Amar ekta 600va ups ase jetar battery was 12v9ah ,jeta purai gese, so i bought a new one from gulistan. After seeing the previous roasted battery, shopper told that, as it got swelled , the main guity is the charging system of that ups, and the new one will also get roasted within 2 to 3 months...so better check the ups by them or any other shop. My question,
1. Shall i get the ups checked? If u know any other good place to check it, help me here....
2. Is there any problem, if i connect two batteries instead of 1 ,by parallel connection?
