Overpriced, However. - These dummy batteries fit perfectly and do their function just as perfectly. My wife picked one up after I unpacked the set from the box and asked why it was so lightweight. I told her it is just an empty shell with a wire going from one end to the other. Anticipating her next question I explained it is to cut the voltage in half with pairs of rechargeable lithium batteries. A new alkaline battery is typically about 1.6 Volts and a non-rechargeable lithium battery is about 1.85 volts. Most all electronics will handle non-rechargeable 1.85 volt batteries. The rechargeable lithium batteries are 3.7 volts, exactly twice as much voltage as a non-rechargeable lithium battery. It makes me wonder why they can't create a rechargeable lithium battery that is 1.85 volts, just like the non-rechargeable versions. But there is probably a good technical reason why it's not available on the market. In the meantime, the 3.7-volt rechargeable lithium batteries are abundantly available along with universal chargers. There's somewhat of a startup investment to take advantage of this method of switching from pairs of standard non-rechargeable batteries to rechargeable batteries. These dummy batteries are vastly overpriced, but they are not in full production quantities yet - still waiting for the demand to catch up. The same scheme is available for AAA batteries as well. I bought some AAA rechargeable lithium batteries with a regulating circuit in the end that made it 2 mm longer than a standard AAA battery thinking the spring would allow the extra length. I was wrong - too long. Now I need to buy some AAA batteries that are standard length. They won't have the safety circuit, but they will fit. The AAA version of this dummy battery was exactly correct of course - just the battery was the problem. I won't buy any more batteries that are 2 mm too long. They are useless if they won't fit - cost quite a lot extra, too. I'll probably find a place I can use the extra long batteries eventually, but so far, I haven't found anything where they will fit. You have to have pairs of batteries: One dummy battery and one 3.7 volt rechargeable lithium battery. If you have four batteries, you need two dummy batteries - doesn't matter what order you put them. Review: Perfect to use rechargeables... here is some info - Perfect "batteries" to take the place of same sized actual batteries to enable you to use Li-Ion and Li-FePo4 replacements. Many remotes and other devices run on about 3 volts and are set up to use 2 non-rechargeable batteries of 1.5 volts apiece in series to supply the 3 volts. Li-Ion and Li-FePo4 batteries are slightly more than 3 volts for a SINGLE battery. Thus, one Li-Ion or Li-FePo4 battery will easily power a device that is set up to use 2 non-rechargeable batteries. But what do you do about the other slot where a battery is supposed to go in your device??? You could run a jumper wire across and solder it... but that requires some real time and effort. Putting a dummy battery works just fine. If you understand the difference between batteries in "series" and "parallel" this should all make sense to you. If not, you might read up on it. But if your device uses 2 or 4 batteries and they are either put in end to end, or are alongside each other facing opposite directions, then they are probably wired in series and you can use a half and half mix of these and rechargeable Li-Ion or Li-FePo4 batteries to run it. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B010NDAITG | | Battery Cell Composition | Lithium | | Battery Cell Type | Lithium | | Best Sellers Rank | #1,333,730 in Health & Household ( See Top 100 in Health & Household ) #5,063 in AA Batteries | | Brand | BVYY | | Customer Reviews | 4.6 out of 5 stars 304 Reviews | | Item Weight | 0.01 Pounds | | Manufacturer | theeasyhomelife | | Model Name | lifepo4 | | Model Number | 4330206883 | | Reusability | Single Use | | UPC | 703194314754 | | Unit Count | 4.0 Count | | Voltage | 3.2 Volts | ## Product Details - **Brand:** BVYY - **Battery Cell Composition:** Lithium - **Unit Count:** 4.0 Count - **Voltage:** 3.2 Volts - **Reusability:** Single Use ## Images ![theeasyhomelife AA Size Hot Dummy Fake Battery Setup Shell, (4-Pack) - Image 1](https://m.media-amazon.com/images/I/61jfKrr7ELL.jpg) ![theeasyhomelife AA Size Hot Dummy Fake Battery Setup Shell, (4-Pack) - Image 2](https://m.media-amazon.com/images/I/31uAngTRU2L.jpg) ![theeasyhomelife AA Size Hot Dummy Fake Battery Setup Shell, (4-Pack) - Image 3](https://m.media-amazon.com/images/I/31m4TMonXkL.jpg) ## Questions & Answers **Q: I want to use these in a battery operated light string that needs 3 nimh batteries. can i use 2 of these with an ac converter in the other slot?** A: This product acts like a piece of wire, so if your converter is ~4.5 vdc, this should work as the equivalent of 3 AA batteries (1.5v each). **Q: Are these four batteries separate or are two glued together permanently?** A: hello,my friend, this fake battery is separate 1 pcs, **Q: Do u charge them** A: No they are just a place holder, the AA battery back pack for the hand held Bao Feng radio stated to put in one dummy battery so as to not over volt or amp the radio, that is the purpose of this item. **Q: How much do these weigh compared to real batteries?** A: Oh yes. they are much lighter. They must be hollow inside. I use them with a 3,7-volt lithium. In a three battery application, you can usually use two dummy cells with just one 3.7-volt. Of course, three 1.2-volt will last longer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fit Perfectly and Do Their Job Perfectly, Too.
