭐⭐⭐⭐ Good battery when you need Silver Oxide
*by E***D on March 20, 2017*

When you need silver oxide this is the battery to get. I will not buy Alkaline in this battery size. Battery works just as expected. No complaints. Would buy again.
