AOA, bro i have a problem with my ups backup, as i brought a local made ups and AGS 95A 2 batteries, as the ups requires 24V, almost 3 years aprox, so all these years i pored in tap water sometimes distilled,and the battery contained the electrolyte at the time of purchase, my load on ups is 3 fans, 2,3 savers , all these years it went fine but this summer the backup decreased to 50mins so i started to mantain water level at max on batteries, so as time passes i was curious the backup went to 45mins, i didnt had much knowledge about ups and batteries so one day i came to this fourm and thought to flush electrolyte and i flushed it and took it to nearest battery shop for new electrolyte, everything went fine now say what backup reduced to 20mins, bro i want to ask what to do now ? , i searched on internet they say epsom salt / magnesium sulphate can bring back backup is it really true?
i called a lab chem provider today they had magnesuim sulphate but the price was 2200rs per/kg.
i dont have a hydrometer from where i can buy this in islamabad? and dont have a ampere meter and voltmeter btw i will ask about use of volt/ampere meter in future.
i opened up ups and mingled with battery charging cutoff rate, as i increase it the ups charges battery continously and the water in batteries started to boil but the backup increases max 10 mins.
any idea of shop who sells original AGS battery in isb?
