Abstract
Apparatus to rapidly bulk charge a lead acid battery used in a 'standby' power supply unit (PSU), or similar equipment containing said function, such as in an alarm panel system, fire panel (system) etc., without increasing the output capacity of the regulated PSU, significantly increasing its dissipation, size or cost, or causing an unacceptable recharge time of (often) several days. The apparatus comprises minimal additional components to provide a bulk charge of approximately 70% capacity to a 65 Ahr battery within 14 hours, while only drawing an average current of approximately 0.4 amp from the regulated PSU.
