Trackpad cursor moving around on its own and clicking anywhere

Hello.

I own a Macbook Pro Late 2011 model and recently the trackpads cursor is behaving weirdly, like it moves around on its own, it clicks anywhere.

I am guessing I need to change my trackpad ?

MacBook Pro 13" Unibody (Mid 2009-Mid 2012) Trackpad

Will the trackpad on above link help me ? Do I need to check model number A1278 ?

or just 'Mid-2009--Mid-2012' is good enough to assume it will work with my laptop.

Thank you

even the vertical page scrolling sometimes does not work

the cursor erratic behavior seems to have stopped today but the 2 finger scrolling is not smooth, sometimes I can not scroll.

and then it works smoothly.

Using the coconutbattery app I found out that MBP battery had 1643 cycle count.

Sounds like you have two problems here! A battery which also needs to be replaced. As you can see here you've exceeded its lifespan! Determine battery cycle count for Mac notebooks

Before buying a new trackpad I'd open the Mac and make sure the battery is not swollen. A defective battery might push on trackpad and cause the symptoms you're experiencing.

I checked with a vendor. The battery does not seem to be swollen.

Can't we figure out if the battery is swollen without opening the mac ?

No, not possible, it needs visual inspection. You just need a small philips screwdriver to open the bottom, your fingers to unplug the battery connector, and a tri-winged screwdriver to remove the two battery screws. It just takes 10mins to do all.
