Claim Text:
1. A device powered by a plurality of batteries held in a series configuration in a battery compartment, wherein each of the plurality of batteries is comprised of a metal can which holds a cathode, an anode and a current collector, said can having a first end with a first contact having a first polarity and a second end with a second contact having a second polarity, said two or more batteries having a terminal battery in which its second end is a terminal end of the series configuration which is held proximate to a terminal retaining member of the battery compartment, comprising: for each pair of batteries of the plurality of batteries held in the series configuration, a spacer positioned between the first end of a second battery and the second end of a first battery of the plurality of batteries, wherein the spacer has a thickness sufficient to prevent the first end of the second battery from contacting the second end of the first battery; and for each spacer, a resilient contact which provides a resilient electrical contact between the first end of the second battery and the second end of the first battery; wherein each spacer is made of a shock absorbing material and is comprised of: a first resilient contact orientated toward the first end of the second cylindrical battery; and a second resilient contact orientated toward the second end of the first cylindrical battery; wherein the first and second resilient contacts are held by the shock absorbing material; and wherein the first resilient contact is comprised of a first plurality of resilient ears and the second resilient contact is comprised of a second plurality of resilient ears.
