</font><font color="blue" class="small">( ............ When neither my regular battery charger nor my Battery Tender could bring it back to life I took it to a local auto parts store. They checked it and it appeared dead, so they tried to charge it. It charged right up. ...........Thanks,

When charging a dead battery, it is best to bring it to room temperature first. Trying to charge a dead, cold or even frozen battery can lead to disastrous events. Whenever a battery goes completely dead, the electrolyte in the battery, separates the water portion of the electrolyte from the acid part of the electrolyte and the water portion can and will freeze. I have seen totally discharged batteries both freeze and crack. It is totally temperature dependent. Always bring the battery inside and wait 24 hours to assure complete thawing and then put a trickle charger on the battery for a few hours. Make sure to correctly hook up the Positive and Negative, because in the totally discharged state, it is possible to reverse the polarity of the battery. A cold discharged battery that you are trying to jump or charge, is like handling a stick of dynamite. If you don't handle it properly it can and will explode. In my EMS days, I had seen it happen all too often.
