All batteries degrade over time, but our new power stations use the latest Lithium Iron Phosphate (LiFePO4 or LFP) battery technology to slow down degradation and give your products the longest possible lifespan. Today we’re covering how to optimize your battery lifespan for as long as possible. 

The LFP batteries in our new products have a 4,000+ cycle lifespan.* (This adds up to about 10 years of daily use). At the end of those 4,000 cycles, the battery will still have about 80% of its original capacity. For example, after 4,000 cycles, the Yeti PRO 4000 will have about 3,200Wh of capacity after 4,000 cycles.  

* To 80% of original capacity at 75° F with .5C charge and discharge. 

What counts as a cycle? 

A cycle starts with your power station at 100%. From there, once you use it until it hits 0%, and then charging it back up to 100% counts as one cycle. 

Which Goal Zero Yeti Power Stations have LiFePO4 batteries? 

All our 6th generation power stations have LFP battery technology, including the Yeti PRO 4000, Tank PRO 4000, Yeti 700, Yeti 500, and Yeti 300. 

How To Get the Best LiFEPO4 Battery Performance and Prevent LFP Battery Degradation 

Get the best performance and lifespan out of your LFP battery by following the tips below:  

Do not use third-party chargers 

The charging cables that come with your power station are optimized to provide the correct voltage and current levels required for safe and efficient charging. Never charge your power station with a third-party device. This could damage your power station or result in a safety issue.  

Store partially charged at room temperature 

If you don't plan on using your power station for a while, charge it to about 50%, power it off, and store it at room temperature. This gives you standby power when you need it. Your power station can handle temporary exposure to extreme temperatures without permanent damage, but avoid long-term exposure to extreme heat or cold to help your battery last as long as possible.  

Keep power levels below the maximum when possible 

Using your power station at the maximum power level won’t damage it. Maximum power levels allow you to recharge the power station faster. However, running at maximum power can reduce your battery’s lifespan. If you have time to recharge your power station at a lower rate, it will prolong battery life (and it will be quieter). To learn how to adjust your charge rate, check your user guide. 

Avoid draining your battery completely every time 

Staying between 20% and 80% State of Charge will help your battery last longer than draining it or charging it completely on each use. However, if the battery is not allowed to periodically reach 0% and 100% the State of Charge data can become less accurate over time. To prevent loss of accuracy, we suggest draining the battery completely and recharging the battery completely once every 10-20 cycles.  

Avoid use in extreme temperatures 

These power stations are built for indoor and outdoor use and can handle extreme conditions without safety risks. However, you can extend battery life by using your power station in moderate temperatures (60 to 100° F) as much as possible.  

Taking these steps to protect your battery helps ensure that you can use your Yeti power station for years to come, whether you’re using it for emergency backup, RV power, camping, or other outdoor adventures.
