I too have been using the HD lithium battery for 2 years with no issues. The weight difference is amazing!

 

Its all good and only ting that matters are people happy with their purchase.
Im just trying to straighten out all the misinformation and misrepresentation many times right from the manufacturers of these batteries.

You do not have a 375 CCA battery. CCA IS the industry standard for all vehicle batteries. But these Lithium (as well as some cheaper lead acid) motorcycle battery makers mislead the public by using a NON industry meaningless CA (cranking amps) rating. Your battery is rated at 375 cranking amps which can mean anything. Not 375 CCA.
Again, Im not knocking what people chose, just the industry making people think they are getting a battery using a standard accepted rating of CCA in the battery world, used across ALL industries. Instead they are getting an EASY CA rating which doesn't even exist but more or less rated at 32 degrees instead of the industry standard of 0 degrees.

 

The newer lithium battery cranking amps are consistent from 100% SOC, all the way to 5%, and consistent to 32*. Currently, none of them have the CCA because of this chemistry. Until they resolve this cold temperature issue, I am told they never will have that rating. The battery distributor we have at work said it may be years until they have a powersports, or automotive lithium cell that can deal with those colder temps.

I am all about AGM batteries, and currently would never try one in anything but my Harley. It spends its cold time tucked away in my heated garage. Just wanted to see what it was all about, and so far it's been cranking my 128 at super speeds. It has a 3 year free replacement warranty, so that helped me justify the ridiculous price I paid for it. I also like Trojan and Optima batteries, so I am used to wasting some battery money...too many years living in Alaska, and being stranded in the cold one too many times when a vehicle wouldn't start LOL

 

Well specs state 420 CCA on the newer BikeMaster Lithium Ion 2.0 Battery BMP21L-FP

Your post is exactly my point. Please understand I am just explaining the mis-information out there and trying to help others. You point out Revzilla, thing is Revzilla (and many other sites are just plain wrong, heck these bimbos dont even know the difference between CA (which is a bullshit rating) and CCA (which is a real industry wide rating) completely incompetent.
All one has to do is go to the battery makers site instead of relying on incompetent or downright misleading motorcycle sites like Revzilla.
Here is a photo of the battery, right on the battery there is NO mention of CCA, only a pathetic 360 meaningless CA rating. Which would put this weak little battery close to 300 CCA with less then half the reserve capacity of a lead acid battery, Not even close to be a robust battery for a large cruiser loaded with accessories.

Lithium batteries as mentioned by someone else are capable of using all its energy more efficiently down to almost zero but the problem with that is, unlike a lead acid battery, you will never, ever know when the lithium battery is getting weak and about to die, it will sound perfect until it no longer will turn over the engine, leaving you stuck. Look, there is a reason major vehicle manufacturers do not use them and its not cost, the weight savings to a vehicle manufacturer would be terrific but for their size they just can not hold a lot of energy but the energy they do hold they can dispense almost down to the last volt, this still doesnt make up for the lack of capacity and terrible cold weather performance.
Just so you know, I am not knocking anyone buying these things for the fun of it. It is kind of cool but people need to know what they are buying is all I am saying. Wait until all these lithium batteries start crapping out in another year or two with no warning, leaving many stuck. For such a pricey item, you are getting way less battery but more "fun" factor and thats ok, as long as these website correctly display the information that people are using to buy these things at these crazy prices.

^^ Amazing power output but the price reflects that. Lots of advertising in the website, words like twice the life of lead acid but they cant prove it with a weak 3 year warranty on a $500 battery.
Also the CA rating is a BS rating of 970 which would put it around 750 CCA for $500 ... but if weight is a concern maybe that is all that would matter to someone.

My Sams Club Duracell Marine Lead Acid Battery for our boat cost $100 with the same rating.... 1000 MCA and 800 CCA.
My Motorcycle Mega Crank cost $100 for 425 CCA 300% more reserve power too and I will throw it away in 3 to 4 years before it goes bad.

Now we just need someone from this forum to buy one and give us a yearly update.
