I have never used a UPS so I have a few questions regarding them. My main requirement is running my PC (around 400W and a fan) for about 2 hours.
I went to this desi UPS shop and after telling him my load of 500W he recommended the 1000W UPS for me, I bought it on his word and now thinking of buying the batteries, as I am no expert in this I have to ask here.
1. Is it ok to buy a 1000W UPS for a 500W load?
2. What batteries do I need? The guy told me to get a 200amp battery, but after reading the forums I read that the rule of thumb is to have 140amp batteries with a 1000W UPS? Can't I get the 200amp battery? How much backup should I expect with the 140amp vs the 200amp battery.
3. Which brand to go for, wet battery?
