Odyssey AGM battery - Will my old trickle charger still work?

[Keith Newby]

It should work. I use a "battery tender" trickle charger on all my batteries, AGM or flooded without issue. I think the only time you need a dedicated charger would be for Lithium Ion batteries.

.....I have owned Odyssey batteries and run them in my motorcycles and my vehicles.

The tech help guy at Odyssey told me that their batteries require a little bit higher voltage when charging compared to other AGM batteries and other lead acid batteries.

He said if I did not use their maintainer, the Odyssey would not perform optimally.

I ended up buying their big charger and their smaller maintainer.

I ended up switching to LiFPo batteries in my motorcycles and have other AGMs in my cars.

I don't know if the Porsche/Ctek will hurt, but I do know that your maintainer should be one with an AGM setting. I have a Ctek with that setting. I think the Porsche "Pro" model does, also. It's a tad bigger than the original Porsche branded CteK one they first offered.

Soooooooo.........Yes, but I didn't actually notice any real benefit to the Odyssey charger overall as I switched to Li-ion soon after.

I know that doesn't help much, but FWIW, the Odyssey guy said you should. But then you would expect that. Their charger DOES indeed charge to a higher voltage, so I did see that.

I have used cteks (motorsports version and basic version) on Odysseys (PCS 925) for years with no apparent ill effects. In fact my current one may have been in service for 7+years. It was load tested a specialty shop a couple years back and had no issues.

I have the car plugged in most of the time it is sitting and really take care of it though.

Yes I am probably running on borrowed time

I used the simple ctec/Porsche-labeled no buttons model on an Odyssey in my '01S for at least 5 years and it did a perfect job in that it kept enough of a charge on a battery to start the car in cold weather but that battery was in a car where the battery was always fully charged when stopped.

Since I had a separate charger from the same era, I used the charger on any run down batteries and saved the maintainer for hibernation duties.

Optimal, maybe not. But it worked for me.
