Hi Jonathan,
I messaged you privately, I think, because I don't want to clutter this discussion with a private issue.
Wondering if you got it.? If not, can you please suggest a different method for me to reach you. I have an FT-60 that needs repairs.
Thank you - Samer?

I had good luck with SUNDELY FNB-83 2000 mAh Li Ion battery pack
with wall-wart plug-in charger that I got several years ago from
eBay.

I bought this set of Li-Ion battery and charger, (FNB-V67Li 2200mAh Li-ion Battery with CD-47 Charger ?from Aimtobest). Guess what? its fit is not right."
I am really surprised at the aftermarket batts not fitting. They fit fine in both of mine and a friend's ft60. They are a tight fit, but not much different than the OEM ones. I squeeze them down (without much pressure) and snap the latch on it with my thumb. Can you post a pic of it or you can send them to my email?

Battery was properly charged by its charger to 8.2 volt. I left radio turned on when I was inserting battery to FT-60. ?my radio was lit on during the insertion phase. However, when I closed the latch, power was disconnected. I tried several times and it happened every time. Also battery does not slip into radio as smooth as OEM battery. I feel it is a bit longer. And my OEM battery has no such issue at all.
I guess I might need to buy OEM battery, not after-market ones.

Here is an interesting article on charging lithium?batteries.? The author is not a battery expert but he called on tow people?who are: "I called up two scientists who study lithium batteries, the University of Michigan’s Gregory A. Keoleian and the University of Maryland’s Michael G. Pecht."

500 would still be only HALF of the nmh cycles. It's a no-brainer.

I sure don't understand the infatuation with lithium ion. Lithium ion will give you about 300 to 350 complete discharge-charge cucles. nickel metal hydride about 1000 discharge charge cycles. Yes lithium ion is slightly lighter in weight than nickel metal hydride. So just stop ordering super sized fries and that'll make up the difference. Oh, and if you work or live in Alaska, lithium-ion does indeed perform better in cold weather. The only other advantage I can think about is lithium ion will hold a charge unused longer. But you know what? I don't charge up my radio and put it in the glove compartment for six months without use. Also lithium ion requires a appropriate charger. Straight voltage into it is not the best way to go.? -- Clint Bradford K6LCS Let's see how Siri did with this. http//

Hi, Ben & Bob,
Thanks. Good to know. It seems that Baofeng has a weak front end bandpass filter.
So in noisy environment, it is better not to use Baofeng. I am living in San Jose, CA, and has never encountered this front end overload.

I've seen the piddly (100mw, I believe) Part 15 transmitter in a Jabra Cruiser (a Bluetooth device that sends audio to the FM broadcast band) block a UV5R (well, technically, a GT-5R, Radioditty's version of a UV-5R with spurious emissions cleaned up, and transmit confined to the ham bands, but it's still essentially a UV-5R) in close proximity (e.g. in the same car, or the Baofeng attached to a mobile antenna). My FT-60 wasn't blocked at all in the same placement. Ben -- Ben Coleman nj8j@... "I love the way Microsoft follows standards. In much the same manner that fish follow migrating caribou."

Advantage of an F-T60 over a Baofeng??
Here's what my buddy found:? He lives near a hospital (which is on a hill) with several services broadcasting from that location, including several pagers, NOAA Weather broadcasts, etc.? ?Using the Baofeng from his home, he can hear all of the pagers AND the NOAA weather broadcast no matter what frequency he dials in to his Baofeng, so even hitting the local 2m repeaters is near impossible. He does not have any problem when he uses his FT-60.
My other buddy lives in a more rural area, and his Baofeng works just great, since there are no local sources of interference.?

I have read it. What I've offered has to do with, "What is the particular *meaning* with regard to particular battery types.?
For instance lead acid and lithium are utterly different in this regard.
That's not my opinion, it comes from battery engineers.

Hi, Halden,
Thanks.
I am doing a test now to see how good its battery is. I fully changed it on Friday and turned radio on at 8pm Friday. Radio is still on and working fine. According to spec, it should be able to stand idle for 72 hours. If it is above 60 hours, I am good with this set of battery.
If not, I can get another set of NiHM, or Li-ion (I hate to buy another charger), or as you said, replace the existing battery cells.
I programmed 600 local repeaters channels in the FT-60, But I normally use only 10 of them. I found my Baofeng is working as well as FT-60, but far cheaper ($150 vs $25) and much lighter. Baofeng's Li-Ion battery lasts quite long time. Can someone please tell me the advantage of FT-60 over Baofeng? When I go hiking, I grab Baofeng. I am all right if I lose Baofeng.

Hi John,
You don't have to replace your battery.? Just break open the battery case and replace the cells inside.? Some soldering required.? There are notes on this forum about how some people (including me) did it.? Plenty of opinions here about advantages and disadvantages of Li-ion vs. NiMH.? Either route will get you back on the air, reliably.? If you purchase a battery pack, measure its capacity while you still have the option to return it to the seller if the seller lied.
Cheers,
Halden VE7UTS

Where'd I get that number? That is what Yaesu cites in their manual for their latest HT - the FT-65.
