Since we are on the subject of batteries... And this may sound far fetched... But..Is this situation possible...I was given a very nice 18hp key start riding mower,that had sat garaged unused for 4 years of it's 6 year life... I got it home and tried to start it...the battery was Stone dead,not a once of life to it... So I took it out and checked the cells all were BONE DRY....so I added distilled water and filled all the cells to the proper level,then I figured...I will try to charge it....I put it on the charger(automatic charger) two hours later the charger clicked off and the green led on the charger came on telling me the battery was FULLY CHARGED..... I really could not believe that a lead cell battery that was used for two years..then sat connected to the lawn tractor for another 4 years..that was totally discharged...and any traces of water in the cells had evaporated over that four years of not being used...and then reinstalling fresh distilled water FOUR YEARS later and the battery comes back to full life... I did a load test..and yes...it is as if I had just installed a NEW Battery...and works and starts my rider JUST FINE....... My point here for the people in the Delorean community is it possible...... To totally discharge your wet cell battery before you store your Delorean for long term storage and remove the caps off the battery(the "liquid" in a typical wet cell battery consists of water and sulfuric acid) to let the water in the battery evaporate (the sulfuric acid gets absorbed into the lead plates when a battery is fully discharged)Since without the sulfuric acid all that is left is water(h2o) By the way...That is why you never let a battery discharge in the winter as the remaining water will freeze. Could this be a possible way of storing a battery long term without ruining it thru a long term discharge..or having to trickle charge it all the time while not in use. It worked for me(or at least on that one battery) Has anybody tried this method...You might want to check on this possibility..come Hibernation time for your Delorean...anybody else have this type of experience with their wet cell battery. If this turns out to be a way of saving your battery durning a long term storage of your Delorean...it might just be worth spreading this information so that others might benefit and learn about this possible battery saver method.
