Re: FortiToken 200 battery life
Well, it depends .. the most power hungry part in the FortiToken 200/200-CD/220 is display.
Therefore if you use it occasionally, then it will last longer then heavily/actively used token.
Safe guess is 5Y battery life approximated to roughly 14000 cycles.
So, I would keep it till it fails. With this scenario coming kept in mind, and with safe way/backup account or whatever suits you to be able to regain admin access to the protected unit even without the token.
