Estimote Beacons are designed around a non-removable Panasonic® CR2450 or CR2477 battery in case of hardware revision 3.4. The ideal operating temperature is 23°C (73.4° F). At this temperature, the battery can operate up to 2 years in the case of Proximity Beacons and 5 years for Location Beacons. Stickers' battery life is up to 1 year.
Battery lifetime marginally reduced
60°C (140°F) - maximum temperature
Battery lifetime dramatically reduced

Low Battery Level and Estimote Beacon Behavior
As the battery ages your Estimote Beacons will continue to operate as normal but as the battery level approaches a critically low threshold, the Bluetooth radio will begin to exhibit interrupted or truncated radio signals. Once this behavior is exhibited, the beacon will no longer be able to sustain radio presence and the device should be replaced or you may choose to disassemble the beacon and replace the battery, doing so will revive the hardware back to normal operation.
Monitor Battery Power
You can monitor the level using Estimote Demo app in connectivity mode.
Using Beacons Outdoors
Estimote beacons are water resistant and can be placed outdoors in otherwise adverse conditions. Battery longevity is affected by temperature fluctuations, as such, you should carefully review the necessity of deploying in particularly cold or hot environments.
