How Does Temperature Affect My Battery?

How Does Temperature Affect My Battery?


EXP PRO Batteries are particularly popular with the outdoor adventurer. The shock resistant design ensures they can go the distance, and the port covers keep out dirt and grime along the way. 

So what happens when you go to these in colder climates and need to utilize your battery? Or you have a desert-like destination in mind and the heat is cause for concern? Thankfully, EXP PRO Batteries have a wide operating temperature range.

Let's explore the numbers:

EXP PRO Battery Temperature Guide:  Storage -4°F to 132°F. Discharge Operating  -4°F to 132°F. Charge Operating 32°F to 132°F.
When storing your EXP PRO battery the safe temperature range is -4°F to 132°F. For storage greater than 3 months, the general rule is to store at 40-50% of capacity, or having only 2 indicator lights lit. 
While using your EXP PRO battery to charge and power your devices the temperature range is also -4°F to 132°F. This can also be referred to as discharge operating. This is a great advantage for those colder adventures.
Charging your EXP PRO battery requires a temperature range of 32°F to 132°F. The charge operating temperature requires the battery to not be below freezing. 

LiFePO4 (Lithium Iron Phosphate) technology has been proven to be the most chemically stable option. If you subject a LiFePO4 battery to harsh temperatures or accidents it won't start a fire or explode. It can be stored and discharged at the upper and lower temperature limits. Plus, exposing the battery to a variety of temperatures will not affect the reliability. 

The primary concern with other batteries, specifically lithium ion (Li-Ion) batteries, is safety. They are extremely sensitive to high temperatures and inherently flammable. The average discharge operating temperature is only 14°F to 104°F, while some experts say the temperature range for the popular Li-Ion NMC chemistry is only 32°F to 104°F. Users need to be conscious of usage during hot summer days, and the higher temps of sought-after desert adventures. Overcharging and overheating can cause fire and explosions. Lower temperatures can also cause malfunction, rendering your battery useless, perhaps in a time of need. The charge operating temperature of Li-Ion is restricted to 32°F to 104°F. While you may never experience extreme temperature ranges, it's good to keep versatility in mind when selecting an additional power source. 

When safety and longevity is desired LiFePO4 is the superior option. EXP PRO is committed to providing safe, non-toxic batteries that will perform for years. 

Have you misplaced your charging cord? You're not the only one! We offer replacements. Charge your battery at home with the AC power charger, or charge your battery on the go in your car with the DC power charger

    Great question. Here at EXP PRO we have definitely taken steps to help protect the battery from moisture exposure with our covered ports and also by providing a protective sleeve. The sleeve is water repellant for a short time, but water does eventually soak through. I like to think of the battery like my cell phone when exposing it to the elements. A little moisture, rain, etc. shouldn’t cause much trouble, but definitely recommend avoiding prolonged or heavy exposure. I don’t believe fog would cause any issues as long as ports are kept covered when not in use. Please feel free to reach out if you have any further questions.

    While I note temperature ranges, I do not see anything about exposure to moisture, fog, mist, rain nor snow. Can the OEM pls comment on this type of exposure and whether the travel pouch it comes in is weatherproof, or should not be used in case of fog please, or any other user.
