Choosing a battery by watt-hour (Wh)

[JohnLM]

I've been working on an updated run-time calculator and get different results, and I believe that I need to factor in the Wh also. But that may be for another story/topic.

Anyway. I've seen battery watt-hours (Wh), (like 268, 360, 400, 517, 700 Wh's) with build-in 600-watt inverters.

Using the above Wh list, which battery would you choose and why?

Wh is a measure of total stored energy.

I would choose the one with the most favorable $/Wh ratio.

Is low temp a consideration?
is discharge rate a consideration?

The suspense is killin’ me, please link the batteries with built in inverters

I believe they are referring to portable solar generators.
They are usually rated in wh.

We THINK you are asking about solar generator/power bank units.

Please post what you are teying to accomplish.

Correct.., portable solar generators. I was browsing around Amazon, looking at the many portables they have, and reading the specs.

On some of the listings, I was getting confused with the runtimes posted for various common items such as lights, cellphones, laptops, etc.., and they appeared to be the same runtime for the higher Wh units. I thought they should be higher.
