Deep cycle batteries-to my knowledge, are made to withstand numerous re-charging periods. Deep cycles are typically ones you would use (for instance) for electric motors on a boat when you go out fishing- it will drain (since you can't just charge it in the middle of a lake)- but will recharge many more times before going bad as compared to a regular auto battery. You take a regular auto battery, discharge it and recharge it numerious times, and soon enough the acid inside will become just as useless as water, it will not hold electric charged particles and the battery will be toast. Again, deep cycle batteries will take vast amount of time before this process happens. Also you might kill a deep cycle by giving it constant charge as an alternator would in a car. These batteries are widly used in marine applications. -You get the idea -Dan Benedek #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
