How long does the batteries that come with it last between charges?

This depends on what you're using it in. I have one in my Lenovo active pen 2. I charged it once when it arrived almost two months ago and it has yet to finish draining. I use the pen most weekdays for 3-5 hours as I do stuff on zoom. These are nimh batteries (1.2v) so they won't work perfectly in all things that take 1.5v alkaline. And nimh usually have a capacity rating of 50-75% of their alkaline counterparts. So if you were to use it in a flashlight for example, I would expect half the runtime of disposable batteries with a bit less brightness. For most uses, the fact they're rechargable makes up for the capacity.

How do you tell if it's charged? Mine didn't have the indicator light as described.

Mine has a small LED indicator light on top.

This is listed as Prime, so why does it take 5 days to arrive for a Prime member?

Haha, you'll find this as "funny" as I did when Amazon customer service had to explain it to me (for a different product). Prime guarantees "2 day shipping." That does NOT mean it gets shipped immediately. Any 3rd party seller can take however much time they need as long as the method they ship it by is "2 day" delivery. So order it today and one month from now the seller can ship it with overnight and still fulfill "prime" shipping. What a joke right?

Can the usb charger also be used for aaa and aa size nimh batteries? thanks.

You can recharge AAA or AAAA rechargeable batteries with this USB charger.
