Question: Since the 'AA' rechargables are 1.2 vdc, that times 6 = 7.2 vdc, therefore; acceptable.
Document: Ever since I got my first baofeng one of the things I wanted was an emergency battery case. When I finally saw one that looked half-way decent I bought two. As a few others have pointed out, it takes 6 AA cells, which gives it 9v of output, unfortunately, the UV5R doesn't work well at this voltage. But if you fill it up with rechargable (NiMH) 1.2V batteries you get a nominal pack voltage of 7.2V which is what the baofeng normally works with.
If you are considering using this case, keep in mind it is intended to use with RECHARGEABLE batteries (1.2 volts per cell)... NOT Alkaline Batteries (1.5volts per cell). With Alkaline Batteries, the pack will have too high a voltage (9 volts) and the radio will NOT transmit. With NiMH or NiCd, the pack will be 7.2 volts, which is practically the same as the OEM battery (7.4v).
The solution is a &#34;dummy cell&#34;. I used one of my &#34;Bluecell 8 PCS Clear Color AAA to AA Battery Holder Converter Adaptor&#34;, purchased here on Amazon, with a stretched ballpoint pen spring inside to bridge the contacts. This works great, giving you 7.5 volts.If you're using rechargable AA cells, you get 7.2 volts with all six cells installed.
You can fix this one of two ways. Use your old half dead AA batteries or install one dummy AA battery, so that you are only installing 5 batteries into the case instead of 6.
Then I put the battery case back together and worked it in and out of the phone about 10 times just to make sure it functioned ok. It was easiest to get in if I pushed the case up as far as it would easily go, then put my thumbs on the bottom of the phone and my middle fingers on top of the phone and pushed them together.
I did this about 10 times to wear in the area where it slid up into the phone. Then I took the part with the latch and slid it up where it would latch. This was tricky because it had to line up just right without the other part to guide it in. The latch was very stiff and I had to really work it back out the first couple of times, but I did it about 10 times until it was working ok.
Instead of trying to force things, I finesse them. First I put a nice soft towel down on a table so I wouldn't scratch up my radio. Then I took the empty battery case and started opening it, taking it apart, and putting it back together. After about 10 times of doing that it opened and closed easily because I had worn the latches in.
The case was very difficult to open the first time but gets easier the more times you do it. I had to bend the connections inside in order for the batteries to fit snugly as they were to loose as the unit was shipped. Once I did that, it worked perfectly and, IMO, makes the radio a bit more &#34;hand friendly&#34;, as I always found the small size of the radio uncomfortable.
Unfortunately that wasn't the case. When first taking it out of the box, it has a good look to it. Unfortunately, there are critical flaws in the construction that just ruin the product.First is the flimsy clip at the bottom that holds the two halves of the together. It simply doesn't work well. I installed 6 NiMH batteries, closed the case and it pops back open.
Needs a bit of filing on the latch up top; otherwise you'll have a real bad time ever removing it. Once you can get the pack in and out OK, the fun begins.The radio will receive just fine if it gets more than the 7.4 volts the Baofeng batteries put out, but it won't transmit. If you fill this pack full of alkalines, you're going to get a bit more than 9 volts coming out of the pack.
Answer: Yes.  In fact, do not load the battery case with 1.5V batteries.  With that voltage, the radio will not transmit.
