What you Should Know When use Process of Lithium Battery Pack

Avoiding physical damage

Protects lithium battery packs from impact, compression, or other physical damage. If the casing is damaged, deformed, or leaking, please stop using it and seek professional repair or replacement.

Correct storage method

If the lithium battery pack is not used temporarily, it is recommended to store it in a dry, ventilated, and dark environment to ensure that the battery pack is at an appropriate charge (generally between 30% and 50%). When it is not used for a long time, it should be checked regularly to keep the battery normal.

Avoid short circuit

Short circuits are key to battery pack safety. Once a short circuit occurs, the energy inside the battery pack will be quickly released. When using lithium battery packs, be sure to avoid short circuiting the battery and avoid direct contact with metal objects or conductive media that may damage the battery pack.

Prevent overheating

When using lithium battery packs, avoid long-term exposure to high temperature environments, and it is strictly forbidden to allow water to enter the lithium battery pack. If the lithium battery pack is found to be abnormally hot, stop using it immediately and place it in a ventilated place to cool down.

FAQ

Q: How long do lithium battery packs last?

A: Lithium battery packs typically have a lifespan of around 2-3 years or 300-500 charge cycles, whichever comes first. Proper maintenance and care can help extend the lifespan of lithium battery packs.

Q: Are lithium battery packs safe?

A: Lithium battery packs are generally safe and unlikely to fail, but only if the cells are not defective and not damaged. When a lithium battery pack fails to operate safely or becomes damaged, it may create a fire and/or explosion hazard.

Q: What shortens the life of lithium battery pack?

A: Dropping or puncturing the battery pack can cause damage to the cells and reduce their lifespan. Over time, the performance and capacity of the battery pack will naturally degrade, eventually rendering it unusable.

Q: What is the difference between lithium battery and lithium battery pack?

A: A lithium battery is a single battery cell that contains lithium ions, while a lithium battery pack is a collection of multiple lithium battery cells that have been connected together to increase the total voltage and capacity of the battery. The pack may also contain additional circuitry for protection, monitoring, and balancing the cells.

Q: How to store lithium battery pack?

A: Store the battery in a cool, dry place. Lithium batteries should be kept at room temperature, below 30°C (86°F), and away from direct sunlight, heat, and moisture.
