i have been exclusively using mech mods from last few months and started using my new 18650 along with that .... after about 6 months i am feeling that my batteries need charge more often then it did when new or up until last month..... so was wondering how long you guys use battery before feeling the need to replace it ??
How often you buy a New Battery !!

most li-on batteries will have a useful life of about 250 charge cycles - this # will be greatly reduced if they are consistently discharged below 3.3 volts (which can happen in mech mods)
I replace them about when that happens. Usually 5-6 months of steady use of a pair of batteries.
i buy new ones when i see ones i fancy with appealing specs. Current rotation has Samsungs, mnkes, and orbtronic 2900pds and some orb sx30s.
I have 10 or so AWs and Efests, but finding which are sagging after 6 months of sub-Ω abuse is more time than i am willing to spend, so i'll toss the lot. If you run a decent mech then never short sell yourself on cheap batteries and chargers, the difference between good and dismal is a few cents a day over its lifetime.
What happens to a battery over time is that its internal resistance increases and it is less able to hold voltage for any time. Time for the bin.

I only use egos nowadays (Li-On) and rotate 2 throughout the day. 5-6ml per day. Sometimes I run them down, other times not.
My latest 2 Joyetech Upgrade Passthroughs have over 1-1/2 yrs on them and going strong. They fully charge and hold for 6 hours as when purchased.

I have two VERY RELIABLE batteries..but I am sure at some time they will give out...I want to have two more ready when that happens
I have 8 x 350s, 8 x 490/500, and 4 x 650s - I hope that they will last me a year and a half - have been using them for 3 months and no degradation in performance. Have discharged one or 2 below 3.0, but only once or so.
I'm still using 11-21-2011 18350s that have been through countless cycles. They hold charge about half as long as my 2013 18350s. I'm yearning for them to die so I can toss. If cost no concern I'd replace annually.
I get anywhere from 200-250 charge cycles from a battery before it shows signs of capacity loss. Then I replace it. I've been vaping with Li-ions for over two years and have two APVs that have outlived the batteries used with them.
A good IMR has an average cycle life of 500 cycles, provided that they are properly used and cared for, ie: don't discharge below 3.5v, recharge asap, store at the proper voltage (3.7-3.9v) when not in use. Do not store your batteries at full charge (4.2v) for an extending period of time.
You can extend the cycle life of IMR batteries by not charging them to 4.2v, taking them to 3.9v instead, which can increase cycle life to about 1000 cycles.
I have not had to "replace" a battery because I take good care of them, and rotate my use of them, as opposed to using one pair to death. I also label/date my batteries to keep track of how long they have been in use.
