Abstract
A battery arrangement is used with a distance and speed measuring indicator for cycles. Two batteries can be accommodated and electrically connected in a battery chamber, so that in battery replacement the old battery can remain in the battery chamber and in electric connection with its contact terminals until the new battery is inserted into the battery chamber and is in electric connection with the contact terminals. In this way; during battery replacement, the loss of the data stored in the memory of the appliance is prevented.
