YUASA 12 volt Black 75AH 740A batteries carried a lifetime warranty. That has now been withdrawn. Such a battery was purchased April 2018 & used in a circa 1929 Alfa Gran Turismo, last used for events October this year. Car has battery isolator switch, along with a clean power battery desulfator, with battery isolator switch utilised when car not in use. Car last taken last October. Check early December revealed battery would not turn engine. Checks of car electrics & battery replacement with old spare started engine, confirming no problem with mechanics. Battery charging with Ring charger, with cut out on charge completion, has revealed drops in volts & amps (show 300), with rapid dropping when charger disconnected. Retailers reported manufacturers voided guarantee. Manufacturers terms on internet contain exclusions including Sulphuration. Battery is a sealed one, so not possible to check battery internals, leaving question whether a battery which has been disconnected from car electrics & with fitted & working Desulfator , should fail in this manner (current amps after charging show 300A, & 14.5 volts, both rapidly dropping when charger disconnected indicative of serious battery fault, with further questions over whether internals including plates manufactured & fitted to standard to meet a lifetime guarantee, against more normal limited lifetime guarantees of between 2-5 years ?

Are you real?
Are you saying that in 2018 when you purchased the battery it had a lifetime warranty, and now said warranty has been withdrawn? Or that now they don't come with lifetime warranties? They can't do that unless they give you your money back for it.
The battery is the battery, and the warranty is the warranty. There isn't any difference between a lifetime warranty battery and a 3 year warranty battery. A battery manufacturer or retailer that offers a long or even a lifetime warranty (even JC Penny offered a lifetime warranty back in the 70's) doesn't mean that the battery itself is going to last any longer than any other lead/acid battery, all of them will fail within a limited time frame. Most of what I have read (and my personal experience) indicates that desulfators either do not work at all or provide very limited desulfation. Personally, I have had the best luck keeping a battery on a constant voltage charge and setting it to 13.2v to 13.4v, this will stave-off sulfation better than a desulfator.
Did you buy this online or at a B&M store?
Do you have YOUR warranty, on a piece of paper, from when you bought it?
I'd take it back, and don't take no for an answer. It's not sulfated. It's not undercharged. It's bad. New one, please.

the Yuasa ybx9 are AGM, so in your case that would be YBX9096

Hey, if movie scripts are going to read like this, I'm glad the writers went on strike.
Long live flesh and blood.
According to the retailer the manufacturers voided the guarantee & no longer is a lifetime guarantee given. Reliance is placed on their manufacture terms which exclude what they claim as non manufacture failings including sulfurisation.
One would logically expect one with a lifetime guarantee would be of superior quality ,against one with limited guarantee, but being a sealed unit inspection of internals, topping up etc cannot be done. Suffice battery found to have failed some one month or so after car last used. That car has battery isolator, thus when used isolating battery from car electrics, along with a clean power battery desulphator (among best reported in 2021) should ordinarily suffice to protect battery from failure . Car battery charge(Ring) in use with cut out to prevent risk).

This was a 096 Black 12 volt 75AH/ 740A Battery with a lifetime guarantee when purchased April 2018. Neither retailer nor reportedly does the manufacturer now offer such a guarantee. Assumption both now recognise it is not viably economic.
primarily issue remains as to cause & whether such a warranty is a viable prospect or, as you put it, a gimmick. Naturally one would expect a superior quality of manufacture, but then with a sealed battery, internal inspection to determine cause, not possible.
The fact remains the battery was found to have failed some 8 months into it's 5th year of purchase. If it is correct such a warranty cannot be met, regardless of steps and precautions taken against failure, then it follows such a guarantee is not worth the paper it is written on, but it would b interesting to know whether it has ever been met, or what had transpired, should action have been taken to question a decision to void the guarantee.
The question remains whether, given the numerous exceptions to responsibility contained within a manufacturers warranty, as to how complainants have fared in practice, & whether there have been any successes in recovery under what was a lifetime guarantee, given tendency for assumption unless failure is shortly after purchase, manufacturers assumption not their fault & exceptions applied.
That's not how guarantees work. The longer the guarantee, the higher the chance you have to replace and the cheaper you have to make the product and the more expensive you have to sell.
But have you contacted Yuasa? It seems to me all you have is what a salesman told you?
Everything that I'm seeing is that Yuasa as a manufacturer offers only a very limited 6 month or one year warranty to the consumer, and in some countries such as the USA they leave the factory with no warranty at all. Dealers are allowed to offer a longer warranty but that is entirely at the dealer level. The Internet is not rife with complaints by others of a lifetime warranty being withdrawn. I didn't find any evidence of a lifetime warranty ever existing.
