I have a Symmetra LX 16KVa and it has 4 battery module. 3 out of 4 modules have Long brand (12V 9AH) but the other one has CSB brand (12V 7Ah).

Does the UPS recognize that there is different brand installed in the system and does it affect my runtime?

Yes, it is SYBT5. What will happen on the unit if I didn’t change the 7ah to 9ah? What are the pros and cons of these different batteries?
