The 700 W rating is the maximum load that can be used from the UPS
without any damage to it, or it with it being over-loaded. Normaly, the
maximum load should not exceed about 60% of the maximum capacity of a
UPS.

In the instruction manual for the UPS, they usually give a chart of how
long it will supply power with different loads. The effect of the load
may not be exactly linear because the load is being run from an
inverter. This inverter itself uses a certain amount of base current to
operate. It's efficiency may not be very linear.

In theory, a 120 Amp Hour battery should be able to put out 120 Amps for
one hour. Normaly, when a battery is under load, when the voltage of
the battery has decreased to about 10% below the nominal rating of the
battery voltage, the battery is considered weak.

Most battery manufacturers specify Ah capacity for the 10 hour discharge
rate - a 120Ah battery loaded at 120A will be discharged in somewhat less
than 1 hour.

If they are working to US SAE specifications it is 20 hour discharge.

Just get a GMail account. I use it without munging all the time. I get
thousands of spam messages piling up in my spam folder, but I can't
remember the last time that a spam message reached by inbox.

I've just unblocked Gmail after blocking it totally because of the amount
of spam that originates from it. And I'd guess others do the same. And the
amount of spam coming from it appears not to have reduced so I'll block it
again.
Anyone who has something interesting to say of these groups usually gets a
reply so I'll see the original that way.

Gmail is not the same as google groups. I use a gmail account for my
email, and you can set it as the reply-to address, but I've always used
my Verizon account to post usenet messages. I quit using ISP email
accounts after my ISP changed names 2 or 3 times in just a couple of
years, got sick of constantly changing my email address.

Hi,
I'm using a 700W UPS (localy made)

Just out of interest, of what value is the information "(localy made)" <sic>
when you don't mention what part of the world you live in ?

Or is it the 'world' called the USA ?

I'd say he made it himself...
