I have a Dell UPS 500W that I need to replace the batteries. The online store has batteries for 3 different models but I can't find the model on the UPS any where. How do I find which batteries to order? The have model options for CH38X, H900N and J715N.
I can't find a serial # or model # on this thing. Where are these located?
Is there a UPS support forum, couldn't find that either so hopefully this is the best place for this question.
