Yaesu Original FBA-39 AA Battery Case (Fits 3 x AA Batteries *AA Batteries Not Included) for VX-8R Series - Includes: Belt Clip and Screws

Good back up for standard battery

Typical Yaesu quality. As another reviewer mentioned, it does appear to be at least water resistant, so you dont lost that feature of the radio just because you ran out of Lithium battery packs. Itd be a sad state of affairs to be transmitting at a whopping 0.8 watts (as is the case of the FT1XD when running on this battery pack) but for monitoring, short range simplex, or strong repeater work, itd most definitely do the job when your 2200mAh packs run out. I almost didnt get one for this radio (the FT1XD wasnt cheap, nor were the plethora of other accessories I had already added to it) but being the only radio without a AA pack, it was nagging at me. Better to have and not need...

The power output, when using AA cells is a little less than 1 watt, which isnt much, but is good enough for short range work. More importantly, it allows you to power the radio for listening, monitoring, scanning, recording with just a pile of AA batteries. Ive been using my FT3D as a scanner lately, and this lets me save my lithium ion batteries for two-way use, while powering the radio for scanning and recording with just my pile of AA NiMH batteries.

Perfect description, fast shipping. great experience.

Fits perfect and works as advertised. Will use as emergency batter in case Im unable to charge my battery pack. AA batteries should be easy to find.
