The battery life of 'Acer' is good but their sale in the market has come down I don't know why. HCL was good too but they have stopped producing laptops. You can try 'Dell' or 'Lenovo'.

I'm using Acer laptop and the battery life is good, I think bell or HP is good too

Expensive laptop or cheap laptop I think batteries are lasted the same. I am using Lenovo and it takes more than 4 hours.

Mine is lasting more or less 2 hours only, so I removed the battery instead for emergency purposes and just plug it whenever I use it.
