Battery life depends on Accu-Chek Spirit Combo insulin pump use, including daily insulin requirements, frequency of delivery and backlight usage.

For example

If used in a typical usage pattern of 50 Units / day using U100 insulin and normal operating temperature (23 °C ±2 °C [73 °F ±4 °F]) the battery life is approximately:

• Alkaline: 70 days for Bluetooth^® off; or 30 days for Bluetooth^® on
• Lithium: 200 days for Bluetooth^® off; or 80 days for Bluetooth^® on

NiMH: 100 days for Bluetooth^® off; or 40 days for Bluetooth^® on
