If electricity is so fast, how it doesn’t immediately charge up capacitors and batteries?

I’m pretty aware that this is a “dumb” question, but my basic understanding of electricity can’t figure it out. I know the basic concept of resistance, currency and voltage, but I can’t comprehend how it takes so long to store charge in a battery

This is not literally how it works obv but just as an analogy, think of electricity running through a wire as a hose. A battery is a water tank in the air. Takes a bit for the hose to fill up the bucket and depends also on the velocity/thickness of the hose (volt/amperage). The speed of the water (volt) times the width of the hose (amp) gives the total water moved (wattage). Bigger bucket (battery) takes longer to fill and more water (wattage) is faster to fill.

Once the water is suspended, you can poke a hole in the tank and the stored “potential energy” is released. Of course this is a chemical process and electricity is a field and all that but just as a way to conceptualize.
