What is this 9v battery mAh or Ampere-hour?

Unknown as it's not listed on the battery!

Where do i find the expiration date on these batteries i just purchased? can't find it on the packaging. buyers should know expire date, right?

The expiration date is on the bottom on the casing. Mine show 09/24' If you have trouble try a magnifying glass!

How long will they last in device that’s seldom used?

I don’t know but I haven’t had a problem with them. For the money they are a good deal. My daughter has used these type battery’s for years.

Do these charge with nicd or nimh charger please?

These batteries are NOT chargeable , these are Alkaline Batteries that last for years and when they die they are dead and you must replace them. No Alkaline batteries I have ever heard of are rechargeable.
