What car battery charger/maintainer would be most ideal for a backup power setup?

Hello,
I am working making a battery backup setup usually called a UPS (uninterruptible power supply) using a power inverter, a car battery and a battery charger.
I am likely going to use http://cgi.ebay.com/OSP-1500W-PURE-SINE-WAVE-POWER-INVERTER-DC-AC_W0QQitemZ350267893228QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item518d97e5ec this inverter. It delivers pure sine wave power which is what I need as I am going to be using this to power electronics such as a computer and a projector. I am a little lost on which battery charger would be best though. I’ve seen something called a ‘battery tender jr’. But I don’t know if that would be best.
It sounds ideal. What I’ve learned is that I probably want a float charger with an option of either manually or automatically once in a while charging the battery to it’s maximum for a few hours to enable longevity in the batteries life.
Any input would be appreciated.
Thanks!
I don’t think I understand your answer. It sounds likely that we aren’t on the same page as to how this is set up. Plugged into an outlet (120v)is a battery maintainer, it is then connected (12v) to a battery. The battery (12v) is connected to a power inverter, and then the inverter powers devices(120v).
