re lead acid batteries concrete in article apr cronkite ocis temple edu camter astro ocis temple edu carter ames writes i was just wondering one thing actually two i hope that this is the proper place to post this subject why does a lead acid battery discharge and become dead totally unuseable when stored on a concrete floor i decided to bring the battery in from the lawn mower and the motorcycle from the unheated garage this year to preserve them and i just went to use them and noticed that not only do they not work but they act like the two terminals are shorted i asked a friend and he said that you should never do that cause it ruins them but he couldn t tell me why thanks camter astro ocis temple edu i am not a battery expert but from recent reading a lead acid battery will self discharge at a relatively high rate and if stored in a discharged state will develop a condition i think is called sulfation in storage either the electrolyte should be removed and replaced for use fat chance i d ever do that at home or the battery should be stored on a trickle charge i have also i think read that the condition may be reversable if hooked up to a current limited charging circuit fro a long period of time the refernce i remember is to use c where c is the amp hours as the charging circuit and leave it hooked up for weeks some of this may only apply to gel type cells but i suspect the same applies to the liquid type richard dell
