Can a failing battery cause poor compression numbers?

So from what I've seen my fried battery caused a million problems. Replacing that battery was like transforming the car.

The battery kept dying on me while I was compression testing a couple months ago, causing the engine to spin at lower rpms. So my question is, would this have caused me to get low numbers?

Yes, it states your bettery needs to be fully charged and you can even keep it on charge while doing the test

Yeah, I imagine it could. A good battery can really improve the health of an engine

Looks like I'm retesting soon.

I was already happy with the old numbers, maybe I can be jaw-dropped this time.

Yeah, definitely. Battery charge/life will definitely affect a compression test. Make sure it's good and charged.

Yea I had a 9 year old battery last time. Now I have a new battery so hopefully it will be much better.

Yep. I got 190's across the board this time. Last time I got 160's. I think this was partly also due to not opening the throttle last time. But I'm super happy now!
