Can you give the model number and where you bought it? The only Eagle
Picher I can find that is the same size as the usual 7 AH is also 7.2 AH.

Even @ 7 ah, we should support our own. The President of Eagle Picher

I used to offer Eagle Picher batteries.......the spec's looked impressive
but honestly I had more complaints with these than all other types I offered
and ended up replacing more and more often than others....finally elected
not to continue with this brand and offer now just Powersonic
batteries.......these are low cost and have proven to be excellent.

These 8Ah batteries have worked well for me.

They are 'High Rate' batteries, which appear to work
better under the ~1A that my panel draws. Even so,
each battery last about 5 hours.

Some are 10 hr, some are 20 hr rates. It makes a difference.
Easily enough
to
change the ads. Longer times (lower discharge rates)
make their advertising
look better.

The other technique is to change the discharged voltage,
or the charged
voltage.

If you want a better comparison, find the curves and
compare them. And the
weights.
And the size. You might be surprised to find that there
is little difference
in the
capacities. Chemistry is chemistry.

The other item is to pick a bingo voltage that is correct
for the
application, not the
battery. Compare the curves down to that point. If
the radio or other
electronics start
to go south at 11 volts, while loaded, the curve below
11 volts will not
take care of
everything that you want to do.

Hence twice the batteries so that the amp-hours are
way up there, cause you
can
only use a part of them.

Udo,

After 20 years on a 12-volt system, I've returned to 14 volts,
completely eliminating all problems with battery life. I'm using the PS
12/8 with a 2 volt piggy back. I am very happy with the results. Like
Ken, I purchase my batteries from ragebattery.

Several questions about this thread.

1. How does one piggyback (physical sense) a 2 volt
batter on top of the twelve in a well (i.e. Discus)
that clamps securely around the 12v battery?

2. How does one identify the dimensions of all the
various 12v. batteries offered by ragebatteries? (I
just looked at the site suggested two posts back on
this thread.)

3. Has anyone ever manufactured a 14v. battery that
would be usable?

The rage site has a physical data sheet for each battery ... or you
could go to the manufacturers site to see dimensions of the entire
line.

Nyal,

A picture would be best, but here's the narrative. I use hook locks (a
substantial step up from velcro) to mate the batteries. I place the
back (based on brand position) of the 2V against the terminal end of
the 12V about 1 inch above the bottom. This provides clearance at the
front of the battery tray and puts the 2V terminals slightly above the
12V terminals. I then use strapping tape to secure the attachment
between the hook and lock pads. I tested this arrangement by placing
both batteries in the tray of my Ventus 2 while trailering several
hundred miles. It has proven more than adequate. I inspect the bond
regularly and have found no weakening. Wiring is in series. Be sure to
include a fuse. If you have a strong interest, I'll be happy to forward
a photo. My wife uses the same set up in her LS-8. The 14V system has
dramatically improved the transmission quality and strength of her
Microair radio.

I am finding I can fly about 7 hours per 14V battery before I'm seeing
14.3V. I generally start the flight around 15.1V. I run an SN-10 with
one analog, Dittel FSG-2T, Cambridge Model 25 Data logger and read out,
a flap position LED, and gear warning.

With a 12V system, my SN-10 would start giving me voltage warning
around 4 hours and my radio would become discerably less reliable.

The PowerSonic model numbers are PS-1280 (12V) and PS-260 (2V). Rage
doesn't appear to carry the 1280 anymore. Try W&W.

I would appreciate the photo very much. There are
no gimmicks in my address. .

One further concern is whether 15.1v be too much for
my Volkslogger? I believe the L-Nav and the Dittel
radio would take it ok. I'll check that out, but I
believe the specs say that it will handle up to 20v.

Thanks!

On their way. Is the ellipses in your email address intended?
