LiFePO4 Battery Life: How Long Do They Really

Most lithium-iron phosphate batteries are rated for 2,000 to 5,000 charge cycles. That kind of cycle life makes a big difference for anyone relying on consistent, long-term energy storage—whether it's in an RV, solar setup, boat, or home backup system.
One of the biggest reasons people switch to lithium iron phosphate batteries (LiFePO4) is battery life. While lead acid batteries and AGM options often need replacing every 3 to 5 years, quality LiFePO4 batteries can last up to 10 years or more with proper use and storage.
A Bit of Upkeep Goes a Long Way: Store them properly, check in on them occasionally, and you'll get years of steady performance—whether for solar, RV, marine, or backup use. Ionic deep cycle batteries routinely last 10+ years. What is a LiFePO4 Battery? A LiFePO4 battery is a rechargeable battery made with lithium iron phosphate.
A LiFePO4 deep cycle battery is specifically designed for repeated deep discharge and recharge cycles — maintaining performance even when discharged to 80–100% DoD. These batteries feature thicker electrodes and optimized electrolytes for high structural integrity. Applications include:
