Ok, I have no idea about that...looking for a battery for a test...

A motorcycle battery (or other smaller engine, like a riding lawn mower, etc.) would be very similar to a UPS battery (but only for a test since most of these aren't sealed and will off-gas). A car battery could also work in a pinch for testing (but not long term, the capacity is much greater than a UPS battery, so running on it for a long time could overheat the UPS).

I have one old car battery 12V 70Ah....but I'm not sure, I think my wife has thrown it away...
For a test only....see if we can see a charging voltage or not...or my primary side has a failure...since the fuse had blown.....I don't wanna replace the fuse yet....not sure if my primary side is ok or faulty....bulb test later on with new fuse....
....there is but....the fuse is connected , 0 ohm but it has a sign of burn inside so there's a possibility that my primary side is ok...

That's good idea....diode on positive side ?
positive charger-----anode-----cathode---plus battery---battery----negative battery----ground .....?

NO
if you put the diode that way, the battery will charge, but the ups will never see it!

Re: opti ups 500 vs ii?

then how can I put it ?

Re: opti ups 500 vs ii?

anode towards the battery+
cathode towards the charger+
so the battery voltage flows towards the charger.

so the striped end of the diode goes toward the charger.

just hook up whatever 12v battery you have.
the problem only comes if you leave it in battery mode and it overheats due to no heatsinking.most of the cheap n nasty ones have a timer in the firmware to shut it down in a specified time.
skip the diode.

Re: opti ups 500 vs ii?

Since you have blown MAIN fuse so why are you bothering trying to hook up the battery, why not try to find if there is shorted circuit in the unit first?

Started from primary ?

Any schematic for this device ?

Re: opti ups 500 vs ii?

can it be tested without battery on it ?
