Review: Power One recommend leaving the battery in air for 5 min before ... - These are decent batteries and cheap if you buy in bulk. Power One recommend leaving the battery in air for 5 min before installing it to extend battery life. I'll give it a try. Don't quite have the zeal to carry out a controlled experiment
Review: Great delivery shame about the packaging - The batteries are very good and work great with my hearings aids. Some other brands of batteries cause various problem's including cut off, etc.. Usual problem. Packaging was so over zealous it would not fit through my letter box (which is large). Please desertcart, great delivery but save our planet and use less packaging.

## Questions & Answers

**Q: How are mercury free different from the others?**
A: Mercury free is pretty much all you will find these days.  They are different from older batteries in that they use oxygen from the air to produce power, which is why there is a sticker on them covering a small hole to keep them from discharging in storage.  You need to wait 1 to 2 minutes after removing the sticker before trying to use them, to give them time to charge up.

**Q: What is the voltage?**
A: 1.45

**Q: Is anyone using these batteries in a Starkey over-the-ear hearing aid?    I would like to confirm they will fit before placing an order.**
A: I use a 312 battery in my Starkey hearing aids that fit over my ears. The hearing aid manufacturer says to use this particular product. I have also sampled other 312 batteries that I purchased in the grocery store and they fit the hearing aid too. Any 312 should fit. I have found so far this brand to be the longest lasting battery I have used.

**Q: Are these batteries rechargeable ?**
A: No.  Although any battery can be recharged, this battery was not designed with the built-in safeguards for recharging.
