7. Maintenance
7.1. Long-Term Storage
It is recommended to charge the battery to 50% every 3 months if it is to be left unused for a long time. This helps maintain battery health and extends its lifespan.
7.2. Anti-Swelling Fixture
The battery incorporates an anti-swelling fixture inside. This fixture provides a stable, inward force that prevents the cells from expanding due to overcharging, aging, or high temperatures, thus greatly improving the battery's performance and longevity.
