How long do lithium-iron phosphate batteries last?

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.

How long does a LiFePO4 battery last?

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.

Do ionic LiFePO4 batteries need maintenance?

Extreme heat or cold while in storage can also mess with the battery’s chemistry, so combine a moderate charge level with proper temperature control for best results. Ionic LiFePO4 batteries are truly zero maintenance—no water levels to top off, no corrosion to clean, and no fussing with terminals. Just install them and go.

Why are LiFePO4 batteries so popular?

First introduced by a research team at the University of Texas in 1996, this chemistry has since become popular for its outstanding safety, durability, and overall reliability. LiFePO4 batteries come with several key advantages: Ultra-long lifespan: Capable of 3,000–5,000+ charge cycles—far exceeding lead-acid and NCM lithium batteries.

Can LiFePO4 batteries be drained?

While LiFePO4 batteries are capable of deep cycling, regularly draining them to near 0% can still shorten their lifespan. As seen in the earlier charging voltage chart, batteries operating in low-voltage zones (deep discharge) are more vulnerable to stress and degradation.

How long does a lithium battery last?

Daily use and regular charging help maintain the battery’s chemistry, while letting it sit unused for too long can lead to self-discharge and reduce battery health over time. For example, a 100Ah lithium battery running a 100-watt device could last about 11 to 12 hours on a full charge.
