EaglePicher has a 9A same sixe as a 7A, cost me about $20.

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.

Nobody has mentioned the obvious. Not everybody is using the same discharge
time.
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.

Chemistry determines the voltage, but the capacity is set by geometry and
design details. I know that Eagle-Picher has been working on inovative
woven mat designs to increase the capactiy of SLA batteries; perhaps the
unusually high capacity battery (for its size) cited earlier in this thread
uses this technology.

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.
