Caught a sneaky issue with backup battery installations

I was putting in a new backup battery for a comms system and almost missed a key step. The polarity markings on SOME units are SUPER faint and easy to overlook. Connecting it wrong could fry the entire avionics suite. Double-check those labels with a magnifying glass if you have to.

Nearly reversed the wires on my home server once, same panic when the LEDs didn't light.

Hey, reversing LED wires usually just stops them lighting, no real damage.

From my own mess-ups, reversing LEDs rarely causes harm! They're built to handle reverse polarity without frying the circuit. Just flip them back and you're good to go!
