While somewhat specific to older BMW motorcycles, this article (probably many of you are familiar with the source) offers an in-depth look at batteries and their lifecycle.

You might find it useful / interesting. Or not. YMMV.

Battery story.Here's a remarkable true story about my first Optima 1000cca redtop for my Dodge cummins. Bought in 1991 when my original died I had not heard of Optima. Guy at work was getting "seconds" and selling for $60. That battery was in my truck for 17 years before wouldn't crank. So into my 55 Buick century where it went 3 more. After it wouldn't crank I made a bracket and mounted it on my riding lawnmower.5 more on that and it gave up for good. Too bad they don't sell em for that much anymore.

Must have been one of those made in America Optimas. They are complete garbage now. Schneider bought them out a decade ago and moved production to Mexico and they have been shit ever since.

I replaced mine today. Had to use quick charger a few times this year but that may be partly from age and partly because I do not ride much any longer. Bought the battery in March 2017 so that seems pretty consistent with what is posted here.

I have since wired in a battery tender, with that you should be good to go for years I would think. I am interested in what others think about this.
I run a battery tender and it usually lasts years.

I got just over five years on my first Yuasa AGM, replaced it with the same and Iím on almost fours years and going strong
I use a battery tender when the bike isnít going to be used for more than a couple of weeks, mainly during our wet Winters.
I also donít commute regularly on the bike, so when I go for a ride it is typically most of the day which allows the battery to get a solid full charge.
My previous bike was older and had lots of battery issues due mostly to heat issues (poor placement) and some electrical issues that I eventually resolved.

Just replaced it. Took me an extra day because the directions said to NOT add the electrolyte if over 86 deg. F. Since it was about 102 in the garage I waited until things cooled off. Don't want a face full of acid. I grew up with a kid who had gotten one and it wasn't pretty.

Well this has been my experience with Moto-Batteries.

87 FJ1200
OEM Lead-Acid Battery. 20-30 Months between replacement. About 24 months on Average.
Bikemaster Gel-Type Battery. 48+ Months. Battery was installed in Sept 2010, and the current owner replaced it sometime in 2014.
12/17 Ninja 1000's
OEM AGM Batteries. I believe that the current owner replaced the '12's OEM Battery either in 2018 or '19; and my 17's OEM battery is still going strong.

Just my .02.

If your only getting about 2 years out of a bike battery, my guess is that you've been using Lead-Acid batteries. There's really nothing wrong with doing so, but most modern bikes are now coming with AGM batteries. AGM batteries usually last a lot longer than both Lead-Acid and Gel-type batteries. Unfortunately, that extra durability does come at an additional cost (upwards of twice the price of a lead-acid battery). However, a good, quality AGM Battery should get well over twice the lifespan of a good, quality lead-acid battery, and should last at least a year or two longer than a Gel-Type. Additionally, AGM batteries are quite often cheaper than, and have better cold weather performance. than Gel-Types. In a nut shell, though Lead-Acid batteries are cheaper in the short-term, AGM batteries are cheaper in the long run.
