why my $400 battery is = toast

- std lead/acid = batteries, even=20 agm ones, will sulfate if stored without being on a charger. Mine = sat for=20 a couple years. Most people know about this.

- charge life of a = std battery=20 is 90 days

- shelf life of a = std battery is=20 1.5 years

bringing back a sulfated = battery

- most = effective is a=20 pulse desulfator available here: www.geocities.com/powertugs

until 3/24. There's an = article there=20 that tells all about why it works.

- next best that I = can tell is=20 battery Minder + available here:=20

http://www.batterymart.com/p-batteryminder-24v-1-2-4a-battery-= charger.html

it has the high freq desulfator component. I'm not sure if it = does=20 pulsing.

- battery tender or power tender has a trickle = charge=20 cycle that will keep your battery from sulfating but I'm not clear it's = much=20 help if you've already committed the deed.

but why bother?

- Odyssey batteries are also lead acid batteries = but are=20 electrolyte starved version of AGM. This apparently = makes them=20 resist sulfation. They also advertise up to 500 deep cycle=20 life.

- charge life of an Odyssey is on order 2 = years

- lots of happy lancair drivers out there = with=20 Odyssey's. No complaints came back from my survey.

- caveat: Odyssey measures Ah life by a 10 hour=20 test. vs. I think Concorde uses a 1 hour test.

- Odyssey battery technical information is = available=20 here: http://www.odysseyfactory.com/ and=20 will lead you to the retail site.

- It looks like two pc625's will fit in the = standard IVP=20 battery box.

so far I can't come up with a reason for using an aircraft = battery. =20 It seems to be deficient in a number of = ways.
