A method of making battery plates for lead-acid batteries includes providing a strip of material comprising lead; and punching material out of the strip to form a grid comprising wires having a non-rectangular cross-sectional shape by utilizing a die set comprising a plurality of male die components and female die components, wherein each of the male die components comprises a first portion having a first cross-sectional shape and a second portion having a second-cross sectional shape. A single punch of the material creates a hole in the material and also forms the periphery of the hole.

Sealing system for lead-acid batteries for heavy vehicles, having a cap which includes, on one hand, a system of labyrinths intended to avoid electrolyte leaks, providing a centralised outlet; and on the other, multiple plugs for the battery elements, which provides a single point of access to more than one cell at the same time to allow them to be filled simultaneously. These characteristics are combined in a cap that is even with the level of the cover and that is also substantially thermally insulated from the rest of the battery, which condenses emitted vapours, while at the same time reducing vapour emission, and facilitating the return of the condensed liquids to the interior of the element due to the special geometry of the piece, all of which results in a battery for heavy vehicles such as trucks, that can be considered to be maintenance-free.

Determining a state of charge (SOC) of a rechargeable battery includes using a first process to determine a first value for the SOC of the battery and using a second process to determine a second value for the SOC of the battery and deriving the SOC as a weighted average of the first value for the SOC and the second value for the SOC. During a charging cycle of the battery an input charge of the battery is determined from an input current flowing into the battery and a charging time. During a discharging cycle an output charge of the battery is determined from an output current flowing out of the battery, a discharging time and an actual capacity of the battery is the sum of the input charge over charging cycles minus the sum of the output charge over discharging cycles.

An Advanced Graphite, with a lower degree of ordered carbon domains and a surface area greater than ten times that of typical battery grade graphites, is used in negative active material (NAM) of valve-regulated lead-acid (VRLA) type Spiral wound 6V/25 Ah lead-acid batteries. A significant and unexpected cycle life was achieved for the Advanced Graphite mix, where the battery was able to cycle beyond 145,000 cycles above the failure voltage of 9V, in a non-stop, power-assist, cycle-life test. Batteries with Advanced Graphite also showed increased charge acceptance power and discharge power compared to control groups.
