That's why im aiming 150ah at least to just get through.

What is the power draw your doing on your system?
i was running 55" telly, laptop, yamaha amp and various little USB chargers etc for 2hrs load shedding.
but i have since then disconnected my batteries from UPS and now in survival mode in case load shedding gets a lot worse (i dont need to watch tv while there is load shedding etc)

so now i only have my fiber box and wifi router connected to the batteries, I cut the AC-DC Power supplies off and connected them straight seen as they are both 12v, i manually recharge the batteries each Sunday night when i see the voltmeter showing 12.5v on each battery.

You could get away with a lot less if you not so persistent to have the gaming PC running in that 2-3 hrs. Sure you can have it on but why exactly must you be gaming? ... my gaming PC runs during loadshedding and only draws about 120-150W

That doesn't sound to heavy, why only 2 hours then.

If i'm calculating this right, my power need will be 600-700 ( 700 watt being worst case if it's ever going to reach that ) and i'll probably get 2:30 maybe 3 hours depends on TV or computer being on. Then longer

tv brightness setting makes a big difference too.

Idle or light browsing and usage?
What system specs do you have. As well what battery and inverter do you have.

i get 2hr 10min load shedding slots at a time in Somerset West
i have always been a firm believer in not allowing a lead type battery to deplete below 80% battery level.
its just me
im anal
but as a result my lead acids last a gazillion years

Oh so you keep them on 20% usage only

worse case scenario yes, i have them in series for 24v and when the voltmeter shows 25.0v i put them on charge (happens every Sunday night)
i also have a small LED light strip i sometimes put on in the lounge, but not very often.

im keeping my loadshedding needs to a minimum and my batteries topped up to the max in prep for Winter as i reckon we are going to be in dark many times this year

if you have 24V, how do you run 12V device?

Yip, light browsing as I dont see the need to be gaming during loadshedding ... you read a couple of MyBB threads and BOOM, you look again and loadshedding is finish :p

Im running a 12V 1KVa Axpert inverter with 2x 100Ah Gel in parallel ( Batteries needs replacing after 4½yrs as noted previously in this thread ), so Im also on the lookout for replacements.

It's my entertainment to game, my wife enjoys watching her series on netflix. I get bored of netflix quite quick.

I'm sure games like dota2 don't use 400-450w , could be wrong. Those omnipower 120ah are heavy, it's hard to buy them and ship, shipping is rough.
