Bev, You are thinking correct. Lead acid. You want best replacement non-prorated warranty, biggest that will fit, least cost, and a exchange core to avoid the high $10+ core cost. Any core will usually do. Wal-Mart has a big yellow battery, usually a two or three year exchange warranty. Why? Batteries are short-lived. Will last three to five years in your car, but that is used every day or with some regularity. That is good for the battery and is what makes it last. Batteries have cycles. Cycles are limited. You would naturally think that less cycles may mean longer life, but not so. No battery will last sitting in one state. The state of non-use either discharged or charged will most rapidly cause failure versus use. So batteries cannot just sit in any one state. Either use it like if in your car or you must have a deliberate usage you schedule. RV's mostly sit. So to make the battery last it needs to be run down some, and then charged some. No, you don't need to run it dead. No, you must not keep it topped off and constantly charged. So in your rv or collector car use the car one day each month and simulate rv use about once each month and then re-charge it, but don't overcharge it and thus "cook it away" by charging too long. Manufacturers rotate battery stock every three to six months. A new battery six months old on the shelf is considered junk. It is an old wives tale that a battery sitting on the ground or concrete gets the life "sucked" out of it. It is in a plastic case! It simply sits and sulfates. Even if you were to shrink wrap it and put it in your fridge, it would be just as dead. Use is the key to keeping a battery healthy! When you buy a battery, look at the little sticker on it. All are date marked. When using letters, the letters are A thru Z for each month, January equals A, Feb B, and so on. Most batteries have a dual sticker so it is easy to figure out. The sticker will have a color for each month. Sticker will be round. The size of a dime. One half will be D8 and the other half will be 4/8. Retailers are smart. They push the old stock. Don't buy an old battery! Make them give you, or you look to the back and pick the month current. Don't buy a Feb 08 battery! This is April 08! Forget about the CCA (cold cranking amps). Bigger is heavier and is better. Heavier equals more lead. More lead equals more battery. Most charger converters in rv's are the old style and will cook a battery to death so don't just leave it on. Charge for about 4 hours maximum only! Best to buy a cheapy automatic charger from some place like wal-mart, charge till done and disconnect. The old chargers and a lot of new ones will "finish rate" at 15.1 volts or higher. When charging above 14.6 volts indicated, the battery is being destroyed! Keep that receipt and exchange the battery before the warranty period expires. Make sure you run it stone dead if not already dead before you exchange it or the clerk will decide you still have something left and deny the exchange. The warranty period will run off the date you bought it, not off the date sticker on the battery. No need to "over think" batteries. Just buy cheap as you can with the longest warranty non-prorated exchange. Use it at least once a month for at least one to four hours. Then re-charge it the next day for no more than three to four hours. It will last thru the warranty period. I know batteries. I work on electric forklifts, carts, and man-lifts. Most forklift batteries cost $3000. At that cost you must learn batteries and what makes them last or fail. -Eddie- Houston, TX ----- Original Message ----- From: "Bev Harris" <zia@ix.netcom.com> To: <sslist@tompatterson.com> Sent: Friday, April 11, 2008 10:32 PM Subject: [SilverStreak] Newbie battery question > So I'm ready to buy a deep cycle battery for my 64 SS 20 foot Sabre.
