If you begin to suddenly have trouble connecting to AltimeterThree from your phone—or downloading flights—it may be because your battery is low.
It’s a good idea to keep your altimeter fully charged, and that goes for any product you might have that uses a rechargeable lithium battery. Lithium batteries like to be kept fully charged, and it doesn’t hurt to leave them in the charger. Smart circuitry prevents them from being overcharged, and the added power will prevent AltimeterThree’s wireless radio from dropping out and spoiling your connections.
