Rechargeable NiMH AA's
When I purchased my FT-60, I also went for the FBA-25A AA battery
case. I threw in some older Energizer AA Alkalines to try it out and that works fine. However, I was mildly surprised to read in the manual that users were cautioned not to use rechargeable batteries in this pack because it did not include the usual current and voltage limiting circuitry found in their own rechargeable packs. Now, I can understand the point of this admonition if all they mean is not to recharge such batteries in the radio using the supplied power supply. However, I can't see the risk in using batteries recharged outside the radio on a free standing recharger. Am I missing something about NiMH batteries here? Is there some risk in putting six previously Energizer NiMH 2100 mAh cells in the unit? I can't imagine why there should be, but Yaesu's directions seem pretty specific here. If the more technically savvy amongst us can enlighten me, I'd appreciate the help. While we are at it, is there a drop in charger for the supplied FNB-83 battery. I'm told that the CD-29B rapid battery charger is not yet available. Is there an aftermarket drop-in charger that allows the FNB-83 to be charged (relatively quickly) outside the radio unit itself? I seen it suggested in an e-ham review or two that the VX-150 accessories will work. Is that correct as respects charging the FNB-83?

-----Original Message-----[FJ>] You can put any type of batteries in there! I use RayoVac IC3 2000maH batteries. The great thing about the FBA-25 is that when you apply external power, the power connection between the batteries in the FBA-25 and the radio is broken and the external power, powers the radio. Therefore, no matter what type of batteries you put in the FBA-25, you are not charging them by hooking up to an external power source! Of course, I take out my IC3 batteries and charge them in the RayOVac supplied charger, which must have some magic because they charge in 15 minutes! The overnight battery charger is not intended to power the unit with the FBA-25 installed. One caveate - just make certain, that the bottom most battery is not exposed to the 'charge-point' located on the back (internal) of the radio. It is very obvious if you look at the FNB-83 battery. [FJ>] This I leave to Brad who posted some news today about the availability of the drop-in charger and its proported ability to charge 3 technology types. 73 Fred KE2QR Dan - N7ZXL |

Perhaps you are referring to a posting or article elsewhere. If so, can you provide a reference or link. I am most interested ... and assume the "3 technologies" to which you refer are: NiCD, NiMH and Li-ON. In talking this afternoon with HRO (ordering a Diamond SRH-77CA) they advise that it is imminent but not yet there. Seems a bit pricey at $79.95, but ... I see no other choices on the horizon. It was also their impression that it was a battery-only (as opposed to whole radio) "drop in" unit. That would work for me. Less bulky and thus more easily packed for trips? The FBA-25A could easily serve to power the unit while the FNB-83 was getting charged.
