Garage Heat Killing Your Gear? Florida Rules for Electronics

140-degree garages versus batteries, drives, and routers — what survives, what dies, and where to move it.

  1. 1. Know the casualties: batteries first

    Lithium batteries swell and fail fast above 110 degrees sustained — laptops, tools, and backup banks suffer first. Hard drives and capacitors age roughly twice as fast per 18 degrees above room temperature.

  2. 2. Move the vulnerable inside

    Batteries, backup drives, and rarely-used laptops belong in climate-controlled space — a closet beats any garage. Networking gear that must live there gets ventilation and shade, never sealed boxes.

  3. 3. Insulate what must stay

    For garage TVs, fridges-with-screens, and workshop PCs: shade from direct sun, raise off concrete (condensation), and add a thermometer with phone alerts. Monitoring beats discovering.

Garage Heat Killing Your Gear? Florida Rules for Electronics — When to Call a Pro

  • Swollen batteries anywhere — safe removal and disposal, promptly.
  • Garage office or workshop needing climate-proofed tech setup.
  • Heat-damaged gear assessment — what survived, what to retire.
