One solution Re: [Yaesu-FT-60] FT60 battery question

 

I agree with the post on low voltage. Replacement needed.? There are alternatives if you are a hobbyist and want to "play" with the hardware.? I have put MY solution on Thingiverse. My solution used off the shelf Li batteries in a custom made 3D printed case. Some relatively inexpensive circuit and battery holders are required.? This solution gives a ton of storage, costs just a bit less than the standard battery but the batteries can be replaced in a moment and recharged out of the radio while new rechargeables are inserted.??
The biggest deficit is that the thickness of the radio increases about .25"? ? I think my battery pack has 4 times the amp hours but it has been awhile since I did the calcs and could simply be forgetting. One other thing, when the batteries go bad, it is easy and pretty inexpensive to replace.

Having said that, there are OTHER people who have also come up with a path they prefer.? There is some pretty good thinking going on out there.? Take a look IF you want to "play".? If alternative creating is not what you are interested in, it is much easier to simply purchase a replacement battery.??

It's a loooong story but my FT60 has rarely been used for the past 8-10 years.? We are moving and I anticipate a good bit of operation with it after our move.

I have three Yaesu FNB-83 batteries purchased when I bought the FT60 as well as the CD-45 (or is it CD-47 ?) charger -- 7.2 vdc, 1400 mAh.
?
I leave the batteries on the charger until the pilot light glows green showing full charge. ?When the FT-60 is first turned on, the display shows supply voltage. Two of the batteries show 5.4 to 6.0 volts, while one shows 7.2 to 7.8.?
?
The 5,4 volt batteries will last for a couple of hours while listening only, no transmitting.? I guess I should replace the two showing only 5.4 volts when they come off the charger?
?

OK, here is a follow up with the link to MY solution. If you are a hobbyist, There are many more options and each has an advantage and disadvantage.? Enjoy the hunt!

Hi Marty,
?
Great idea. To this 70+ ham op, this looks like something I've read about called, "3-D Printing". Is this correct?
If so, how would I get something like this for myself, having no idea how to accomplish obtaining the finished product??
 

To double battery longevity, improve your antenna with a Smiley 270A or Diamond SRH-320a, and turn TX power down to 2W. If you are not making it at 2W with a better antenna FM voice line-of-sight, odds are you won't be making it at 4-5W.(*)
?
That doubles battery longevity.
?
Want to quadruple battery life? Also add the Yaesu FBA-25 AA Alkaline case, and populate it with quality NiMH cells from Powerwerx or Maha. They are 2500-2700mAH - TWICE the capacity of the stock 1400 battery pack.
?
Want to improve battery longevity even MORE? Use an earpiece of mini-boom mic setup. What eats up battery liofe with HTs? KEYING the mic, and LOUD audio. What is the first thing you will do with the VOLume control if you are wearing an earpiece? You will turn VOLume DOWN.

(*) - I worked an astronaut who was aboard the ISS at about 450 miles downrange with my FT-60R at 2W TX power and a measley tape measure antenna: ?
