💡 Care, Storage, & Tech Tips

Yes — perfectly safe today. Modern polypropylene cases prevent the old self‑discharge issues.

No. Bad idea! Total myth! Store them at room temperature. Refrigeration causes condensation and corrosion. It also discharges (drains) the battery.

  • Clean it: Wipe with baking soda + water to neutralize acid residue.
  • Charge it: Fully charge before storage. A charged battery won’t freeze until −75°F; a discharged one can freeze at 15°F.
  • Disconnect it: Remove the negative cable to prevent parasitic drain.

💳 Ordering & Warranty

Yes! We offer tier‑based commercial accounts and wholesale pricing for fleets, government, contractors, and local businesses. Contact our store directly to set up an account.

Warranty varies by brand and type. Premium automotive batteries typically include a 2–3 year free replacement warranty, while specialty or power sports batteries may have shorter terms. Always keep your receipt or ask our staff to link the purchase to your customer profile for easy warranty tracking.
