I've recently tried connecting a battery on the DC side of a bridge rectifier with the AC side connected in series with the lighting ring (240v@12mA to 3A depending on how many lights are on). Is there any serious problems with doing this apart from the mains voltage being present on the battery terminals? As i understand, this configuration drops about 12v on the lighting ring, the lights are all cfl and i believe they are wide voltage range ones (85v to 264v).
My dad has been doing this for a while to charge a lead acid battery for the door bell, and believes this is a 'free' 12v battery charger, but i think there must be some disadvantages to it.
