I have home age 1202 800watt ups with phoenix 175 battery. both are bought this month. the problem is that the display shows me full battery but when the wapda light fails the first cell on ups display drops with in 5 mins of operation running only 60 to 30 watts. i bought the hydrometer to check the gravity. it was the day of pak vs ind match and the light didn't go for 24 hours so i tested the gravity of battery and it was around 1.240 to 1.235, I thought that it would be around 1.27 now is this right or not??? if not then where is the problem??? is ups not charging well or their is fault in battery? someone told me that we have to charge new battery from battery shops before attaching it to ups. the ups has 2 functions I have adjusted it to 15 amp charging. what to do???
