Hi,
I have a question about battery replacement on a UPS system,
I currently have 4 battery sets of 48 batteries each (total 192 batteries),
I understand one battery set doesn't provide enough power, and it seems like the battery set have at least 1 battery (from 48 batteries) which is faulty, and this impact the entire battery set,
I received recommendation to replace all the batteries in the battery set, instead of trying to identify the faulty battery and replacing it (assuming there is only 1 faulty battery),
Can you advise if I should really replace all 48 batteries? and not trying to replace only the faulty one?
what will exactly happen if I will try to replace only the faulty battery and keep the rest of the batteries which are not faulty?
Thank you in advance for your help!
