How do I maximize the lifespan of my Lithium Polymer FJ batteries?


FJ system Lithium Polymer Batteries are rated for a lifespan of 300 + charge cycles.

You can help maximize and increase that life by charging an FJ battery before it is empty.

Lithium Polymers do not have a memory. Therefore you should never deplete them totally as with other powering options such as Ni-Cad Batteries. Westcott's FJ system has built-in protection to prevent total discharge when in use.  If stored long-term after significant use and discharge, the remaining protective charge can dissipate damaging the batteries ability to recharge.  

Recharging the FJ battery before the battery is 75% depleted can prolong the battery life.

Avoid charging when the battery is below 10ºC/50ºF.  The chemistry in the battery is less efficient below that level.

Hot Lithium Polymer batteries don’t take a charge well and continued overheating of your FJ units will reduce the life and functionality (frames per charge) of the battery.   Allow the batteries to cool after use before charging.  If your FJ unit nears or reaches OH (overheating) status allow additional cooling time.  If using the FJ400, let the FJ400 fan help cool the battery for 30 to 40 minutes before powering off the unit and placing it on the charger.  



Lithium Polymer batteries should not be stored long-term with a full charge. Chemistry in the batteries can cause them to expand when stored for an extended period and may render them unusable.  

Longer term storage levels between 50% and 75% is suggested as Lithium Polymer batteries lose less than 1% of their charge each month when stored.  Therefore, there is little chance they will discharge too far unless stored for a very long time at the lowest levels.  



Significant discharges not only shorten the lifespan but can also damage the battery.   Regularly maintaining charge levels above 25% will enhance the lifespan of your battery.  Follow the directions for charging that come with your FJ product manual.
