Hello everyone about a year ago i purchased a good battery for my kangertech mod. The mod sat on the shelf gathering dust for awhile because I couldn't afford to buy a coil for it. I recently bought one and started to vape on it. I noticed that the battery life has significantly decreased, one full charge used to last me for 24hours or sometimes more. Now I am draining it twice a day! vaping at only 25 or 30 Watts! Has this battery degraded over time? Is it bad for my mod to continue using it? The only difference I notice is the battery life is significantly reduced. It is a year old battery. (I bought it a year ago)

Degradation/aging seems most likely as long as you're using it the same way you did at first. In other words, if you've increased your wattage or vaping time from a year ago that would also explain it, but if not it's probably the battery. Batteries age both with use (recharge cycles) and over time, even without any use. That's especially true if the battery's just been left sitting for more than a month or two. It's best to store 18650s with a partial charge - about 3.6 V. They'll discharge over time, so if they're not used for a time you can take them out periodically to bump the charge back up to 3.6. If the charge drops too low they'll degrade faster, which may be what happened to you.
ETA: The other potential issue is the age of the battery. One year isn't terribly old, but you never know how long the supplier had it before you got it.

What kind of battery is this?
If stored properly (40-50% charge or around 3.6-3.7V and at a comfortable temperature) a battery should lose no more than 5-10% of its capacity after a year.
I still vape some batteries that are 3+ years old. Are they as good as when they were new? No. But they're still quite usable.

I have batteries over a year old that have lost a little bit, maybe 10-15% if I had to guess. They get used a lot too because I only have 4 batteries that I rotate in a dual battery mod. Your batteries shouldn't be that bad so I think something happened. Maybe you left it on last time you used it and the battery drained way too low. Because if it was just sitting and was off you shouldn't had such a decrease in performance. You could continue using, I don't think it's dangerous, just the annoyance of having to recharge more often.
This.
I also have a couple of three year old batteries that are still working. I never put more than 5A on them now, but they still take and hold a charge.
It sounds like the battery in question is being put under a higher load than before. Maybe the wattage has changed?
While going through some boxes of vape gear yesterday I found one of my first 18650s in a plastic battery box. It's probably been 2 or three years since I charged it, but when I stuck it in the charger the display read 4.2v and the charging indicator was cycling. It's an old button top that I used on my Provari. It's been sitting in the box for a while.

Of course, there are many battery chemistry variations with different levels of ageing and deterioration.
Stored at a maximum of 14/15th of max charge voltage (3.92/4.2V) in a cool and dry place batteries should last a lot of years with minimal detriment.
