I would like to buy a battery for invertor. I would like to have a cheapest one in chennai. I can not invest 10k as of now in invertor. at the same time i would like to have it in working condition before the rainy season starts.

Or I would like to know some one who can help me to get a new invertor on EMI basis. may be in 5 or 6 installments would be fine and give me some confrt level to manage my other house held expenses.

Thank you
