AA lithium batteries

[Kevin Rock]

For all you folks with Spartan Sprint or field rigs.  5-A continuous
discharge would feed my ATS-3 very well ;)  I could put 6 of them is
series-parallel to work for quite a spell.

Lithium batteries deliver 15-A pulse and 5-A continuous discharge

Specifically designed for applications requiring high power, long life,
and extended storage capability such as military systems, automatic
external defibrillators, and other remote and portable devices, the TLM
1550 lithium AA-sized batteries are presented as the first such devices to
deliver pulses of up to 15 A with a 5-A max continuous load. Delivering
4.0 V with a total output of 2 Wh, the batteries provide the high power
levels required by the latest products in an easily integrated
industry-standard package size.

Features include a self-discharge rate of less than 3% per year at room
temperature, and an operating temperature range from –40° to 85°C. The
glass-to-metal sealed batteries use nontoxic solvents, are nonpressurized,
and can be shipped as nonhazardous material. (From $5 ea/large qty—
available now.)

They've got a number of cool batteries on that site .. see the 10V
nominal 56AH pack? looks might small, and at 2%/yr self-discharge it
would make a nice emergency battery ..

I am always looking at alternative ways to haul my k2/pelican around....
I have been using the internal battery, & tuner qrp 15 watts...

However, last trip on a boat, I encountered a guy with a 706 and the small
MFJ switcher PS.  He DID have AC available,,,, and with questionable band
conditions, and when we could operate (ship's facilities available)  the
choice was easy USE THE POWER.

This has me examining how to Pelicanize my portable setup.
Maybe I will go with the k2/100 kat100. I loose only the battery, which
these little Tadiran Batteries could supply at SMALL SPACE cost.(for qrp op
only).
I will have the added space requirement for the kat100+MFJ+battpak, less
the present small switcher PS for recharging. I think this pile will fit in
my current Pelican....I wonder about charging those Tadirans.
Am I missing something....

Hi Bill,

The battery is only good for 2 watt hours.  So six of them does 12 watt hours.
If you pull 10 amps at 12 volts for 1 hour, that is 120 watt hours, so the battery
will last for 1/10 of an hour.  That's 6 minutes of talk time.

A couple of things go wrong though - the voltage will drop to 3 x 3.25 volts = 9.75
at 5 A per cell, which is too low I think, but 4 in series will make 16.3 volts open
circuit, which is too high I think.
