Abstract
Apparatus for charging a battery (5) includes a battery compartment for accommodating the battery in a manner such that its electrical terminals are in contact with a pair of electrodes. The electrodes are connectable to respective poles of a controllable source of electrical energy. A resistive strain gauge (15) for monitoring mechanical deformation of the battery is attached to an elastic surface within the battery compartment, against which surface the battery is pressed when it is located in the battery compartment. In a particular embodiment, one of the electrodes (9) is a sprung metallic sheet and the elastic surface is located on this sheet.
