Odyssey battery approval?

[UP-M5]

just wondering if anyone here runs an odyssey dry cell battery in their maule. they are supposed to be a very good, powerful battery. but i guess they would require a field approval for installation.
has anyone done this?
any opinions on if it is even worth it?
it is supposed to be 10 lbs lighter- but maybe that isn't a good thing in the 540 powered planes

You can always replace the weight change with more survival gear.
I've heard alot of people discussing the Odysey battery so hope someone has real life experience to share.

I know, an old thread but I thought I'd throw it out there.
Log book entry if placed in the same location. Super cold weather performance and yes, 10# gone!

How can it be only a log book entry? Those things aren't TSO'd are they?

I got curious and did a web search. The following is from Odyssey's web site:
Odyssey® Aircraft Battery
FAA-PMA certified sealed aircraft battery for Piper models PA18 and PA19 aircraft. It can be used on other makes of aircraft, but will require local FAA field certification

I've had good luck with my battery, and it did require a field approval. I can't remember which PMI my mechanic was using, but he's here in Anchorage if you're up here now. Drop me a line if you want me to follow that up.
