Is it safe to store batteries in a hot car glovebox? (Battery storage for rideshare drivers on scorching midsummer afternoons)

Short answer

Context

Rideshare drivers often need backup batteries for their devices and may keep spares in the car, but worry about the risks from extreme heat inside a parked vehicle.

When it might be safe

There are no commonly accepted situations where this is considered safe.

When it is not safe

• Extreme temps inside glovebox can exceed battery safety ratings
• Swelling or leaking may occur, especially with lithium-ion batteries
• Sudden device failure possible when using overheated batteries

Possible risks

• Fire hazard if batteries overheat and vent
• Chemical leakage damaging vehicle interiors
• Reduced battery life and performance for spares repeatedly exposed to heat

Safer alternatives

• Store batteries in a temperature-resistant case and take them with you
• Keep spares in a cooler bag with an ice pack (never touching the battery directly)
• Consider power banks rated for higher temperatures

Bottom line

Storing batteries in a car glovebox under direct sunlight during midsummer can lead to safety and performance issues. Seek shaded, cool alternatives to protect your devices and vehicle.
