Question dell 7400 2 in 1 52wh battery

[rosycreates]

Hi,

I would really like to buy a (new to me) Latitude 7400 2 in 1 with a 78wh battery for the long lasting battery. However, I can only find them with 52wh (so far). About how long does the 52wh battery last?

TIA!

No real way to tell, depends on usage and how worn the battery is. New battery with decent usage, I would expect 3 hours give or take. You can change that with lowering screen brightness and setting limits to cpu speed.
