Ni-MH rechargeable battery	8.4～10.0	550	0 – 45

Batteries are covered by 6 month warranty support.

	CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.
	Battery should not be disposed of into general household waste. Bring damaged or worn-out batteries to your local recycling center or dispose them into a battery recycle bin commonly found in supermarkets.

Battery tests

The amount of time the device will work from internal battery depends on the battery health, how often the device saves/sends information to the server, external peripherals connected to the device and the results may also differ depending on firmware used.

For general comparison purpose, and to see what results can be achieved, you can refer to the following internal test results in different modes and sending frequencies:

Mode:	Min Period (data saving frequency)	Send Period (data sending frequency)	Starting Voltage	Cut off Voltage	Time achieved
Operating	10 seconds	60 seconds	10,1V	7,6V	438 min (7 hours 18 minutes)
