Andy is correct, Batteries that sit and not used will build up a hard
crystal substance inside and the longer it goes the worse it is. 
There is nothing you can do but buy another battery. If you don't want to do
what Andy does every month then you can buy a Battery Tender at Wal-Mart and
it will cycle the charging automatically. They carry the 1.5 amp model that
would be perfect for long term sitting.

Re: Batteries(long)

I would much rather take my battery out, leave it on my workbench, and
trickle charge it overnight once a month than to open it up than  risk
ruining an $80 battery.  

Even if it seems ok, I would not be sure if I could trust it on long trips.

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.
