So the other day when blackout happened the ups throw me this error :
UPS: The battery power is too low to support the load; if power fails, the UPS will be shut down immediately.
And it wont sustain the load, which is strange cause the load isn't even 10% on the readings
So i replace the battery, i tested all of them with before installing to make sure it's brand new.
but the same error happens again after i run the calibration (after the battery is 100%)
Any ideas?
