Extending HT Battery Life
According to the Cadex Corp ...
"The Eneloop NiMH by Panasonic and Sanyo has reduced the self-discharge by a factor of six. This means you can store the charged battery six times longer than a regular NiMH before a recharge becomes necessary. The drawback of the Eneloop to regular NiMH is a slightly lower specific energy."
The manufacturers of Eneloop also state their cells can be charged up to "2,000+" times - which is a little
contrary to existing literature on the NiMH chemistry. The Eneloop "Pro" only "500" charges.
Thanks for the update Mr. Clint.toggle quoted messageShow quoted text
What’s your take on Eneloop NiMH Batteries ?
Happy New Year
First inquiry of 2019 ...
>> ... Have you had any experience with any of the batteries that are shown on eBay at cheaper prices
for the FT-60R?
I tend to stick with local dealers or otherwise well-respected battery suppliers for aftermarket cells/packs.
There's a lot of rubbish out there ... with either no one to contact for support, or expensive or non-existent
The stock NiMH pack for the Yaesu FT-60R is the 1400mAH FNB-83. About US$36 at Yaesu dealers everywhere.
Properly charged, you should achieve about 1,000 discharge-charge cycles from quality NiMH packs.
Personally, I still use the empty Yaesu FBA-25 AA "shell" and populate it with 2700mAH Maha NiMH AA
cells. That instantly nearly "doubles" my run time (from stock 1400 to 2700mAH).
I further increase my run time by improving my antenna, and turning DOWN the TX power to 2W. I mean,
if you are not making it line-of-sight with a decent antenna at 2W on 2M and 440 - then you're probably not
going to make it at full TX 4-5W power. (Example: I worked the ISS FM voice when it was a few hundred
miles downrange at 2W and a handheld tape measure beam.)
I FURTHER increase my battery run time by using a headset or speaker-mic. What eats up batteries? Keying
the mic and transmitting, and turning up the VOLume of the received audio. What is the first thing you do when
you have a shoulder-mounted speaker-mic or are wearing a headset? You turn the VOLume DOWN.
SO ... Just using the stock 1400mAH battery packs - there's how to more than DOUBLE time between charges:
improve your antenna, turn TX power down, and use an audio accessory!
There are Li-Ion packs for the FT-60R. The advantages pf Li-Ion are that they will maintain their charge longer
than NiMH, and they perform better in freezing temperatures. And they weigh a little less than their NiMH
Personally, I do not charge up a radio and put it away for months - to be used later. And I do not live in
a frigid region. And the minimal weight difference? Nothing to get excited about.
BUT - quality Li-Ion packs will only provide about ONE-HALF the total number of discharge-charge cycles
as NiMH provides.
And so it goes ... Happy 2019!
