How long........

[Defib]

Hi folks

I purchased another UPS, 850VA line UPS

Could anyone tell me the way to work out how long it will last with X amount of watts?

Say for example. Appliance 1 is 10w Appliance 2 is 30w and so on....

I am also not sure if i should fork out for a new SLA for the 650VA Sahara unit i have. I will see how to work out my above question and decide from there.

Thanksbin advance, not my strongest point

There's a calculator somewhere. Search. User 'theStranger' posted it.

Those Sahara units are not that good. I bought one and after a couple of loadsheds a 6 watt led don't even last 2 hours

Looking to replace the batteries with better ones.
