FT-60R Battery Case Question
|
Tom Seabury
开云体育Dan and Group,I talked to a Yaesu person a few days ago about this subject.? He added the same caution as the notes that come with the radio but also (off the record) told me that this is mainly for problems which might occur that Yasue does not want to get involved with. Things like law suits - I suppose! Most well designed battery's have a thermal cut-out device in series with the cells and will disconnect the cells if the current is excessive or the temperature of the cells is too great. Anyway, I carefully looked at the supplied battery and, if you look at it carefully, you will notice that the "end" AA cell - toward the bottom of the case, has the insulation removed from the bottom end of the cell.? This makes a contact with the radio to charge the cells.? If you want your rechargeable cells to charge with the supplied wall-wart, then just remove the insulation from the bottom of the cell that is in the bottom of the battery case. Presto the wall wart will now charge the cells you have placed in the battery case. BE ADVISED!!!! DO NOT DO THIS WITH ALKALINE CELLS AS THEY WILL EXPAND, AND EVEN CATCH FIRE.? ALSO I'M NOT SURE AS TO THE CHARGE RATE BUT I WILL ASSUME THAT YOU CAN CHARGE THESE NEW "CHEAPIE" NiMH 2000+ mAH CELLS THAT ARE ALL OVER THE PLACE, SINCE THE SUPPLIED CELLS ARE RATED LOWER - AT 1400 mAH. Hope this helps, Tom - KI6O __________________________________________________________________________ FT-60@... 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? Dan? - N7ZXL |
开云体育Just a side note, if you want the flexibility of using external power with the rechargeable pack that comes with the unit, not for recharging, but for saving the batteries, just place a piece of take over the insulation that was removed from the bottom most battery.? Then you can run your RT-60r from the accessory plug in your car and save the batteries, to continue the QSO while waiting on line at Dunkin Dougnuts!? Just remove the tape when you plug in the overnight charger. ? So many solutions, so little time. 73 de KE2QR ? Fred Jacobowitz _._.? _ _ ._???? _..? .??? _._? .? .._ _ _?? _ _._?? ._. KE2QR
