My battery doesn't last for very long

본문:

I hope someone can help me. My battery was draining very quickly so I bought  a new one from this website.

However, the battery still drains really quickly. Even though the 'battery time remaining' in the information when I click at the top might say 2 or 3 hours, it will never last longer than about an hour.

Even if it is on 100% and I shut the lid, by the time I get back to the laptop a few hours later it will have lost a significant amount of battery despite not being used.

I've tried to reset the PRAM and recalibrate the battery but it doesn't seem to have done the job.

Any suggestions would be most grateful.
