Q: why battery 9volt very fast drain, with in 4 days
Asked by abyz on 2018-08-08 10:47:56
mgwerner my module draws 4mA (relay off) and 26mA relay ON. SO: I guess a small 9V battery - the one used in smoke detectors - have about 500mAH capacity. IF always ON, battery is empty after about 20 hours If on half the time, 50%, empty after about 40 hours, 1.5 days on 25%, empty after 3days and so on either use a big lead battery with charging every few months, or if you switch mains anyway, a 12V power supply

mgwerner ray is absolutely right! piezos have high impedace, about 1000@ and max. power depends on impedance of bass driver ! refer to www.monacor.de/produkte/components/lautsprechertechnik/pa-hochtoener-und-hoerner/mpt-165/ ELECTRICAL specs are identical for all piezo drivers...
