Does it start better / easier / faster in 'normal' biking temps? This is supposedly the whole point of the lithium, whereas 310 CCA AGM's struggle to crank over the big two jug fast enough. I mean, I use a 350 CCA in my 660cc UTV.

 

So far my NOCO is fine, but I dont have a high comp engine or big starter. I have the stock starter, and I live in the tropics, where it is always hot!!!. Im happuy with the switch to Li doubt i will go back Pb. But I will let you guys know my experience if it changes

 

Zero concerns when warmer (above 40 or sitting in sun on cooler day).
No hesitation. I don’t time it or anything, but works great. Push the button, engine cranks.
Also, not seen any drop off as I’ve thought with AGM.
The cost of entry also includes the idea that it will last many more years than a wet cell. Maybe too soon to see with the cycle industry (tho some of us early adopters will be getting there). But this has played out in the RV industry as LiFePo are proving to be much better for that power use scenario and lasting longer.
As costs come together, this will be an easier decision.

Any views on higher quality LiFePo batteries. Man, the Harley Battery Reviews scare the **** out of me. I see OP went with MoCo batt to test it. It does fit perfectly, no shimming needed, and does have balanced charging.

 

The OP did not go with a MoCo battery to test it. The OP has not purchased a lithium battery yet. But when he does it will not be one from HD.

 

Apologies - multiple threads going on the same subject, per usual. On one of these the OP did so such.
Getting frustrated myself. Maybe just get an upgraded AGM from 310 CCA Harley OEM to East Penn Duracell (Deka) 400 CCA.....

Don't get frustrated. I've read some of your posts, and it appears to me that you don't grasp the entirety of a subject and are easily confused. I'm going to take a stab at helping you here, with this subject. Your 310 CCA battery was fine when it was new, and it's become weak over time. This is normal. A new AGM will cure your worry, of that there is no doubt.

Now, do some research on the difference of what a CCA rating is, versus a pulse cranking rating. AGM = CCA, Lithium = pulse crank rating. They are not the same.

 

AFAIK that is a 30L format battery. It won't fit even to BM says it will fit a heritage.. IIRC you need a 20L format.. You can compare dimensions in the Specs.

 

I'm very familiar with CCA. We used it at work for decades. Amperage output of a new battery @ 0 deg F for 30 seconds.

What I do not know, and why I'm watching here, is why an AGM battery does not last as long in a motorcycle as in a car or truck. I don't get it. AGM lasts 5-7 years in automotive, only 3-5 max. in motorcycles. Why? My battery is going on 4 years this year. It is the original. A couple times last summer it lost ability to crank engine. I ride 3-4 times a week. I have to keep it on the charger. I didn't the 1st two years.

I also know trying to pack a tiny battery in a motorcycle means ampacity is critical for starting a 1746cc (in my case M8 107), two cylinder, odd-firing engine. 350 CCA is fine in my UTV and tractor - it is marginal in my bike.

I also know LiFePo batteries quit working at cold temperature - they can't be rated for CCA. But - they don't say at what temperature the amp output new is rated at, so you can't compare AGM with LiFePo @ 70 degs F, the lowest temp at which I ride. I get that tourers probably need an AGM due to the risk of LiFePo crapping out in the mountains, etc. I have read that owners get faster cranking with LiFePo at same temperature.

I also know battery space is limited in the little container under the seat. So we can't just be any similar battery - if it's too big. If it's too small, have to shim it.

I plan to pull my battery shortly and measure it. MoCo doesn't post sizes, probably to prevent aftermarket fit comparisons. Under battery Q&A, there were some size responses.
Stock AGM p/n 66000343
Q&A Replies:
CCA = 310
Size = 7.02"l x 3.34"w x 6.14h

Stock AGM p/n 66000344
CCA = 330
Size = 6.7l x 3.80"w x 6.10"h

For whatever reason, if AGM's last half as long as LiFePo in bikes, and lose cranking amps, it would make sense to me go with LiFePo. A perfect fit would be MoCo's, yet owner experiences has been very spotty with quality.

I don't see how there is any clarity here.
btw, the East Penn Duracell AGM recommendation is much wider, so probably doesn't fit.

 

Which is why I originally followed the battery thread instead of the touring bike thread. But I was advised to follow here. Thanks - I get my size is 20L. But even 'within' the 20L size, some makers aren't making to OEM batt size, so I need to pull the batt container from the bike to see if there is any extra room or not.

Hence, why this is absurdly frustrating to me. It's a fricking battery. Took me 10 minutes to figure out how to upgrade my truck battery to AGM.
