These are for TV remotes, smoke alarms etc .. Are the blue lithiums ie $22 9V battery recommended?  The silver lithiums are $12 and there are other alkalines.

Use standard batteries and replace them regularly.
High-end batteries are wasted for these uses.

Lithium 9 volt in a regular smoke detector is a waste in more ways than one. Alkaline batteries are as well. Use the cheap lead cell batteries. They take longer to completely discharge at the end of their lives, which means you will have a longer time with the smoke detector warning you about low battery than you will with alkaline or a lithium battery.

For wireless smoke detectors (that communicate with each other), use Alkaline or the type of battery that the smoke detector was delivered with.

For remote controls, use cheap alkaline batteries.
