PC680 batteries

[NinerBikes]

My buddy replaced his 680 in his RV-12 in Oct of 2018. It was dead by May 2019. Probably 34 hrs of flying time in that period. Dead cell. Air Spruce replaced it under warranty. New battery was dead by early Sept this year. Dead cell ,voltage falling of 0.1 to 0.2v per day. Lasted 4 months. Air Spruce replaced it again under warranty. Had to pay return shipping.

RV-12, and it charges normally, at 14.3V after start up, at about 8 amps and quickly falls, if on a Rotax 912, the rpms for warm up are kept at 24-2500 rpms. At 2000 rpm, the battery is -2 amps /hr.

I saw another post from someone also mentioning short battery life on their 680 recently.

I?m curious to know if anyone looks for parasite drain that would lead to long term undervolt on the battery. Is the amperage draw truly zero when the master is off?

My first Odyssey lasted 4 years, the second lasted 3, and today my third one went dead only after 10 month of usage. I fly my -7 regularly and never used any battery chargers. As mentioned by others, quality has been going downward in the past few years, even though some people seem to be happy with theirs.
I?m tempted to just go to Walmart and buy a cheap tractor battery, cannot be any worse, can it ?

It is if that's all you have connected to the + terminal.......

10 year old 7, 1500 hours - I fly a lot.
First one lasted three years and totally drained twice but came back to life both times.

Second one lasted four years and totally drained once but also came back to life.

Third lasted over two years.

Fourth installed December 2018 - dead in September 2019 - never drained.
Fifth one installed September 2019 - Dead at Petit Jean October 2019 (this month). Again, never drained.

Sorry, Larry, there is NO parasitic drag. None!
I have both PC680s sitting on a bench and am testing them with a NOCO g7200 and load tester. We'll see, but I suspect something is being built differently at the factory.


Just installed an Apex.

My buddy is once again replacing his PC625 Odyssey in his Cozy MKIV with less than a year of service on it. We talked about it yesterday and he is going to give the Apex battery a try for a replacement.

The Odyssey battery folks have a list of approved chargers here:

I use the BatteryMinder 128CEC1 with no issues on my 9A........yet, it's only been three years though (as second owner).

thanks but I want a new one considering how much of a pain it is to replace.
