Abstract
A method for the manufacture of lead-acid batteries and associated apparatus and a lead-acid battery design resulting therefrom is disclosed. The method involves providing a battery grid and pasting the grid with a battery paste such that a profiled and tapered battery plate is formed. This battery plate is wrapped onto a coil and cured in curing apparatus. A battery element is formed using coils of the finished plate stock, separator material, and winged end plate. After this, several battery elements are then placed into a battery container.

A method of making battery grid strip for battery plates for use in lead-acid batteries comprising the steps of
- providing a battery grid material, and
- forming said battery grid material into a battery grid strip having a reticulated grid strip portion, a lug strip portion disposed on one side of said reticulated grid strip portion and a border strip portion disposed adjacent to said reticulated grid strip portion on the opposite side of said reticulated grid strip portion from said lug strip portion, said lug strip portion having at least one section that is an outwardly projecting protrusion.
A method of making battery grid strip for battery plates for use in lead-acid batteries comprising the steps of
- providing a battery grid material,
- forming said battery grid material into a continuous battery grid strip having a reticulated grid strip portion, a lug strip portion disposed on one side of said reticulated grid strip portion and a border strip portion disposed adjacent to said reticulated grid strip portion and disposed on the opposite side of said reticulated grid strip portion from said lug strip portion,
- forming said lug strip portion having a first strip portion and a second strip portion with said first strip portion having an average thickness greater than the average thickness of said second strip portion,
- providing said lug strip portion with at least one section having a protrusion which projects outwardly from the surface of said lug strip portion, and
- severing battery grids from said battery grid strip at predetermined locations along the length of said battery grid strip, whereby battery grids of any desired length can be made from said battery grid strip.
