How to lower the cost

  • Charge vehicles and batteries overnight if your utility offers time-of-use rates.
  • Standby draw hides in garages — openers, chargers, and old fridges add up around the clock.
  • Electric yard tools cost pennies per session; the battery’s lifespan is the real economics.
