I learned the hard way with my Odessy battery that just "any old charger will do" is not wise, as my friend did. My advice is to get a charger specifically designed for and approved by Odessy!
I recently went to an EarthX, so had to scrap tha odessy charger and get one for the EarthX!

Jim-

Think you will be happy with the OBC-12A. It is on the recommended list for our PC680 batteries. One nice thing is there is enough amperage to leave the SkyView and avionics powered up for extended periods of time for software upgrades or while just digging through the menu settings for extended periods of time ... and still have enough reserve capacity to charge the battery.

After turning on the charger, I wait a few minutes until the charger switches from the test mode to charge mode before turning on the master switch.

Thanks, John-g. I received my OBC-12A yesterday and I will be trying it out today. I fly the RV-12 often enough that I doubt I will need it very often, but using it when I need to fiddle with the Skyview to give me a longer fiddle time will be very useful. There are cheaper solutions for this, I know, but I'm feeling pretty good about my selection of the OBC-12A charger with the battery protection features it has and the fact that it is sanctioned by Odyssey for my battery. If it does not work out well, I will certainly let everyone on this forum know about it.

Default cheap-o chargers

I would not use a cheapo charger, aka harbor freight, on an expensive AGM battery. It might work well for you or maybe not.

I bought several of these to use on my land toys in the garage and barn. 2 winters in a row I was gone for 3-4 months and upon returning home, after leaving everything on a charger, found one or two totally dead batteries. beyond resuscitation. I called the battery mfg and was told that when the charger fails, they sometimes turn into a load instead of a charger. I had to replace an AGM in the Wife's Miata and several 12v lead acid batteries that were fairly new.

All the cheap-o chargers went into the trash.

I use an Odyssey charger on my PC680. Works good. Last long time.

Was the Battery Tender described using over a twelve year period on the same battery? Was that battery an Odyssey PC680 by chance or something else?
I have used a different Battery Tender on the same battery for about 8 years and kept the charger plugged in any time I wasn't flying. The battery was in excellent shape when I removed it to replace with an EarthX.

I used this model https://www.amazon.com/Battery-Tende.../dp/B000CITKCE

An implied issue in the OP's post is how to prevent wrecking your battery while uploading data/software and learning/practicing buttonolgy and sitting in your hangar.

The recommendation to me, from a RV guru, is to plug in an 8 amp Battery Minder during the session.

As for the care and feeding and resuscitation of an Odyssey batteries, check out this thread and the post #22: http://www.vansairforce.com/communit...ey+care&page=3

Default Battery Tender

I just talked to support, Bruce Essig at at Odyssey, he says there are approved battery tenders on their website, along with chargers, etc.
