A1286 late 2011 weird lag?

I have this a1286 that had the graphics issue, I installed a Tiresias and all works great,

Problem is after a couple of reboots or just randomly when turning it on the machine runs really really slow with like a crazy lag on the trackpad curser and it taking an age to respond to any kind of app.

Things ive tried,

New HDD
different ram
different trackpad

installed OS catalina and os high siera and it does the same thing still, the only way I can get it back to normal is by restting the SMC then it will fine again for a short time before stating again after a reboot.

Any ideas?

well bugger me!

It was a (New) Battery causing the problem,brand new only 2 cycles,, I swapped this bat with one from a working machine and the problem jumped from this mac to the perfectly good one I swapped batteries with!

Ive never seen this before, is it a faulty battery should I return it?

Thanks dude

I saw too many weird issues caused by fake batteries.
One time, I got an 820-3332 with graphics glitches and artifacts; just because of f**g new chinese battery.
