Question: Will this work with the UV-5RA?
Document: Be advised that a particular seller (that claims to be the actual distributor for Baofeng) claims that their lower capacity 3600mAH generic battery will work with the UV-5RA radio - it DOES NOT.
This extended life battery not only doubles the talk time on a UV-5R, it also makes it a nicer size to hold in your hand. The only downside is that it is only compatible with the UV-5R, not the newer. UV-5RA. In order to make this fit a UV-5RA, you have to be willing to Dremmel one or both of the pack and the radio. If you do tough, it will work fine.
VERY GOOD TO HAVE WHEN YOUR LONG WINDED ON THE RADIO LIKE ME.LOLOL.IT ONLY FITS ON THE BAOFENG UV-5R. BUT NOT ON THE BAOFENG UV-5RA :-(THANK YOU.Capricorn1 BX N.Y.
Read the product description carefully! This battery is a straight drop in for the UV-5R ONLY! If you want to use it with a UV-5R+ or a 5RA+, you will need to be handy with an x-acto knife or dremel tool. The plastic patterns on top of the battery do not match those on the bottom of the radio and must be removed to allow the battery to snap into place.
I purchased the Etekcity 7.4V 3600mAH Li-ion Battery  along with the Retech RHA-771 Flexible dual band VHF/UHF HT Antenna(SMA-Female) to go with my New Baofeng UV 5RA Ham Two Way Radio 136-174/400-480 MHz Dual-Band Transceiver and they are a perfect match! The battery needed a small amount of simple modification with a Dremel to get it to fit the UV-5RA and now it is perfectly mated to it.
These work great and are factory Baofeng extended batteries. Just as pictured. Last a whole lot longer than the little factory battery.
There are two units one in the photos and the other one is the one you get. The one I received  has a curved front that does not match the straight front of the radio. It does work, after removing some material as others mentioned.
Very good price for the product. But the fit left alot to be desired. I bought two of  these batteries and neither one would fit up to the radio, and lock on. Maybe with alittle handy work with the right tool maybe a dremel and could have made them fit. But being brand new I was not going to do that and should not have had to.
I would absolutely recommend this as an addition for anyone who is going to be using their UV-5R radio on a consistent basis.
A nice accessory for my Baofeng UV-5R for those loooooong hikes, 4x4, or camping trips. And it fits in the drop-charger to boot.
Answer: I have order one and it fitted and has worked properly, I did not have to do any modifications
