eli5 what is meant by battery ratings?

329 views

**Q1:** I have a battery, say 15 AH and I have a load which consumes 1.5Amps; How does this used to see the capacity of a battery? If the battery is able to deliver 15 AH of capacity that means will it die/discharged in 10 seconds if I put a 1.5 Amps load on it since load is taking 1.5 Amps from battery every second or does it mean it will die/discharged in 10 hours? Is the rating on battery tells us the discharging rate in hours or seconds?
**Another question:** What will happen if I connect the AC terminals to battery? I know it won’t charge but will it explode or something like that? Is it dangerous for us/battery to do this thing? If I have a line wire from which both AC and DC are passing through and now I connect the battery with it, will it be able to filter its DC component from wire itself (and charge itself) or do I have to make a filter(rectifier) for it to separate DC 1st and then charge the battery?
**Q3:** What will happen if I use the neutral wire to carry both the DC + AC line? Should I use a thicker wire? Will it cause some different oscillations in the wire? Is it bad for the AC line?

A 15Ah battery will provide 15 amps for an hour, 1 amp for 15 hours or 1.5 amps for 10 hours, in ideal circumstances.

AC is 110V in the US, higher in Europe / the UK. This will at the very least kill the battery, and it will probably overheat and maybe explode. You don’t want boiling battery acid in the face.

Don’t even think about it. It looks robust but this is to handle high current, not high voltage.
