Hi!
I have a pcb that is being powered by mains and backed-up by a 12V SLA rechargeable battery.
Due to charge and discharge cycles, the SLA battery might lose its properties.
So I would like to if there are any methods to check if the battery needs to be replaced or not.
I have an ADC so I can read SLA battery voltage and do some calculations.
I guess there is a method of applying a constant load, pulling a certain amount of current from the battery and by reading its voltage it might be possible to determine whether the battery is ok or needs to be replaced.
Is anyone aware of such methods?
Any papers about this and the theory behind it?
