There is a growing need to develop novel processes to recover lead from end-of-life lead-acid batteries, due to increasing energy costs of pyrometallurgical lead recovery, the resulting CO 2 emissions and the catastrophic health implications of lead exposure from lead-to-air emissions. To address these issues, we are developing an iono-metallurgical process,

Only 12 Volts Lead Acid Batteries up to 200Ah can be Discharge ! Because of measurement offset (to achieve better Voltage Measurement Resolution) only Voltages from 10.1 V to 14.7 V can be measured, which means any voltage below 10.1 volt will read 10.1 volt. Besides, a 12 Volt Lead Acid Battery that reads 10 volt is practically Dead !
