BTECH, BaoFeng BL-5 Battery Eliminator for for BF-F8HP, UV-5X3, and UV-5R Radios

So far so good, charged this fully 8 days ago and it still has one battery bar left. It’s in use as a listening-only scanner most of the day (to my wife’s great dismay) only turned off consistently overnight. I also bought the little USB plug that charges this directly and it seems to work but I’ve only charged the battery once via dock as the beginning of the charge/discharge/repeat process. So far so good.

Bought this to upgrade my radio works amazing holds a charge greatly and doesn’t deplete very fast have left it on for over a week and still on 2 bars of battery left

As previous reviewers have stated, the top center battery terminal can easily come loose, touch another terminal and short out the pack. *I have not experienced this.* Although I have taken the precaution advised and glued the top center battery terminal in place so that it does not wiggle free. See photos. After this quick fix, it works safely and as expected. With 6x NiMH the battery life is considerably longer (2-3 times) than the 1100 mAhr Li-ion supplied with the Baofeng UV-5R. Another gripe about this product is how loose the snap mechanism is securing clam shell design together. I can pull the two apart pretty easily without hitting the release button. And also... please please please use the included dummy battery when using alkaline (1.5V) AA batteries!! If 6 alkalines are used, the radio will intentionally not work due to the higher total voltage being outside the operating range. Many people have given this product bad reviews because they didnt read.

I am impressed! This is a quality piece of work. The plastic is high grade and thick enough to be plenty durable. It has a very solid feel, and is a perfect fit to my radio. With the batteries installed, you cant tell it form the 3800MAH battery. Battery performance will vary depending on the batteries you use, but with 3800 MAH NiMH batteries, It lasted far longer than the 3800MAH LiON battery I bought with the radio ever did. BTW, that is why I bought this battery box. The Baofeng 3800 MAH LiON battery I bought was thoroughly depleted after just 6 months of use. I figured I could do better with NiMH batteries. I highly recommend getting this instead of the standard 3800 MAH battery. ATTENTION: Reviewer, For Realz pointed out a design flaw in this battery box that could cause injury. There is good chance the battery pack can short out if the middle battery contact comes in contact with the radio contact. There is only a small air gap between them. I used a piece of credit card plastic to insulate them, It wedged in tight enough it wont come out, but to be sure, you can SuperGlue it in place. This will solve this hazardous problem. This does not change my rating, but this *is* something you need to know.

In order for this 3800mah battery to properly fit the UV5RA a slight modification is necessary. Many videos say something about grinding inside the battery. Was not the case for me. A hot knife needed to cut the crescent shaped scallop off face of ext battery and it will now click perfectly into place on the UV5RA.

After reading a lot of reviews we decided to go with this one it seems this one doesnt get quite as hot as a lot of the other ones on the market but we dont know yet so hopefully this will work for us We did buy an adapter on Amazon that would plug into the wall which had a problem causing us to mistakenly not know if the battery illuminators were working correctly , We solved that were buying another adapter Works with baofeng 2015 model radio sold here on Amazon 1. Weve used it for several hours on standby and so far it has no heat whatsoever is cold to the touch We will try listening to a weather station and update you later ? 2. We have transmitted with it very little so far doesnt get hot at all Cold to the touch . If anything changes will update

The product arrived very well packaged, charged the battery and it has been powering my UV-5R just fine. In fact I ran the radio for about 6 hours and no issues at all, plenty of charge left. Will be buying another in the near future.

As others have reported, the battery pack would not snap into place on BTECH UV-5X3 (same as the UV-5R). I had to carefully file the plastic in a few places to make it fit on the radio. Also as others have reported, I found that the contacts inside the battery pack are poorly designed with very minimal spacing between the positive and negative contacts, resulting in the possibility of the contacts shorting together. Besides that problem, the metal battery contacts are made from very thin metal with very little spring to them, and are poorly supported by the plastic body of the case resulting in intermittent contact between the battery terminals and the contacts in the case. I also found that some makes of NIMH battery do not have long enough positive battery contacts to extend far enough into the plastic of the battery case to make contact with the metal contacts of the case, so only certain brands of battery make contact in the case. Ive spent about 4 hours trying to make this thing work reliably. Great idea - bad execution. I cant recommend buying this battery holder. With all the problems this thing has, I am surprised that BTECH sells it as it is.

First thing I did when I got this radio was run it down halfway through the battery, and then I fully charged it. It made it just around the 62 hour mark on standby without ever being turned off, with about 2 hours of solid listening from nearby repeaters and maybe 30-40 minutes listening to FM during the middle of those conversations. The math adds up about perfectly (I guessed around 60-65 hours of life based off 65mah/hour spec on standby), dont have to open it up to be sure youre being scammed. It is a genuine and genuinely good battery. Will be buying a second one soon as both backup and for my second radio if needed.

Battery fits perfectly and last days depending on what your doing but definitely a recommendation
