Why Lithium batteries and not Alkaline batteries?
Energizer e2 Lithium Batteries have, in our extensive testing, proven to be constant and reliable. Note: Lithium Batteries will allow for consistent operation. However when lithium batteries start to loose their power, the power will drop quickly so please dont ignore the power indicator light and be sure to change the batteries when the Roscoby begins to notify you that the power is running low. – Safety precautions when using lithium batteries: Lithium batteries, when not properly stored or inserted into the battery tray, can overheat and may cause a fire. Please store and use the batteries properly.
