Shopping for a replacement 18650 battery in Canada, or a charger that actually protects your cells? You are in the right place. Everything below ships fast and discreetly nationwide.
18650 Batteries
The 18650 is the most common high-drain battery in vaping, used in countless box mods and single-cell devices. A quality 18650 battery delivers steady power, good battery life and a safe, consistent vape. We stock genuine 18650 cells in Canada from trusted brands, so you avoid the rewrapped and counterfeit cells that flood the market. Always check the wrap is intact before use and replace any battery with torn or damaged insulation.
21700 Batteries
Newer high-output mods often take the larger 21700 battery, which holds more capacity than an 18650 for longer sessions between charges. If your device is built for 21700 cells, use them rather than an 18650 in an adapter for the best performance and safety.
Vape Chargers and Cables
A dedicated external charger is the safest way to charge removable batteries. Our vape charger range includes single and multi-bay chargers that monitor and stop charging at the right voltage, which protects your cells and extends their life. We also carry USB-C and micro-USB charging cables for built-in-battery devices.
Battery Safety in Canada
Vape batteries are safe when treated with respect, and risky when they are not. A few rules keep you protected.
Never carry loose batteries in a pocket with keys or coins, as this can cause a short. Use a plastic battery case.
Always check the wrap and insulator ring. If either is torn, re-wrap the cell or retire it.
Use married pairs. In dual-battery mods, keep the same two cells together, matched by brand, age and charge level.
Charge on a proper charger, not an unknown wall plug, and do not leave batteries charging unattended overnight.
Buy genuine. Counterfeit cells overstate their ratings and are a leading cause of battery failure.
Which Battery Does My Vape Use?
Check your device or its manual for the cell size, usually printed as 18650 or 21700. Single-battery mods are often 18650, while larger, higher-wattage mods use 21700. Pod systems and many starter kits have a built-in battery you charge by cable instead. If you are unsure, message us your device name and we will confirm the correct battery and charger before you buy.

Frequently Asked Questions
What is an 18650 battery?
An 18650 is a rechargeable lithium-ion battery measuring 18mm by 65mm, the most common removable cell in vape mods. A good 18650 battery delivers high, steady current for a safe and consistent vape. Always use genuine cells and a proper charger.
Which battery does my vape take, 18650 or 21700?
Check the size printed on your old battery or in your device manual. Single-cell mods are frequently 18650, while many newer high-output mods use the larger 21700. If your device has a built-in battery, you charge it by cable and do not swap cells. Ask us if you are unsure.
What is the difference between 18650 and 21700 batteries?
The numbers are the dimensions. A 21700 is physically larger than an 18650 and usually holds more capacity, so it runs longer between charges and can deliver more power. Use whichever size your device is designed for, and do not force the wrong cell.
How do I charge vape batteries safely?
Use a dedicated external charger for removable cells, or the supplied USB-C cable for built-in batteries. Do not leave batteries charging unattended, avoid cheap unbranded chargers, and stop using any cell that gets hot, swells or has a damaged wrap.
Are 18650 vape batteries safe?
Yes, when you buy genuine cells, keep the wraps intact, use married pairs in dual-battery mods, and charge them properly. Most battery incidents come from counterfeit cells, damaged wraps or loose batteries shorting in a pocket. Follow the safety rules above and you are protected.
Do you ship vape batteries across Canada?
Yes. We ship batteries, chargers and cables across Canada with fast, discreet delivery. You must be 19 or older to order, as every purchase is age-verified. Free shipping is available on qualifying orders over $150.
