Frequently Asked Questions
Everything you need to know about powering your devices.
Are your 18650 batteries genuine and tested?
Yes, we source all cells directly from reputable manufacturers like LG, Samsung, and Sony. Every batch undergoes rigorous capacity and internal resistance testing to ensure authenticity and performance.
How long does shipping take for lithium-ion batteries?
Due to safety regulations, lithium batteries must be shipped via ground transportation. Standard shipping typically takes 3-7 business days within the continental United States.
What is the difference between protected and unprotected cells?
Protected cells feature an integrated circuit (BMS) that prevents overcharging and over-discharging. Unprotected cells lack this circuit and should only be used in devices with built-in protection or by experienced users.
Do you offer bulk or wholesale discounts?
Absolutely. We offer tiered pricing for bulk orders starting at 50 units. Please contact our sales team for a custom quote on larger industrial quantities.
What is your return policy for electronics?
We offer a 30-day return window for unused batteries in their original packaging. For safety reasons, batteries that have been spot-welded or show signs of installation cannot be returned.
How should I store my 18650 batteries safely?
Batteries should be stored in a cool, dry place inside a non-conductive plastic case. Never carry loose batteries in your pocket or bag where they can contact metal objects and short circuit.
