MP2731 Battery not connected detection

Hi,

Part: MP2731

Is there any way to detect if the battery is not connected by reading any of the status registers?

Hello hcglitte,

There is no status register for checking battery connection. You could try checking if there is a battery voltage seen on REG0EH.

Thank you,

Thanks.
I think I tried this via GUI. The problem was that the charger tried to initiate charging, and while doing this the voltage read from this register was not 0, but fluctuating - if my memory serves me right. By doing several reads of the register, perhaps it is possible to deduct that the battery is not present - i.e. because of non stable voltage level etc.

Is buying a refurbished battery worth it or not?
