Official range is 0°C - 45°C / 32°F - 113°F for charging Li-Ion batteries - outside of this range and the cycle life will be affected in some way.
How do I charge my solar charger in hot temperatures?
When charging devices in hot temperatures here are a few tips to make sure you get the most of your solar charger. To help make solar charging in heat easier, we recommend purchasing a 10 Foot or 4 Foot extension cable so that you can keep the battery in a a shaded area while charging.
In fact, for every 2.5 degrees over 25° C (77°F) the average solar panel output will drop by 1%. This is because as the ambient temperature rises, the panel itself heats up causing the output voltage to drop. For temperatures above 25°C (77°F), follow our Solar Charger Tips for Hot Temperatures below.
How do I choose a solar panel for a hot climate?
When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F). Panels with a lower temperature coefficient, closer to zero, perform better in high temperatures.
What temperature should a voltaic battery be charged at?
Hot temperatures can not only cause a significant decrease in battery capacity but can cause the battery's over temperature protection to kick in and shut the battery off. The recommended charging temperature for all Voltaic batteries is between 0-45°C (32-113°F) and the recommended storage temperature is -20-35°C (-4-95°F).
Can extreme heat affect a solar charger?
Just like your phone and other electronics, extreme temperatures can affect the performance of a solar charger. In this post we'll go over how extreme heat can affect both our solar panels and external battery packs as well as some tips for using solar chargers in hot weather.
What temperature should a lithium ion battery be charged?
The recommended charging temperature for all Voltaic batteries is between 0-45°C (32-113°F) and the recommended storage temperature is -20-35°C (-4-95°F). For temperatures on the high end of these ranges, use our Solar Charger Tips for Hot Temperatures below. We do not recommend using lithium ion batteries in temperatures outside these limits.
