Odyssey TPPL Batteries

An interesting piece in this month's Sail magazine by Nigel Calder about his ongoing experiences with the Odyssey batteries. He is finding that they are losing capacity over time although it seems different from normal sulfation. He cut one open and didn't find the normal white crystals of sulfation. They looked perfect.

In any case, he has been experimenting with equalizing them and says the missing capacity returns. He is using really high voltages. Charging at 3-5 amps at 17 volts into a 100 amp hour battery for three hours. He saw no case bulging, excess heat or blown caps.

He's also concluded that these batteries should have much longer acceptance charges at 14.8V. Four to eight hours normally and an occasional 16-20 hours of acceptance voltage when plugged in to a dock.

This all seems pretty radical. Anyone have an opinion?

Re: Odyssey TPPL batteries

Can you tell me which months Sail magazine this was? Have searched but not found anything that discusses this?

Thanks,
michael

Carl,

I have seen the same thing on an Odyssey battery. Nigel and I discussed this, and I tried some of his tricks, and they seemed to eventually work on that battery. I used lower voltages though, at the suggestion of Enersys. The problem is that most of the folks out there don't own the equipment to do this and Odyssey still advises against it. I spoke at length with Kalyan J. one of the lead engineers at Enersys who agreed that they would replace the battery under warranty. I did this after that conversation and the battery came back. In the end the battery was still replaced under warranty because the boat is an off shore race boat and can't afford to have this happen again. The house bank of Odyssey batteries, on the same boat, had no issues what so ever.

In this case the battery was charged to 100% in the fall, mid winter and spring and had started the boat with ease into October. In the spring it was re-installed and failed to crank the motor.

The battery started out at just 16 CCA and came back to spec within four days of the rejuvenation exercise.. I was not using a normal charger for this and I don't think Nigel does either. I used a lab grade switch mode power supply with adjustable voltage and current. To do it with a charger you would need one with some fairly adjustable parameters.

Re: Odyssey TPPL batteries

thats all well and good - but I am still looking for the month, year and/or link that can show me what was written?

Very interested as I have an Odyssey battery bank - hopefully someone out there can send me a link or a summary of the conclusions & findings?

I had no idea Nigel even published that. I stopped getting Sail magazine sorry I can't help...

Re: Odyssey TPPL batteries

MainSail

My Odyssey's have not shown any noticeable decline after three years although I haven't done any scientific test. I'm using the "Crossed Fingers" battery management methodology.

My boat use tends to be used 10-12 days a month with a lot of engine use - so full charge and typically only 30-40% drained at night. When I'm not on the boat it's almost always on shore power.Probably about what the Odyssey's like.

I noticed that Odyssey makes float voltage a condition of the written warranty - I can't remember ever seeing that in a battery warranty. Trickle chargers that do not have a regulated trickle charge voltage between 13.5V and 13.8V (no lower than 13.5V and no higher than 13.8V) will cause early failure of the Battery. Use of such chargers with the Battery will also void the Battery’s warranty

I had read your comments about Lifeline's really liking regular equalization charges -- although not at Nigel's really high voltages. I was thinking that if he had no obvious problems at the really high voltages on the Odyssey then I would be OK at normal equalization levels like 15.5v. Obviously, this is an "at my own risk" exercise.

My charger is a Victron Multi. I've got the computer interface so I can set voltage and charging amps as well as monitor it during the equalization. Is there another reason for special charging equipment that I'm missing?

Thanks

Carl

Re: Odyssey TPPL batteries

I am close to buying these Odyssey Batteries to be my House Bank. ( 1000 AH )

I tried to find information on the recommended Battery Charger , 12VDC.

But found nothing. This was about a year ago. Perhaps there has been new

information published.

Any help and information would be appreciated.

Other wise will go with LifeLine Housebank.

Our usage might be similar; lots of dock time, anchoring only for 2-3 days at a time and only occasionally, usually depleting by only 20-30% or so when anchored (but sometimes to 50%, and a few times inadvertently to about 12.0v), twice daily charging (breakfast and dinner with an all-electric galley).

Our oldest 300-Ah bank (3x 31M-PC2150s) is midway through its 8th season. Coincidentally, I happened to check our batteries yesterday -- after full charge, and after 4 hours resting with no load and charger off. That bank was holding at 12.84v, measured with multi-meter at the bank. (Analog vu-meter in the saloon showed about 12.6v, but at that point there's also an immediate load on the system (CO detectors, shower sump for AC condensate, powered AM/FM/TV antenna, AC/DC panel lights, etc.) and probably some voltage drop from battery bank to saloon. And it's an analog gauge, with unknown veracity.

Re: Odyssey TPPL batteries

Please note that the largest size output from Odyssey approved Battery Charger is 50 amps.
How does this make any sense if you have a 1000 to 1200 AH House bank battery.

Sorry but I don't get it. Can someone explain this to me. I am thing a 90 amp output would be more appropriate but if this size is not approved ? ( max 50 amps )
What is wrong with this picture /

You don't need to have an "approved" charger just a charger that can follow the charging guidelines in the technical manual. It is impossible for Enersys to test every charger out there...

I like what Maine said.

There is a 60-amp one on their list (although that's not much bigger); ProMariner.

Re: Odyssey TPPL batteries

OK after 4 years of full time cruising my odyssey battery bank (2x1800FT, 12v 436ah) is down to about 52% of original rated capacity. It's time to either try the suggested charging regime or bin them and buy new.

What sort of charging equipment should I look for to try and bring some capacity back?

Thanks,
Michael

How was the current capacity tested? Details on this testing would help... That said four years of 24/7, with perhaps incorrect charging, is still decent life...
