Abstract: The invention relates to a mixing element designed to be installed into a housing of a liquid electrolyte-operated electrochemical accumulator in order to mix the electrolyte as a result of forces and/or motion exerted on the accumulator during operation, wherein the mixing element is designed as a hollow body provided with at least one respective opening at opposite end regions such that a channel is formed in the hollow body which leads into the at least one respective opening in the opposite end regions and is circumferentially delimited there by the material of the mixing element, wherein the mixing element comprises one or more securing and/or spacer ribs protruding from the external side of the mixing element and designed to contact parts of the accumulator housing in order to fix the mixing element in the accumulator and/or set a specific position of the mixing element relative to the housing parts.

Abstract: A compact AGM lead acid battery is disclosed. The battery has a container and one or more electrically connected cells in the container. The electrically connected cells are formed by a plurality of positive plates and plurality of negative plates, wherein an absorbent glass mat is interleaved between positive and negative plates. Electrolyte is provided within the container. The lead acid battery has an improved battery performance per volume and less lead weight than a conventional AGM lead acid battery or EFB lead acid battery.
