    1. How long does a 3.7 V lithium battery last?

    • The typical estimated life of a Lithium-Ion battery is about 600 charge cycles. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.

    2. How do I keep my lithium-ion battery safe?

    • Below are some of the methods used to keep a Li-ion battery safe:
    • Charge or discharge the battery to approximately 50% of capacity before storage.
    • Charge the battery to approximately 50% of capacity at least once every six months.
    • Remove the battery and store it separately from the product.
    • Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).

    3. What is the difference between a lithium battery and a lithium-ion battery?

    • Lithium batteries feature primary cell construction. This means that they are single-use—or non-rechargeable. Ion batteries, on the other hand, feature secondary cell construction. This means that they can be recharged and used over and over again.

    4. Do lithium batteries lose charge when not in use?

    • The battery will drain the charge even when not in use, no matter what type of battery it is or what material the battery is made of. Similarly, Lithium-Ion batteries will drain when not in use. When you charge a completely discharged battery, you reduce its capacity.

    5. Why is the lithium-ion battery the best?

    • Compared with traditional battery technology, lithium-ion batteries charge faster, last longer, and have a higher power density for more battery life in a lighter package. When you know a little about how they work, they can work that much better for you.
