Hardware Battery replacement

[ganons]

So I have a v1 switch with atmosphere and the battery doesn't seem to hold up anymore. Charged 100% overnight then checked at day time it was 50%. Auto RCM enabled.

What's a good battery brand to buy (UK based).

Don't skimp pn it.
Just get a original replacement.

I doubt knockoffs hold water.

Maybe the "doesn't hold out anymore" is due to thermal issues ?
Dirty fan etc ?
