Up until recently one downside of getting the Baofeng UV-5RA HT was that the extra capacity batteries made for the other variants of the UV-5R did not fit it. At the start of last week I found a 3600 mAH battery to fit the UV-5RA. It’s from eBay seller radioshop8888 located in Hong Kong. This link should take you directly to the battery.
The cost was $21 shipped from HK to the US.
Here are some pictures, with a regular Bic lighter for scale. First, the UV-5RA with the stock 1800 mAH battery, then with the 3600 mAH battery, and finally the two batteries together.
Note that my radio is fitted with a Nagoya NA-701 2M/70cm antenna. It provides a little better performance than the stock rubber duck.
Aside from having double the capacity of the OEM battery, the extended battery makes the HT easier to hold, especially when you’re trying to work the buttons while holding it with only one hand.
