The Battery Charging Association emphasizes using chargers that meet industry standards for lithium technologies to ensure safety and efficiency.
-
Follow Manufacturer Guidelines: Following manufacturer guidelines involves adhering to the specific recommendations provided in the battery’s manual. This includes optimal usage practices, maintenance routines, and specific charging parameters. According to a 2019 article published by the Institute of Electrical and Electronics Engineers, following these guidelines can markedly prolong battery life.
-
Store Properly During Long Periods of Inactivity: Storing properly during long periods of inactivity means placing the battery in a safe, climate-controlled environment when it is not in use. Keeping the charge at around 50% when storing can prevent degradation. This recommendation is backed by a 2021 study published by the Journal of Energy Storage, which indicated that proper storage conditions significantly improve the battery’s shelf life.
Implementing these practices will help ensure that a 5kW lithium battery remains efficient and has a prolonged lifespan.
