Replacement battery for Samsung notebook

[sling-shot]

I have just discovered that my barely out of warranty Samsung NP305 notebook/netbook battery is malfunctioning and needs to be replaced for safety purpose.

I expect the OEM replacement to be 4K+ in cost.

Is there any reputed cheaper compatible battery? I would love if it is of higher capacity too.

Just came to know that OEM battery is 5,600/=. Good GOD! And I have no success finding a cheaper replacement.
