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).

if you look furter down on the specs for that device you will notice that the input is 12 volts but the out put is 110 volts, so unless you are going to connect the thing to a battery charger, then it will not do any good. i would look into a trickle charger for the thing and go that route, sure you have to use an extension cord and an outlet, but it will take care of what you are driving. either that or invest in a switch that will shut off the battery completely. i did this in a car that has been stored for too long now. it is pretty simple. mdk68gto, ase certified m tech
