Does altitude affect batteries. we wondered the other day. After all, we do get tired more quickly on top of mountains, where water for our coffee boils faster. Because batteries contain energy there must be a connection, we thought. Moreover, our autos go faster at sea level too.
The Effect of Altitude on Camera Batteries

There were early stories of iPod hard discs crashing, although we believe that is fixed. However, mountaineers still report camera, laptop, and phone battery capacity falling by up to one half. However, in this instance, the question does altitude affect batteries, does not apply directly.
Because it is actually the cold causing the ions to shuttle slower between the terminals. Here the solution is to snuggle up to your camera battery at night. Just make sure there is nothing metallic that could cause a short. Batteries feel the cold and heat and metal can short-circuit them.
The Intriguing Matter of Battery Arcing

When electricity flows between two points through the air, it produces a glow. Scientists call this phenomenon ‘arcing’. Lightning is nature’s response to the event. Arc welding uses the same principle with AC or DC current. The insulating characteristics of air limit the speed at which this happens.
Thus, we can expect faster arcing, and greater energy consumption, at higher altitudes with thinner atmospheres. So does altitude affect batteries this way? Definitely. In a related manner, engineers place communication towers atop mountains because this increases transmission range.
How Does Altitude Affect Batteries in Deep Space
The question is somewhat irrelevant, because it poses the question, above what. However, it does get extremely cold in space away from our sun, and this has implications for space exploration. NASA makes extensive use of lithium batteries because they are compact, lightweight, and dense.
However, it uses radioactive isotopes to power rovers on the surface of Mars because they consume large amounts of energy. Thus, the answer to the question does altitude affect batteries directly on earth is yes, but not as directly as one might have thought.
