Dismal battery life

[wtp]

WARNING

at 3.7 volts each the radio should not last long !!!!

These look interesting for the 325P2...

Maybe one at a time.. 7.4v would let the magic smoke out of the radio..

Yes use only one battery the other slot gets a dummy battery

I would put a rectifying diode like a 1N400x in series to drop the 0.7V and to prevent the radio from charging the cell.

But more concerning is that the 18650 form factor is larger than a standard AA, so I don't think it will fit.

But the idea is sound: use an AA form factor Li-ion 3.7V cell in place of the dual NiMH AA's. Finding a Li ion AA cell that has more capacity is the challenge I've run into. It would be swell if someone made a dual AA form factor Li ion battery so we can take advantage of the entire battery compartment for the higher power density that Li-ion has to offer. At one point I found a rechargeable camera battery that substituted for two AA's but the capacity wasn't worth it.

That version of the battery offered by Amazon mentioned it fit in various types of electronic devices. Interesting idea with the diode. If we new the max battery voltage spec, that would be helpful.

Ordered a Eastshine S2 battery charger on amazon for $20 free 2 day delivery on Sat.

That's the one I had posted last week,
I have two, they work great.

Are you talking about the batteries or the battery charger?

14500 are AA size and would fit. But they are 3.7V, so unless you have some way to modify the circuits, they would fry the radio very quickly.

What's the current rating on the ones you have?

Using a 14500 would be sweet, and running it through a diode would drop it down to ~3V. But the 14500's I see on Amazon are only up to 2000 mAH, so no advantage over NiMH. I sense a business opportunity here

Yeah the printing is misleading up on Amazon

Beginning to wish I hadn't gotten rid of my 396t.
