Inspecting lithium-ion batteries regularly is crucial for maintaining their health, safety, and performance. Here’s a recommended inspection schedule:
- Monthly Check: For active lithium-ion battery systems, such as those in solar battery storage, it’s advisable to check the voltage and current monthly. This ensures that the batteries are operating within their optimal parameters and helps detect any issues early on.
- Semi-Annual Inspection: For less frequently used batteries, a semi-annual inspection is recommended. During this inspection, check for terminal corrosion and ensure the battery casing is intact.
- Storage Conditions: If batteries are stored for extended periods, check their charge level every few months. Ensure they are stored with a charge between 30% and 50% to prevent damage from self-discharge or over-charging.
- Visual Inspection: Regularly inspect batteries for signs of swelling, leakage, or excessive heat, as these can indicate failure or potential safety hazards.
- Annual Professional Check: It’s beneficial to have a professional inspect the system at least once a year to identify any underlying issues that might not be apparent through routine checks.
