I have replaced my sukam 600VA UPS battery 3 times for only Rs.600 . Battery was also a quality exide battery. 700 battery cost - 100 for old battery.It is recommended to change the UPS after 2-3 years because the inbuilt battery usually deteriorates by this time.It is also more expensive to just replace the inbuilt battery instead of buying a new ups.
Let me check. Last time I asked,the shopkeeper quoted ~1100 for a good brand battery for 600VA ups.I have replaced my sukam 600VA UPS battery 3 times for only Rs.600 . Battery was also a quality exide battery. 700 battery cost - 100 for old battery.
