It was a Yuasa. I had an issue with a Yuasa battery in my BMW as well. That is when I contacted the company, The company does not do warranty. That is on the distributor or vehicle manufacturer. Triumph would not do anything without the original battery. It worked its way out of the bungee net, jumped off the bike at Chris and ran into the tall grass on a 2 lane road in MT. It eluded capture ... it was a bad battery. I paid for the replacement back home.
A very nice man at Yuasa told me that distributors will keep batteries in storage for too long and sell them on the web. That was not my case with the BMW. He ended up sending me a new battery for the BMW (substituted a higher capacity quad battery).

A well maintained battery on a bike lasts quite a long time.

Dunno...
GF's NT700VA always required 3~4 taps on the button till the starter actually turned the engine over... and even then it sounded strained...
Installed a new, fully charged OEM style AGM... no change...
Installed a new, fully charged gel type... same as above... turning over even worse (gel types show growing internal resistance under load...)
Installed a NOCO LiFEPO4... ah! Now we're getting somewhere... first tap, two rotations of the starter and it fires... always!

Hmmmmm.... that's strange. Sounds like you may have issues other than the battery...

Nope, because that was like 3 years ago...
Back then I checked everything*, switch-pods, relay, wiring harness, ground connection... nothing...
(* would be dull to get your GF a "new" mount that leaves her stranded every now and then... so I made sure that thing is in top condition...)

I've this battery still sitting on the bench, brand new, in the carton, only like 3 starting attempts on it...

GF got that herself, frustrated with the lame starting behavior of a (new) Yuasa YTZ14S... that gel type behaved even worse...

Threw the LiFEPO4 in, she's happy ever since... steady as a Swiss watch: "yup-yup-drrrrrr..." a satisfying sound

Call me conspiracy theorist if you want, but with the change of the millennium quality/lifespan of starter batteries declined massively...
Back in the 90ies the Yuasa YTX14-BS in my ST1100 lasted like 5 years... these days I won't even get two out of them... hence the change to LiFEPO4...
And if those really get discharged due to longer garage times, it takes only ~45 minutes to have them fully recharged again (with their small GENIUS5 charger...)

OK, if you insist.... "you are a conspiracy theorist......", there!


But, as they say, the proof is in the pudding..... if it starts her scoot straight away, and she's happy, what's not to like? You can't argue with success!

I had a LiFePO4 on my NT700 and it was the best battery I've ever used. Even after 8 years the bike would start on the touch of the button. The battery I used was the SkyRich HJTZ14S-FP

Yes, below about 3°C you needed to leave the lights and/or heated grips on for a while; the length of the "while" is temperature dependent. But you soon got used to turning the ignition on then putting on your helmet, gloves etc. And she'd start first or second press of the button even in temperatures as low as -10°C (about a 5 minute wait at that temperature).

After 8 or so years, in all seasons, and about 90,000 miles using a LiFePO4 battery all I can say is "Don't listen to the neigh-sayers."

I have been running a Lifepo5 on my FJR for the last seven years with no issues. Mine was bought from Advanced Auto Parts brand back then for 125.00 bucks.
