  • Stone Cold Dead? This could be a simple connection issue, a dead cell, or a full-on battery meltdown (hopefully not the last one!).
  • Flashing Red and Green Like a Disco Ball Gone Rogue? This often indicates a low voltage cell that needs a jump start (more on that later).

Step 2: The Charging Ceremony (sans Incantation)

  • Double-check the charger. Is it plugged in properly? Is it functioning (maybe try it with another battery)?
  • Cleanliness is next to battery-ness. Give the battery contacts a good wipe with a dry cloth. Sometimes, a little dust is all it takes to kill the party.
  • The Power of the Pause. Sometimes, a stubborn battery just needs a time out. Leave it out of the charger for a bit, then pop it back in and see if it wakes up.
