OK, so my battery is starting to read in the lower 12V range no matter if it sits on a battery tender or not, typically 12.1 to 12.4 but even as low as 11.9. I think it's time for it to be replaced. Does anyone know if H-D updated the new battery for the 1st Gen Pan Ams to have more CCAs? I swear I remember the originals being 225 CCA but reading they updated the replacements for the 1st Gen PAs to be 240 CCAs. I also see the part number has changed but I can't seem to find anything about a battery change besides the 24 PAs getting a larger battery. Does anybody have an idea on if something changed?
Thank you in advance for any insight!

 

CCA is not battery capacity. If you want capacity look for AmpHours.

 

Yep, I threw capacity in there on accident, removed.

 

The changes were more than just a battery. For 2024 they changed the electrical system by including a bigger battery, yes, but also the charging system has some changes.

Apparently you can retrofit a 2021-2023 Pan America to the new 2024 charging system.

Here's the service bulletin.

REVOLUTION MAX CHARGING SYSTEM SERVICE KIT

Now, unrelated to this, some Gen 1 owners have reported significant reliability increases by installing a higher-power lithium battery, by itself. But if you want the complete fix, you probably need to add the whole service kit. Looks like it's in the ballpark of $2600 or so.

 

I'd read it was expensive to update the 21s-23s with the electrical system from the 24 models. Non-OEM replacement batteries are listed at 220CCA, so maybe that's the mark the old OEM batteries are hitting.
I'd switch to lithium but was warned by a H-D service dept employee that it'd void my ESP/warranty. That's why I'm looking at AGM batteries, including the standard H-D replacement. Finding the CCA for the revised part number on the H-D battery is impossible.
I'd read somewhere it had been upped to 240CCA but I can't find it now. I swear, whenever I need a little info, H-D acts as if it's vital to national security and has it marked as "for Zeitz eyes only".

 

The battery part number for the 2024 Pan America is 65989-97E.

For the 2021 Pan America it was 65958-04C.

Website is scant on details but it does show the amp-hours is a huge increase. 2021's was a 12Ah battery, the 2024's is a 17.5 Ah battery.

From https://h-dmediakit.com/jp/bdp/?ra1250s|2021, it shows the 2021 battery specs as "Sealed, maintenance-free, absorbed glass mat (AGM) battery, 12V, 12Ah, 225 CCA at 0°F".
Unfortunately, it looks like they copied and pasted the specs for 2024, it reads exactly the same, despite us knowing that the 2024's battery is 17.5Ah is nearly 50% more.

Can't find any definitive details on the stock 2024 battery's CCA. However, in this video, Mike's Motorbike Channel says the 2024 battery is 315 CCA. From what I can tell, Mike's considered to be "the guy" when it comes to Pan America knowledge, and he's the only guy on the entire internet (seemingly!) who quotes a stat at all, so I'd tend to say he's probably correct.

 

 

I headed down to the dealer today and point blank asked, it took the parts counter 10 minutes to find the info on the original OE battery. You're right 12V, 12AH, 225CCA. He then found the new part number for the 2021-2023 models and stated nothing had changed. I won't be buying an HD battery, this one only lasted 16 months, the shortest life of any motorcycle battery I've ever had. He did say Drag Specialties makes one (GYZ16HL, Revzilla is calling for this battery too) that fits and is an AGM so it won't void my ESP/warranty. I looked it up, the dimensions look to be slightly larger than stock so I have no idea if it will fit.

Has anyone here used the DS battery or know of another reputable AGM battery that fits the Pan Am? I swear, H-D is going to force me to go with Antigravity. I don't have a lot of trust in lithium batteries after having a rechargeable lithium flashlight go Chernobyl a few years ago, but I don't want to swap a battery every year or so either.​​​​
