The mechanic said he needed a battery, I thought of getting a used one but then I thought it would die out soon and then I'll have to get another one and spend money again.
So I just thought of buying a new one, it would cost more of course but then it'll last a much much longer period. After thinking I just went to get a new one. It costed me 4,200rs it's an Exide (wet, 12V 70 AMP) with a 6-month warranty.
@reezvaan, thanks for the advice 
P.S: I love how the guy wrote 'Fooxy' on the receipt instead of mister so and so
