What’s in the 18650 Battery Range at Battery Mate?

Not all 18650s are the same. Here’s what you’ll find in our collection:

Protected Vs. Unprotected

Protected batteries include a safety circuit to prevent overcharging and short-circuits. Unprotected versions offer slightly more capacity but need more care in use.

Flat Top Vs. Button Top

The shape of the terminal matters, check what fits your device before buying.

Different Capacities And Discharge Rates

Higher mAh means longer run time. If you’re powering something high-drain, like a torch or tool, go for higher discharge ratings.

Need batteries for your vacuum? We’ve got Dyson batteries that match original performance with better value.

Choosing the Right 18650 Battery

Not sure which one you need? Here’s a quick checklist:

Check Compatibility

Some devices only work with button-top or protected cells, check your manual or old battery.

Consider Your Power Needs

More mAh = longer use between charges. Pick what fits your needs.

Match Discharge Rate To The Task

High-drain devices need batteries that can deliver consistent output.

Safety Features

If your gear doesn’t have built-in safeguards, stick with protected batteries.

FAQs

Do all 18650 batteries have a rechargeable capacity?

Yes. A genuine 18650 rechargeable battery always consists of lithium-ion and is rechargeable. If it is not, it is not the real thing.

How do protected and unprotected 18650s differ from each other?

The circuit inside protected cells is designed for safety. Unprotected ones do not and tend to be much better for products that already have internal protection.

Can I use 18650 batteries in my flashlight or vape?

Many torches and vapes use 18650s, but it depends on the size, voltage, and whether your device needs a protected cell. Always double-check.

How long do they last?

You’ll typically get 300 to 500 full charges. That’s two to three years, depending on use.

Do I need a special charger for 18650s?

Yes. Use a charger designed for lithium-ion 18650 cells to avoid damaging the battery.
