PP35 battery 🔋 issue

In power panel PP35 , battery discharged alarm appeared despite of anew battery has been installed.
It was replaced to make sure all the configuration parameters memorised in the PLC remain in memory.
As with old battery the configuration paramrters cant be memorized when power off.

What number/alarm do you have?

Hello Mohamed,

Have you checked the charge on the battery? To validate that the battery is good measure it with a multimeter to see if the voltage reads around 3V. The 3V / 950mAh lithium batteries have a storage time of 3 years so if the battery has been in storage for a while it may no longer be good. If the charge is good, knowing the alarm number as Marcos asked above would help troubleshoot this further.
