@sumudu It will work for it. It's getting good results from my Feb 2011 MacBook Pro. FruitJuice has a 14-day trial app on their website, the full app is on the Mac App Store. The aim seems to be to run your Mac on battery for 20% of the time & charge when it hits 20% remaining.
You should start seeing results after the first week on the free trial app.
