How to Optimize Your LiFePO4 Battery's Lifespan

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. 

Please visit our website for more information on this topic.

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 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 , Tank PRO , Yeti 700, Yeti 500, and Yeti 300.

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.

LiFePO4 (Lithium Iron Phosphate) rechargeable batteries are known for their high energy density, long cycle life, and excellent performance. To maximize the lifespan and performance of LiFePO4 batteries, it is important to follow certain guidelines and best practices. Here are some tips to help you get the most out of your LiFePO4 rechargeable batteries:

1. Choose the Right Battery Capacity:

Selecting the appropriate battery capacity for your application is crucial. Ensure that the battery capacity is sufficient to meet the power requirements of your devices without excessive strain. Overloading the battery regularly can reduce its lifespan.

2. Avoid Overcharging: 

LiFePO4 batteries have a recommended charging voltage range. Overcharging the battery beyond this range can lead to overvoltage, which can degrade the battery's performance and reduce its lifespan. It is important to use a charger specifically designed for LiFePO4 batteries and set it to the correct charging parameters.

3. Optimal Charging:

LiFePO4 batteries should be charged at a moderate rate. Fast charging or high charging currents can generate excessive heat and cause stress on the battery, leading to reduced capacity and cycle life. Follow the manufacturer's recommended charging current for the battery and avoid rapid charging unless necessary.

4. Avoid Deep Discharging: 

While LiFePO4 batteries are more tolerant to deep discharges compared to other battery chemistries, frequent deep discharging can still affect their lifespan. It is recommended to avoid deep discharging whenever possible and recharge the battery before it reaches critically low levels. Deep discharges can lead to irreversible capacity loss and reduce the overall cycle life of the battery.

5. Maintain Optimal Operating Temperature: 

LiFePO4 batteries perform best within a specific temperature range, typically between 0°C and 45°C (32°F to 113°F). Extreme temperatures, both high and low, can negatively impact the battery's performance and lifespan. Avoid exposing the batteries to extreme heat or cold and store them in a temperature-controlled environment when not in use.

6. Storage Recommendations: 

If you need to store LiFePO4 batteries for an extended period, follow these guidelines to maintain their performance:

   a. Charge the batteries to approximately 50-70% of their capacity before storage.

   b. Store the batteries in a cool, dry place away from direct sunlight and extreme temperatures.

   c. Check the battery voltage periodically during storage and recharge if it drops below a recommended level to prevent over-discharge.

7. Use a Battery Management System (BMS): 

A BMS helps monitor and protect LiFePO4 batteries during charging and discharging. It helps maintain balanced cell voltages, prevents overcharging and over-discharging, and provides temperature monitoring. Using a BMS ensures the safe and optimal operation of the battery, maximizing its lifespan.

8. Regular Maintenance: 

LiFePO4 batteries require minimal maintenance, but it is still important to periodically inspect them for any signs of damage or corrosion. Clean the battery terminals with a soft, dry cloth if necessary. If you notice any abnormalities or significant decreases in performance, consult the manufacturer or a qualified professional for assistance.

9. Avoid Extreme Conditions: 

LiFePO4 batteries should not be subjected to extreme physical conditions such as impact, vibration, or excessive pressure. These conditions can damage the internal components of the battery and reduce its overall performance and lifespan.

10. Purchase from Reputable Manufacturers: 

When purchasing LiFePO4 rechargeable battery, choose reputable manufacturers that adhere to quality standards and have a proven track record. High-quality batteries from reliable manufacturers are more likely to provide optimal performance and longer lifespans.

By following these tips, you can maximize the lifespan and performance of your LiFePO4 rechargeable batteries, ensuring reliable power for your devices and minimizing the need for frequent replacements. Remember to always refer to the manufacturer's guidelines and specifications for specific recommendations regarding your LiFePO4 batteries.
