The disclosure relates to the technical field of batteries, and provides a battery, a battery apparatus and a battery pack. The battery includes a battery surface and a pole element. The battery surface is provided with a first recess, and the first recess is used to accommodate the pole element of the other battery. The pole element is arranged on the battery surface and is located outside a range where the first recess is located. By providing the first recess on the battery surface, the pole element of the other battery can be accommodated in the first recess when the batteries are grouped.

Implantable medical devices that include a battery to power circuitry utilize a battery connector to electrically interconnect the battery to the circuitry. The battery connector may be mounted directly to a device housing to have the battery connector a fixed position within the device. Battery terminals of the battery are electrically connected to terminals on the battery connector, and the terminals on the battery connector are electrically connected to power terminals of the circuitry. The battery connector may include various features such as mounting grooves formed in a connector body, tapered pins to connect to power terminals on a circuit board, as well as plates to engage the battery terminals. The device housing may provide mounting features that allow the battery connector to be affixed directly to the device housing.

A battery that includes collectors with tabs that are wide with respect to the area of the collector. The wide tabs present a low electrical and thermal resistance to improve the flow of current and/or heat to and from the collector thereby improving electrical and thermal performance of the battery. The battery further includes terminals with a channel that supports the flow of medium (e.g., liquid) to heat and/or cool the battery. The terminals may include fins or pins to increase the surface area of the terminal to improve thermal transfer to and from the battery and collectors of the battery. The batteries may be formed into a battery module that includes a system for monitoring and regulating the temperature of the batteries of the module.

A lid (15) of a lead-acid battery (100) includes a projecting portion (20) projecting from a base portion (19). The projecting portion (20) includes a shaft portion (27) serving as a rotation shaft of a handle (23), and an opposing wall (28) intersecting an imaginary line passing through an axial center of the shaft portion (27). A grip portion (90) of the handle (23) is located on an outer periphery of a first projecting portion (21).
