Storing Spare Batteries
Store spare GPS batteries in a waterproof pouch or hard case to protect them from moisture and extreme temperatures. Consider using a case with individual compartments to separate batteries and prevent short circuits. Store the pouch or case in an easily accessible location, such as on your person or in a readily available backpack pocket.
Battery Sizing and Quantity
Consider carrying a minimum of three sets of batteries for each GPS device in your emergency kit. This allows for multiple days of navigation in case your primary batteries fail. If you plan to be away from civilization for extended periods, consider carrying additional batteries or a portable power source.
