How long will my battery last?

Our batteries are expected to last approximately 300charge/discharge cycles. That means you can charge to 100% capacity and let it die at 0%, about 300 times. How long it /asts depends on how frequently you're using the battery.

All Zonli battery-heated products offers three heat settings– low, medium, and high – with varying heating times depending on the level you choose.


What can I do to extend the life of my battery?

It's important to fully charge and discharge your battery every 3-6 months. This entails charging it to full capacity, connecting it to your balnket, and using it until it runs out of power. Afterward, fully charge the battery and store it in a dry, cool place. This practice helps prolong the battery's lifespan, as extended periods of non-use can be detrimental to lithium batteries. We suggest doing this maintenance routine during the summer when you're less likely to rely on the battery for warmth.

Can I plug a different battery into my Zonli product?

The Zonli Portable Heated product is compatible with other batteries featuring both USB and DC interfaces. However, we cannot guarantee the heating time. Lithium batteries come in different capacities, and if the battery charge surpasses the blanket's capacity, it might not function optimally.


Can I bring my Lithium batteries on an airplane?

Our batteries are safe for travel on an airplane. However, due to FAA regulations, you must pack your battery in your carry-on baggage.


How do I dispose of my batteries?

It's crucial not to dispose of lithium batteries in the trash due to safety and environmental concerns. Instead, they should be recycled. You can visit to find a recycling drop-off location in your area specifically for lithium batteries.
