Battery life cycle management is facilited with distinct visual cues of colors and color-coded combinations. The color-codes enable battery types and characteristics over the course of the life of the battery to be determined. The color-codes are based on a color system that indicates a performance rating of the batteries. A system for managing the color-coded batteries selects color-coded batteries for use based upon color, maintaining color based functionality, and color-coded battery indication for destruction of the battery at the end of its life cycle.

A lead-acid battery includes: a housing that includes a container including one open end and a lid closing the opening of the container; and an element that includes a plurality of positive electrode plates and a plurality of negative electrode plates alternately arranged in the container with a separator interposed therebetween. Each positive electrode plate includes a first foot protruding toward a bottom face of the container, and each negative electrode plate includes a second foot protruding toward the bottom face of the container. The first foot and the second foot are disposed at positions different from each other when viewed from the arrangement direction of the elements. A rib, which extends from an end of a specific region sandwiched between a row including a plurality of the first feet protruding from the element and a row including a plurality of the second feet protruding from the element and divides at least a part of the specific region into a plurality of regions, is formed on the bottom face of the container when viewed from a direction perpendicular to the bottom face.

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).

A grip portion (90) of the handle (23) is located on an outer periphery of a first projecting portion (21).

A battery cover is disclosed. The battery cover has a lower battery cover and an upper battery cover. The upper battery cover is matable with the lower battery cover to form a labyrinth and a plurality of battery cover sides. The labyrinth has a plurality of labyrinth cell passageways between a plurality of cell openings and a plurality of mixing areas, and the labyrinth cell passageways extend above an acid level when tipped all directions onto the battery cover sides from an upright orientation.

A lead-acid battery (100) is provided with a lid (14). An external flow passage (530) communicating with a communication chamber (520) through a vent hole (321) and communicating with a discharge port (405) of a lid (14) is formed inside the lid (14). A compartment fence (452, 454) continuously extending over the entire width of the external flow passage (530) is formed in the external flow passage (530). A residual volume is larger than the volume of the communication chamber (520), the residual volume being obtained by subtracting, from the total volume of a plurality of external spaces (460, 462, 464) divided by the compartment fence (452, 454), the volume of the discharge-side external space (464) closest to the discharge port among the plurality of external spaces.

A lead-acid battery includes an electrode plate assembly, a battery case, a positive electrode strap, a negative electrode strap, a positive electrode post, a negative electrode post, a cover, and an electrolyte solution. A negative electrode bushing provided in the cover and the negative electrode post together constitute a negative electrode terminal. A maximum value of a gap between an outer circumferential surface of the negative electrode post and an inner circumferential surface of the negative electrode bushing in the negative electrode terminal is 0.5 mm or more and 2.5 mm or less. A rib is provided in a lower part of the negative electrode bushing, and a minimum value of a protrusion height of the rib is 1.5 mm or more and 4.0 mm or less. A distance between a surface of the electrolyte solution and a lowermost portion of the negative electrode bushing is 15 mm or less.

The present disclosure pertains to motion-generating particles for desulfation of lead-acid batteries, lead-acid batteries including such motion-generating particles, and methods of making and using the same. For example, the present disclosure provides a lead-acid battery including one or more electroactive plates disposed within a casing; an electrolyte disposed within the casing and surrounding the electroactive plates; a plurality of ferromagnetic particles disposed with the electrolyte within the casing; and one or more electromagnets. The one or more electromagnets may be configured to direct a magnetic field towards the electrolyte to selectively cause movement of the plurality of ferromagnetic particles so as to agitate the electrolyte.

A vehicle battery that includes a partially hollow battery shell, shock-absorbing material, and a mounting base. The battery shell has an upper section and a stepped-in lower section, the lower section having a sidewall and a floor. The shock-absorbing material is attached to the sidewall of the lower section of the battery shell and has a lower edge that extends below the floor of the lower section. The mounting base is attached to the lower edge of the shock-absorbing material and is spaced from the floor of the lower section of the battery shell to isolate the battery shell from a vehicle surface on which it is supported.
