Raimo,
I too have been known, on a rare occasion, to leave the master on. I think I've
done that three times in the last 5 years. First two times it was with an
Odyssey
680. First time it happened I put a charger on it and it came back like
new. About 18 months later I did it again. Put the charger on it and it came
back. But this time I was concerned so I replaced it with a new Odyssey and
put the old Odyssey in an old Jeep we use at the hunting lease. It worked in
that Jeep for about 4 years till my hunting bud left the key on for about 6
months. That pretty much killed it. Meanwhile, this spring, I replaced the
Odyssey
in the Europa with a tiny little, very light (and very expensive) LiFePo
battery. The Odyssey I took out went into the Jeep. The new LiFePo battery
seemed to work quite well for starting and running. Eventually, I did a
run-down
test to see how long it would operate the EFIS, EIS, Radio & Xponder. Turned
out, not very long. After about 10 minutes things started dropping off.
I recharged & balanced the LiFePo battery overnight and it was fine the next
day. BTW, I kept the charger/balancer on whenever the aircraft was in the
hanger.
Flew a couple times over the next week and parked it to do more testing.
This time I went off leaving the master on (with the charger attached, btw).
Next day, the battery was DEAD. And I mean DEAD. Would not accept a charge.
I put a new Odyssey back in the aircraft and plan to stick with them from now
on.

I have a little Odyssey story:
once I forgot my IBBS (Integrated Battery Backup System) on for several weeks,
which gives juice to my Gemini ADI (Tru Trak). It went empty and so went finally
my lovely Odyssey. Normally there is like fixed 12,58 V but now hardly 4 V
(four). I had a must to fly so I elected to fire upp engine w an external
battery.
I run the engine say 20 minutes and after that session it was fireable by
Odyssey only. I never noticed any failures in that brave battery but just in
case I ordered a new one (Odyssey retail shop is just 10 km from here). Now I
have a reserve battery, which is year modell 2006, has been in use 6 years, went
totally empty and still a new like. So far I will carry those extra kilos
happily
- want to hear more reports before updating more modern batt techs.
Cheers, Raimo
