Electrical – CV or CC battery charging via SMPS module


I am using attached SMPS module, it has battery back up UPS function. I read the datasheet and I couldn't find information what type of battery charge scheme I need to use.

  1. Should I use constant voltage charge battery?
  2. Should I use constant current charge battery?

You don't have to care about the battery charge scheme, because charging is managed by the SMPS.

You just need to know the type of battery supported by this SMPS. It is not clearly indicated in the datasheet, but I'd bet for Sealed Lead-Acid batteries. They are 12V (as specified in the datasheet) and typically used for UPS systems.
