I have Lenovo G580 (2689) for last 6 months. Its battery lasts for more than 3 hours. Battery capacity is 43200 mWh. I want to know what capacity is expected in a new battery? I didnt see it when i bought. only recently i have come across all this. So what capacity should i have when i purchased my laptop. Is current capacity ok or needs some repair?

The Lenovo G580 (2689) uses a Lithium Ion 6-cell, 48Wh battery as per this pdf data sheet. Since 6months have passed, your current 43200mWh battery capacity is still ok since battery do degrade overtime due to usage, aging, and heat.
If the battery last an hour or less on full charge then you may need to contact lenovo for a replacement battery.
Hope this helps.
