Symmetra LX - Internal battery temperature threshold violation

[Anonymous user]

Internal battery temperature threshold violation message from Symmetra LX. Started having batteries overheat for no reason.Some swollen and very hard to remove. Room temp is 65, all 5 chassis are normal temperatures, internal test pass on UPS, however we have had 7 batteries go down today. Any advice

How old are the batteries (serial numbers would tell us)? Did you have any power outages recently? When you say the internal self-test passed, when did/does that occur?

Typically for swollen batteries in an LX, disengaging the module either by pulling it out of the frame a few inches or turning the black knob on the front to the "off" position and allowing them to cool (maybe point a fan at them, too) will cause the swelling to go down enough to fully remove the battery.

You mention 7 batteries so you must have an extended run frame. What is the frame model number?
