Tips to maintain the Jackery battery charger for longer use:

Go through at least one charge cycle per month

Keeping the electrons in the battery moving occasionally is important to the proper maintenance of a lithium-based battery. Going through at least one charge cycle per month will help better maintain the battery life, i.e. when there is one LED light blinking, it’s time to recharge the Jackery. We highly recommend you to recharge the Jackery at least once a month.

Avoid excess heat

Lithium-ion suffers from stress when exposed to heat. Try to keep your Jackery at room temperature, between 20 and 25°C (68 - 77°F). It shortens the lifespan of the battery if exposing a fully charged Jackery to elevated temperatures.

Allow partial discharge

Lithium-ion batteries do not have memory so the battery does not need periodic full discharge cycles to prolong life. The depth of discharge (DoD) determines the cycle count. Allow partial discharge and void full discharges. It’s better charge the Jackery more often between uses.

Store discharged batteries

If you plan to store a Jackery for future use, it’s recommended to store 40% discharged battery in a refrigerator (not freezer). Always remember to recharge it as if it ever drops down to zero charge, it can never be recharged again.
