That is dependent on the battery. The manufacturer will have an answer. If you do nothing other than what you describe, eventually the electrolyte level will get below the plates; the plates will warp and the battery will die. That will be true for most lead-acid deep discharge batteries. Life span would likely be less than a year. If you have something like a Surrette 8CS25P, and you float it at the correct voltage; check the electrolyte level at appropriate intervals; and perform an equalizing charge every six months or when needed, the battery should last at least ten years, and probably quite a bit longer — perhaps double that. –ron
Response:
It depends on the plate chemistry, preventive maintenance and charging voltages. Please see Section 11 in the Car and Deep Cycle Battery FAQ on www.batteryfaq.org for table on expected battery service life.

Sorry I don’t know the Quad 4, but in that era the likeliest problem is the alternator or maybe the computer. There may be other modules in the distributor which can fail with reversed poplarity.

Response:
Hi. First, I know nothing about car maintenence at all, so please try to explain things simply. There was transmission work done on it about a month ago and they failed to connect the battery tightly, leading me to think that the battery had gone dead because I couldn’t start the truck at all. When I took it in to get the battery changed, the mechanic tested it first and said that it was still good. He tightened the terminals and everything was fine until today. When I was driving I noticed that when I went to put down the window the battery meter would go crazy back and forth. If I tried to put two windows down and once the batter warning light came on. When stoped the truck and turned off the engine then tried to start it up again immediately after, there was no power at all. After waiting 5 minutes, I tried again and it started, but cranked really slowly. What should I do? I konw the first place to start is to clean the corrosion off the terminals because that’s what the mechanic told me. I know it’s a relatively simply procedure, but I have no idea what to do. I know you’re supposed to use baking soda and water to neutralize the sulfuric acid, but is it safe to just pour it on the terminals like that? I also know you’re supposed to disconnect the terminals and use a wire brush to clean it off. So if someone could give me the exact step-by-step procedure I think I can handle it. Or if you think it’s something other than just terminal corrosion, please feel free to say so. BTW-the truck is a 1994 Explorer with about 50k miles and the battery has never been changed. Thanks so much.
Response:
Original batt on a ‘94? That battery, even if corroded, is due for changing–get a new one–and that way you don’t need to worry about cleaning it for a while. Now, yes, if you set out to clean a battery, disconnect both the negative and positive terminals, in that order. Then lift the batter out of the car and place it somewhere to clean it but try not to put it on cold cement floor. Use wire brush to brush off terminal(s), one at a time and be careful not to touch anything metal between the two terminals so there is touching between the two terminals..it will arc/spark and maybe cause an explosion. Then mix a solution of water and baking soda and pour it over the top of each terminal, slowly. Wipe off entire battery with an old rag and throw the rag away, as it will have some residue of battery acid on it and will deteriorate the rag and anything else it comes into contact with. When dry, put the battery back in the car…..oh, before hand check the metal holders and wipe/clean it up some…..tighten down the positive cable first and then the negative cable. Good Luck! — Take Care and Have a Good Day. CUL8R, Mike

Response:
The steps recommended while good solve half of the potential problems. The battery connectors can become coated with sulfuric acid and corrosion like the battery terminals. Clean the inside and outside surfaces of the connectors with a battery terminal brush or a stainless steel brush. Don’t get overly aggessive if the cable uses a lead type clamp as the clamp can only close so far on the post ( this assumes you have a post type battery connection), Dip the cleaned connector into the baking soda solution. Dipping the connections and a segment of the attached wires in the baking soda solution can neutralize the acid that can be wicked into the strands of the wire. The neutralized acid/copper solution will be foamy and green. Subsequent dippings are warranted until the green mixture (copper sulphate) stops coming out. Rinse the area very well with fresh water and allow to dry. If acid leaked into the battery holder in the pour a mixture of baking soda and water on it to neutralize the acid that can eventually eat away the paint and supporting metal and rinse well. Prime an repaint the area if warranted. When reconnecting the clamps on the battery do not put the clamps all the way down so that they touch the face of the battery. Keep the bottom of the clamp up about 1/8" from the battery. This will keep future acid leaks from reaching the conector and reduce the likliehood of salts and the like from creating a current path on the surface of the battery case. (Yes, I know it’s only 12 volts) After you have reconnected the terminals of the battery you can apply a light film of lithium base grease to help keep moisture out of the connection and reduce the chance of a bad connection as well as corrosion. I hope it helps. – Hide quoted text — Show quoted text – > Original batt on a ‘94?

Response:
Thanks to the both of you that replied (and to anyone else that might reply before reading this). I tried to start it up again and it barely turned over after cranking for about 5 seconds, so I decided to get it checked. Diagnois: dead battery. They instaled a new one, cleaned up the connectors etc., and everything works fine again. Can anyone recommend a site or book or something that can tell someone with absolutely no car knowledge how to do basic maintenence and repair? Seems I’ve been having a lot of troubles with my Explorer lately and I don’t like being completely clueless. Thank you again. Mark

Put on some gloves and protective goggles. Disconnect both battery terminals, use a stiff brush or soft wire brush to clean the terminals and lead clamps, Protect the cleaned connections with some vaseline. Or, gGo to you nearest autoparts store and buy a battery terminal cleaner, use it and then protect the terminals with any one of the products the autoparts store will be happy to sell you. You should also put the battery on charge or have it charged. Battery chargers are relatively inexpensive and a useful things to keep around. Messing with acid is dangerous and you should not have to do it anyway. Hope this helps.
Response:
Don’t forget that the battery cables themselves (usually the positive one) can often be corroded inside the insulation, causing problems like yours. Replacig the bad cable fixes the problem. Also, of course, cleaning the terminals may do the trick. – Hide quoted text — Show quoted text ->Hi.

This is more of an alt.autos.non-specific <g> enquiry… In theory, yes. The condition of your battery (initial charge and general health) affects whether it is serious. For three weeks, I’d be wondering whether to disconnect the battery before laying up the car (although that will lead to other problems, of resetting things, when you reconnect; others will have to advise you there). Lead-acid cells tend to be damaged by being left discharged for long. BTW, don’t be tempted to leave the battery connected to a trickle charger during the lay-up. Not safe. — Andrew Stephenson
Response:
Without knowing the details, I would say no. If it was very cold, and your battery was old, then maybe.

Response:
I have a 2000 Olds Intrigue that sits in the driveway for weeks at a time in the winter, because I’m driving my Audis instead. Likewise, my Audis tend to sit around a lot in the summer. I also have an antique Cadillac that sits for long periods of time, though it has dual batteries and I disconnect them both when it goes into storage — so it probably doesn’t really count in this discussion. I’ve honestly never really kept close track of just how long each of these vehicles sits between being run, but I’d be willing to bet that every one of them has sat for more than three weeks at one time or another. And I’ve never had a problem with any of these cars’ batteries running down while parked. As long as your electrical system is functioning properly (no shorts or stuck-on seat warmers or interior lights, etc.) and your battery is in good shape, you should be able to let it sit for a good long time without concern of running down the battery. If your car’s battery won’t last three weeks, I’d be looking into it. Re The trickle-charger: Isn’t there such a thing as a "battery maintainer" that’s designed specifically to be left hooked up to Pb-acid batteries for extended periods of time? I’ve never used one myself, but I’ve heard of them and am would probably use one if a situation required it. That is, unless there’s some reason that I shouldn’t… – Greg Reed -1976 Cadillac Fleetwood 9-passenger sedan -1989 Audi 200 TQ Sedan -1990 Audi V8Q -2000 Oldsmobile Intrigue -2001 Chevy Astro AWD (wife’s)

That’s a reasonable list of provisos. How many of us can live up to them? ;-) When this came up last, I did back-of-envelope calculations, as follows (quotes from my 22nov2001 post to this NG): [...] For comparison (the only figure I have memorised), the Volvo 440’s factory alarm system draws a stated 27 mA when set. I have twice left such a vehicle parked for a month. First time, the battery was good and could start the car afterwards — just. Second time, the battery was crocked and afterwards could barely power the courtesy light. It had to be recharged before starting was possible. Soon after, it had to be replaced, as the sustained discharge state had finished it. [...] 27 mA for 21 days is a draw-down of 0.027*24*21 = 13.608 Amp-hrs. On the face of it, this is marginal cause for concern. OTOH: [...] a real-life battery rarely starts a parking period topped-up, especially if it is old and winter’s dark, cold days have been (a) diverting charging current then (b) impairing the battery’s ability to hold a charge. To that, add what starting the car then tries to pull out… Luck is going to be a big part of it. > Re The trickle-charger: Isn’t there such a thing as a "battery maintainer" > that’s designed specifically to be left hooked up to Pb-acid batteries for > extended periods of time?

I’m just wary of leaving mains-powered (er, that would be "line-" in the US, yes?) electrical stuff running if I am away for weeks at a time, especially if it feeds a potentially damp area exposed to physically active wildlife. Call me cautious. Also, so much after-market kit offered in UK motor accessory shops is of cheapo design and construction, begging to be allowed to start a fire in your car/garage/house and entertain the neighbours. — Andrew Stephenson
