10 Ah rechargeable battery is included in your purchase. The battery will start to run down if it is not recharged. Therefore, the system requires either a solar panel or an AC adapter plugged in to ensure the battery does not run too low. Even rechargeable batteries eventually fail, and will not be able to be recharged. However, you can order replacement batteries when the time arises. HOBO data loggers require HOBOware software and a communications cable (#CABLE-USBMB). HOBOware Pro Mac/Win has the USB cable included in your purchase. (#BHW-PRO-CD)
