based on the load,your battery back up may determined.
for 600va inverter u can provide a maximum load of 460w(app.)for fan its 80w and tubelight it's 40w.
if your using 100ah battery,your backup for running the 2 fans and 2 light have load upto 240w is 5hours(app.).duration may differs based on the efficiency of the battery

((135AH*12V)/600VA)*85%Efficiency=2.20Hrs

PEPTELLER Inverters India's only branded company with LCD Display in Square wave inverter models 600VA & 800VA. There are many benefits of LCD Display. 1. Displays Load % while in backup mode: You can adjust your load to keep the load % at 50%. You will get double backup time. This is not possible with LED Inverter. 2. Displays battery status: You can know the battery charge status just like you see in the mobile phone. So, you can adjust the usage of inverter according to battery charge status and get backup when it is really required. 3. Display faults and their corrective measures: In case of Overload, the warning message of "OVERLOAD" is displayed along with "SWITCH OFF EXTRA LOAD". You can easily correct the problems. There are many more benefits. To know more: Log onto: http://www.pepteller.com Or write a mail to: marketinginv@pepteller.com
yes, old and new battery should have same voltage rating. Battery type shud match only capacity may be large.
600watts
VA stands for Volt-ampere. 1 VA is equal to 1 Watt. So 600va is about 600 watts. This can be confusing because a power supply rated at 600va will not put out 600 watts due to reactance. The power supply contains an inductor or capacitor so the actual output will be around 1/2 to 2/3 of the VA.
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
2.7A on the primary25A on the secondaryThis is easily calculated usingP = VIAs long as we make sure we use RMS values for current and voltage.

A computer power supply does not pose a seriously complex load ('complex load' in its electrical meaning); in other words, a computer power supply wattage (e.g. 550W) will be approximately the same as is VA value.However, a computer's power supply is typically rated after its nominal output power. Since it can't operate at 100% efficiency, the input power will be higher than 550W under maximum load.The power supply's technical data should tell you its rate of efficiency or its input power under maximum load, and you can chose the UPS accordingly.You could also chose a less scientific approach and justify the purchase of the 800VA, the 600VA, or even 400VA UPS: The bigger UPS will be overrated for this particular power supply, but might provided the better investment as it can support additional (small) devices and is likely to be sufficient in the event of a computer replacement (which might have different power requirements).However, the 600VA unit will probably be just fine for this particular case.You could also argue that the 550W power supply is a nominal power rating; it is the power the power supply is specified to sustain under full load. Your computer will very rarely come anywhere near this, and you could argue that high power number-crunching or DVD writing may not be required during a general power outage, making a less expensive apparently underrated UPS sufficient to sustain operations or data for the expected duration of a general outage.
