Claims20
A lead acid battery comprising no exposed lead, the lead acid battery comprising:
- a housing having an exterior and an interior, wherein the housing includes a cover;
- a positive terminal composed of lead extending through the housing or the cover from the interior of the housing to the exterior of the housing;
- a negative terminal composed of lead extending through the housing or cover from the interior of the housing to the exterior of the housing;
- wherein the positive terminal comprises a lead-free coating on the positive terminal, the lead-free coating covering the entire positive terminal on at least the exterior of the housing;
- wherein the negative terminal comprises a lead-free coating on the negative terminal, the lead-free coating covering the entire negative terminal on at least the exterior of the housing;
- and
- wherein the lead-free coating on the positive terminal and the negative terminal form a lead acid battery having lead terminals and comprising no exposed lead on the exterior of the battery.
A battery terminal for a lead acid battery, the battery terminal composed of lead and comprising a lead-free coating covering the entire terminal on at least an exposed surface of the terminal when placed on the lead acid battery, wherein the lead-free coating on at least a side of the battery terminal is conductive.
A battery terminal bushing for a lead acid battery, the battery terminal bushing composed of lead and comprising a lead-free conductive coating covering the entire terminal bushing on at least an exposed surface of the terminal bushing when placed on the lead acid battery.
A lead acid battery comprising no exposed lead, the lead acid battery comprising:
- a housing having an exterior and an interior, wherein the housing includes a cover;
- a positive terminal composed of lead extending through the housing or the cover from the interior of the housing to the exterior of the housing;
- a negative terminal composed of lead extending through the housing or cover from the interior of the housing to the exterior of the housing;
- wherein the positive terminal comprises a lead-free conductive coating on a side of the positive terminal, and a lead-free non-conductive coating on a top of the positive terminal;
- wherein the negative terminal comprises a lead-free conductive coating on a side of the negative terminal, and a lead-free non-conductive coating on a top of the negative terminal;
- and
- wherein the lead-free coating on the positive terminal and the negative terminal form a lead acid battery having lead terminals and comprising no exposed lead on the exterior of the battery.
