Frequently asked questions
Is a 26650 battery the same as an 18650?
No. A 26650 battery is substantially wider than an 18650. Do not substitute one for the other unless your device manufacturer explicitly supports the alternate size and any required sleeve.
Is the XTAR 26650 7000mAh battery protected?
Yes. XTAR specifies a built-in protection circuit and a big button-top positive terminal for this model.
What charger should I use?
Use a lithium-ion charger that supports 26650 batteries and follow the charger and battery instructions. Store and carry spare cells in a protective battery case, away from loose metal objects. Do not use a cell with a damaged wrap or other signs of damage.
