Can you charge NiMH batteries while they are on the radio like you would the original battery pack?

Everyone slow down, this Q/A section covers FOUR products . So for "BL-5" and "BL 5L" ("extended") your stock UV5R or BFHP charger you can charge those two types with battery on radio or off radio. Additionally you can also charge the "BL-5L" with a separate cable, including a special USB that has a voltage step up circuit. Now there are also another two other devices also listed here are a "battery eliminator" with cig plug adapter which has nothing to recharge so the issue is moot, and; the BL-5-AA, which uses AA batteries you put inside. You can put in regular alkaline AA like Duracell in there, or rechargeable AA (like rechargeable lithum, or if you are living back in the 20th century, NiMH or nicad) , but you can NOT charge your AA rechargeable lithium, nimh or nicad with Beofeng's chargers inside of that BL-5 Eliminator. - BL-5: Charges in standard uv5r Baofeng Charger "CH-5" while in radio or out of radio - BL-5L aka 3800 Extended: same as above and also with USB cable (there are several USB cables check you get the right one) - BL-5-AA: You can use non rechargeable AA or rechargeable AA, but you can NOT charge batteries while inside this BL-5-AA - BL-5-Eliminator: It has no battery, and obviously not an issue of charging. So guys and gals, with Amazon when you see these kind of listing for several products the QA, and for that matter the reviews, may be for any given one and not have correct info for the others.

Will this work with baofeng uv-5rtp?

Charlene,At first I was going to ask you if your sure it's a UV-5RTP but I looked it up on Amazon first and there is such a model. Yes, I strongly feel like the battery holder will fit. I always trial fit my battery holders and if they seem to be too tight I use a diamond coated fingernail file, course side, to smooth off the 'sharp' edges that go up into the radio. A careful trial and error fiting will pay off nicely in a smooth fit and the smooth click of the battery retainer. I have bought six of these battery holders and they fit the following radios I have, UV-5R+, BF-F8HP, UV-5X3. One other word of caution, you need to use some silicone caulking to insulate the center 'Bus Bar' at the top in the middle, not only does it insulate but it acts as an adhesive to keep the bus bar from working loose. Some on here have commented on how the bus bar can work it's way out of the groove and cause a short possibly starting a fire and or melting the case. I believe some have even posted pictures of the area that needs treating. I have done all of mine and sleep soundly. I think the pics are in the customer reviews of the battery holders.James

How does this operate? With a BF-F8HP will it transmit with 6 AA batteries? What is the dummy battery used for??

I bought this for the uv-5r witch mine is 7.4v to run, it says it on the back of the radio(not the battery packs) using 6 brand new 1.2v rechargable batteries won't even turn it on, since 6 batteries is 7.2v with rechargables, you have to use regular 1.5v batteries.
