Long-life lithium batteries are marketed as batteries with extended life. They utilize more advanced lithium chemistries like lithium-iron-phosphate (LiFePO4) known for their stable nature, as well as high charge-discharge cycles. Better designed battery management systems that monitor and control volts, current, or even temperature are also incorporated. By eliminating overcharge, deep discharge, and thermal issues, these batteries can withstand performance barriers for extended periods, effectively reducing the need for frequent replacements and achieving long-term energy storage solutions.
