Ups battery acid gravity is 1200, low backup

[ftb7007]

AoA, My 160ah Ups battery is 7 month old and the backup timing is hardly 1 hour with 100watt load. I checked the acid gravity which is 1200. The Ups works fine on other batteries. Can anyone help what i need to do?

check the physical appearance of battery if the casing is swollen it has internal short circuit either 1 or more cells have depleted due to over charging.

this is very common issue when the charging does not cut-off at specific point i.e. battery reaches 13.8 volts.

Your UPS is stupid. Its the culprit. Battery got nothing to do with overcharging or low backup. Your UPS killed it. But this killing process takes time and you think ups working on another battery is ok.
My 2nd battery too is giving 6-7 hours of load after completing 3 years in march 2020. 3 hours tu paani ki motor chala jaati hei. 800 watts load pr.
Sasta ups hoga ya china wala latest model ya dhoka hua.
Another relative of mine told me this week. Yaar UPS per trip wali light on hei. I said battery ka paani check kro woh tu kam nai?! He said paani?? What paani. Men ney tu 2 saal se paani check hi nhn kiya. I said. Battery is gone. But i was amazed ke 2 saal pani check kiyay bina ABID (my electrician friend who made those UPSes) ka ups battery kay paisy wasool kr gya.
