Review on High-Capacity BAOFENG BL-5 Rechargeable Batteries - Compatible With UV-5R BF-8HP, UV-5RX3, RD-5R, UV-5RTP, UV-5R+ And UV-5X3 Radios - 3800MAh Extended Battery Pack (2 Pack) - Made In The USA by Robert Grind

I like that the products fit my UV-5R's, and the desktop chargers with no problems.I do not like that the charging port does not fit properly and must be fiddled with to charge. I also do not like that the actual capacity of the batteries is a little over half of the advertised 3800 mAh. The batteries were both cycled a few times and tested from a full charge. The first one tested has a capacity of 2112 mAh and the second one, 2144.I wish that manufacturers would just be honest about their products. I'd have likely bought them as replacements for my aging batteries that came with the radios even if they were advertised as 2100 or 2200 mAh because I prefer the longer battery since it makes the radio carry better when clipped on my pocket.As for the charging port, this type of DC connection has been around for a while and I can't believe it can't be fixed with just a tiny change in the socket design or assembly.It's frustrating.I hopes this helps someone make an informed decision.
