OK I went the cheap AGM Chinese battery route, and it still works, but it needs some help from the charger now and then.
I am planning a trip away from chargers, or electricity for that matter, so want a better battery. The Shorai and the Odyssey both get good reviews here on a search, and they both cost about $160, give or take a few dollars.
What I most want is durability and cranking ability after being left in the cold for say 4 or 5 days. We might park the bikes and go backpacking or kayaking for a few days....want it to start when I return.
Is there much difference in these high end batteries?
If not, shipping to Alaska can decide for me...
Thanks.

You have to turn your lights on to let the battery warm up when its cold with that Shorai. No experience with the Odyssey.

?.... No experience with the Odyssey.
The Odyessy battery is a top quality, lead-acid, AGM, sealed battery.

I used them them in my BMW and H-D. No weight savings, big and heavy, but heavy duty military grade.

The Shorai in my TW has completed it's 5th season and is still going strong.

What kind of temperatures will the TW be left at? Lithium batteries do not like sub zero temperatures
I use a Shorai here in Nunavut but do not expect much riding after freezing temperatures hit.

Are you saying to turn on your lights and wait a bit before cranking the engine? How long do you wait?
From the Shorai FAQ's:

"


A. Down to about 20 degrees Fahrenheit (-7C) most users find that they can start normally on first crank. If your headlight comes on at key-ON, it is good for the batteries to flow some current before cranking in cold weather. The suggested headlight-on time before cranking depends on the temperature. If starting at 40F/5C, 30 seconds will help wake the battery and increase cranking performance. If at 0F/-17C, leave the lights on for 4~5 minutes before cranking. The result will be a better first crank, and longer battery life. If the engine fails to start on first crank, that first crank has warmed the battery, and the second attempt will be much stronger. Other accessories that can be turned on before cranking can also be used for this purpose, such as heated gear, radio, etc... Insuring that the battery is fully charged after storage also improves first-start performance in cold weather."

I use the Battery Tender lithium batteries.
Have them in one of the PC800s, the 10 Fatboy, TW and a few of the CB/CL bikes. The TW hasn't been started since may, went to the garage two towns away, and after connecting up the battery terminal, it started right up.
I have to get one for my 14 Ultra and one of the Beemers. Freaken BMW battery didn't even last a year. Went out there to take a ride (When I ride a BMW, I'm a douchebag, remember?) and all I got were clicks. So I had to ride the Fatboy (When I ride a Harley, I'm an asshole). I also took out a moped for a quick jaunt (I'm the guy who can't afford a real bike, LOL)

As long as there is no drain on a lithium, you can store it for over a year. On the Ultra, I'll have to pull the main fuse, as the computer seems to always be "on".
Never had a problem in very cold temps, as the headlights turn on as soon as you operate the ignition key on most bikes.

When Battery Tender makes or markets a 6V battery, you can be sure that my CT70s, 90s and other 6V bikes will have them.

It is tiring having to change batteries every year or two.

Yes same here, but plans may go out the window on a trip where the bike is parked outside and is the ride home. Could be forced to use it a little below freezing in a pinch...

Thanks for the good input. I think the cheap batteries are fine for day trips here, but I can sense a lot more reserve in the better batteries.
Of course if I would get busy and put a kicker in it would all mean less...even have some of the parts. Its on the list....

Have you thought about a kick start? If you are worried about a battery going flat a kick start would resolve that issue.

I have not been personally impressed by shorai's cold weather performance. I have one in my Ducati and since the nights have dipped to cold here in New England i have not been able to reliably get my bike to start in the morning and that is with it sitting on a tender to keep the battery charged. At this point after many non starts i don't trust it, needless to say that battery is coming out pronto....

Not too much comment on the odyssey here. I have had one in my R100GS for about 8 years now. Very pleased with its performance. The GS has a battery box the size of a lawn and tractor battery. The pc680 is abot 2 inches narrower than stock so I made a little box to fill the space and put a tool roll in there.

It isn't a light weight battery, but it has been a super reliable battery that has taken a huge amount of abuse. It has sat untouched for 3-4 months at a time every year (too hot to ride) with out a tender and cranked a stubborn GS back to life with no issue. Went a little over a year once with out a hiccup when called to serve. This GS has a crappy Valeo started that drags and howls if it has sat more than a week. The odyssey powers right through. If it ever dies i will likely replace it with a newer LiIPO4 battery but I don't know how long that might be.

i dont own either but a guy i ride one had ana odyssey in his klr for 10years and never put a tender on it then he sold it. If i was to spend that much money it would probably be an Odyssey for especially since Indiana winters can get way colder than what the shorai can handle. I think my $28 ebay scooter battery is about dead but for $28 its worth it if it lasts a little over two years like this one has

I had an Odyssey in my Vmax that was going on 10 years old, and still would spin that big v4 over in the dead of winter like nothing. A load test had it still pushing out over 90% of claimed CCAs, still working great when I sold the bike. I had similar good luck with one in my Z1000, 4 years old and still cranking like new when I sold that.

Lithium batteries and the cold don't get along. Down to about freezing they're OK, but start dipping below that and their amperage rapidly falls off. The "warm up" trick I have not found to reliably work.

I bought one of the Battery Tender Lithium Iron batteries and the recommended Battery Tender charger/maintainer. The battery died after about a month and a half. Amazon's warranty is for 30 days. Battery Tender replaced my battery after I paid to send it to them. They didn't tell me why it died. I'm impressed with the cranking power that little battery has. Never tried the AGM. Might have to on the other TW

I have made the plunge to the Battery Tender Lithium battery. The first one went bad. Contacted Amazon, thirty day warranty over. Contacted Deltran, the manufacturer, they replaced the battery. The second one went bad. I'm in the process of sending it back for replacement. I also bought the recommended charger/maintainer with the battery from amazon. Deltran said I have the right charger, but I need to charge the battery before putting it in the bike. So, we'll see. I like the weight and size of the battery, plus no acid to wreak havoc on metal parts. I still haven't bought a new battery for my older ('87) TW, and it needs one. Kick starter works fine. Thinking about trying AGM in it. Comments welcome.

That doesn't speak too well for Deltran batteries, but at least they replaced them.

Seems like they should have them fully charged when they send them out.

Especially on the replacement battery. The lithiums are supposed to hold a full charge for a year.

I was surprised as well. The service (phone) person told me they are 70% charged when shipped, and when I spun the engine over, I depleted the charge below recovery. I found that hard to swallow, but when I get my new replacement, I will charge it before installing so I won't be tempted. I can't fault them if I am doing something wrong. We'll see. Funny, you have to have a lithium charger, and can't charge a regular battery with a lithium charger. Just scratchin' my head.
