The first one died after 4-years - the second is now showing signs of dying at 4-years...

I bought mine thru Pep Boys (the lowest price, especially with an online ordering discount)... Current price is $88.99 - 20% discount = about $72.
Good price, one year warranty; but locally, Pep Boys closed their parts sales (partly induced by Covid panic), opting to do only service. The Pep Boys link indicated not available to ship, so might not be able to obtain here.

By comparison

O'Reillys only shows a lead-acid for $59.99 3 month warranty

AutoZone has Duralast AGM for $109.99 and 3 month warranty

Napa AGM is $102.99, ship to home and 6 month warranty

BatteryMart Big Crank AGM is $104.95 and 1 year PRO-RATED warranty

BatteryMart Motobatt is $132.70 and 1 year (non-prorated = free replacement) warranty

BatteriesPlus AGM $129.99 and 2 year warranty

Not sure all below links are correct battery for 1983, but should be suitable for comparison of price and warranty

ON H-D website, not set-up for earlier than 1984, which is $130.95, but did not find warranty info.

https://www.harley-davidson.com/us/e...ry/p/65991-82B

Dennis Kirk and JP Cycles are comparable, but I would prefer to go to a store if a warranty issue, so BatteriesPlus would be a consideration...or the Mo-Co, depending upon warranty and availability.

My last Deka ETX14 lasted 8 1/2 years. ETX14 is just a smaller version of the ETX16. 220 CCA vs 325 CCA.

I also use the Deka ETX30L 400 CCA in my garden tractor. It's going on 3 years. No problems.

Bottom line..... if it was my ride, go with Deka ETX16. And if that croaks on you too, I'd suggest you got something else going on in that charging system. But hey you know your ride, I do not.

https://www.summitracing.com/parts/ysa-ytx20h-bs

WTF!?!? Are they sealed or open and require filling??? One of the customer comments says that "battery comes dry. Best results when you add the liquid and let it sit 2 hours BEFORE throwing it on a charger. Low amp charge overnight is best".

This site [Summit] is the only one of a half-dozen I've read that states that the Yuasa AGM requires filling...

95% of the batteries we sell in store are sold dry with the acid included in the box. Very simple to fill the battery with the enclosed acid pack. There is then a sealing strip that seals the battery making it sealed and maintenance free. The old guy who works the counter says to leave the top off while you charge it and then seal it. Slow charge. 2 amps or less. 8 hours or so.

The problems I had with the AGM's were probably related to size.

As I was using them in a dead loss ignition only situation I used "small" (9 AH I think ?) batteries. The drain sin't that much and I could swap in a spare fully charged battery in about 2 minutes.

The problems you face with the smaller sized batteries is that internally the plates and frame that holds the plates are small. Too small for the vibrations inherent with a Sportster powered sidecar. The platess would vibrate, touch and even break.

After too many problems I went to Shorai and their technical department worked out what was happening to them for me.

I asked them if they would garuntee one of their LION batteries would hold up. They refused to garuntee it because it had not been tested for those conditions.
But I had no problems after switching to Shorai batteries.

Expensive ? Yes. Each battery set me back $200 plus I use their chargers - ($180) on them - just to be safe.

But over the 6 years I have used the two I bought, no failures - so cheaper than a new battery for every race meeting using AGM.

Just be aware under the wrong conditions these LIONS can catch fire. To see the results of those fires check out all the videos of Tesla's on YouTube.

After a couple hundred years you would think we would have batteries that store more power, are smaller and cheaper that last at least a decade.

We can build Hypersonic missiles to deliver a nuclear bomb but out batteries still need you to fill them with acid, add water and be very careful how you charge them ?

Does anyone really know their ride??? After 37 years, and a dozen or more owners, can I be sure of anything on this XLH??? The speedometer showed only 14,140 miles when I got it. It's obvious that someone has recently done a lot of maintenance on it. The tires are not even worn yet.

Going back over my notes, I see that I actually ran the engine up to 4,000rpm to check the Powerraythor 65A alternator/regulator, and when it hit 2,500rpm, the charging rate remained constant. Battery was 12.88v fully charged (by me) when I put it in (static reading).

RPM Volts
0 12.37
1000 12.84
1500 14.42
2000 14.43
2500 14.44
3000 14.44
3500 14.44
4000 14.44

The static voltage was 12.80v after the run. It was 12.66v next day, 16 hours later.

I'm still looking at batteries. Oddly, Wal-Mart shows two Yuasa YTX20H-BS batteries, both for the same price - $99.99.

I like that Deka EXT16 at Pep Boys, but the site says "...not available for Shipping". Hey! There's a Pep Boys only 5 miles from me! There never used to be??? I am heading there soon...After the banks open again...

Ooh...325cca...I like that...Hey! I know that store! It used to be a Speedy Muffler store! I stopped in there once to see if they could weld up a SS exhaust for my Vette. Wonder where they went???

"I pulled this from a battery comparison. I've had people tell me that AGM's require a reliable and consistent charging system. So if you have an older style charging system, it may not be recommended for an AGM battery. Write AutoZone a letter, they may just refund your money or give you a free replacement or in-store credit."

Good advice. I only add that you may consider using Lithium Ion battery if your charging system is sound. I use one in my FatBoy for 4 years without issue and it weighs maybe 6lbs vs 18lbs for AGM or Flooded Cell types

While voltage gives you an indication - it's not the whole story.

At 12.6 volts a LION battery would be considered as 70% (maybe more - I forget ?) discharged.

And an AGM or lead acid battery showing 12.66 volts may not have enough amperage left to start the bike.

I think the YUASA's come in either the old "fill it yerself" style or sealed from the factory style. I thought there was a minor difference in the part number though.

In a way, having a dead battery was a blessing for me. Measuring voltage or continuity is pretty much the limit of my abilities, electrically. If it had been a short somewhere, or a bad relay, or a solenoid/starter problem, I'd be clueless. I doubt if I could even follow instructions on diagnosing an electrical problem.

I can wire a house or garage but a motorcycle??? Forget about it...

well, the duralast is a china product mfg by clarios llc
they also make the die hard which adv auto bought from sears.
deka makes the hd battery and i use them but the hd battery goes a year longer, i guess hd holds their feet to the fire.
i tried the wet lead acid battery and it was a flop, actually boiled over and the acid messed up a pair of jeans. a seal unit is the way to go, at least for me.

Well Clint, this is why we get problems to solve. Every time we solve one we move our limitations farther out.

But if we do move our limitations to far out, we can lose sight of them.

Then we can run for an elected office.
