How Can You Maintain Your External Battery for Optimal Performance?

To maintain your external battery for optimal performance, follow these key practices: charge your battery regularly, avoid extreme temperatures, and store it properly when not in use.

Charging regularly: It is essential to keep your external battery charged between 20% and 80% for optimal longevity. A study by Battery University (2010) indicates that lithium-ion batteries, commonly used in external batteries, perform best when not fully drained or constantly kept at 100%. Regular charging helps balance the battery’s cycles and can extend its lifespan.

Avoiding extreme temperatures: External batteries should be kept away from high heat and extreme cold. Research from the Massachusetts Institute of Technology (MIT) highlights that temperatures above 30°C (86°F) can cause irreversible damage to lithium-ion batteries. Likewise, storing a battery in freezing temperatures can lead to loss of capacity. It is best to operate and store your external battery at room temperature, ideally between 20°C and 25°C (68°F to 77°F).

Proper storage: When not in use for an extended period, it’s advisable to store the external battery partially charged, around 50%. The National Renewable Energy Laboratory (NREL, 2019) suggests this helps prevent deep discharge, which can degrade battery health. Additionally, keep the battery in a dry, cool place, away from direct sunlight and moisture, to minimize the risk of damage.

By following these practices, you can ensure your external battery remains in good condition and performs well over time.
