Frequently Asked Questions (FAQ)

Do I need an external battery charger to charge the LTH35?

No! One of the best features of the SPERAS LTH35 Rechargeable Li-ion Battery is its built-in USB-C port. You can plug a standard Type-C cable directly into the side of the battery to charge it, making it perfect for travel and camping.

Why is the -40°C cold resistance important?

Standard lithium-ion batteries lose a massive amount of their capacity and discharge capability when temperatures drop below freezing, often dying completely. The SPERAS LTH35 is engineered with specialized chemistry to maintain stable voltage down to -40°C, ensuring your flashlight works when you need it most in winter conditions.

Can I use this 18650 battery in non-SPERAS flashlights?

Yes. As long as your device accepts standard "button-top" 18650 batteries and supports a 69.4mm length (which accounts for the built-in protection and USB-C circuitry), the SPERAS LTH35 will provide exceptional high-drain performance.
