Batteries’ output is measured in watts.

Can we please not post such dumb articles? Like any article mentioning battery capacity in watts

Welcome to the rabbit hole of energy storage.
Turns out nobody cares about the capacity but about the discharge rate. Which is why you’ll often hear about how many Gigawatts a certain energy storage project has, and nothing about GWh.
If you think about it for a bit, it does make sense. A lot of solutions would take days to fully discharge, so you might think “oh we have an entire city’s energy consumption for a week in some storage”, but in reality you could maybe power one neighborhood with that cuz of the discharge rate.
So, capacity refers to the “output capacity”.

Energy capacity is in kWh, discharge capacity would be in W.

Sorry! I have dyscalculia, so I’ll admit I didn’t try to analyze the numbers at all. I can delete the post

Ignore them they’re being mildly pedantic

How can an article reliable convey information when the core measurement unit used in article is invalid? Not taking about slightly wrong numbers, but the foundation of the article.

Storage does have 2 relevant metrics. how fast it can charge/discharge in GW, and the amount of energy available in gwh. Batteries typically have both these amounts equal. While other storage technologies usually can discharge a large amount of gwh at a slow rate. The discharge rate is often limited to the line capacity available as well.

No worries, no need to remove it, it’s just articles that doesn’t make sense.
