T480 Dual battery help!

2019-05-18, 22:26 PM

Currently have set up to charge both my battery until 85% but only 1 have managed to charge to 85% while the other is no where close to 85%. Any ideas why is it doing this?

Hi Dexter01!


Welcome to the Community,


Try setting the Charge Percentage under Stop Charging at Tab to 100%, and check for any changes. Also, in the same window in Lenovo Vantage, check if the Conservation Mode is Enabled. Try disabling Custom Battery Charger Threshold as well, and check if both will charge up to 100%. Let us know how it goes.

With you setting, battery 2 will only begin to charge when it drops below 40%, and continue until 85%. Since 58% is well above 40% so the laptop does not take charging action on connecting the power adapter. If you want it to always fill up to 85%, set the threshold 5% lower (i.e. 80%) or click that Auto checkbox below.
