I have a 2003 grand prix. The car will not start. Infact it wont crank at all and gets little or no power to the electronics of the vehicle. When key is turned to on position dash lights slowly fade on and...

You've got a good start measuring the voltage at the battery. Looks like you've got a low voltage problem. Common on the GM side post batteries is battery acid leaking at the positive battery cable post on the battery. I would recommend removing and checking the cables/posts on the battery. If everything is clean, reassemble the battery cables to the battery. If there is excessive wetness or corrosion on EITHER of the cables/posts, you should replace the battery first, and clean the cables. A leaking battery is going to give you more trouble down the road if you just clean it. If the battery connections on the existing battery are clean, charge the battery with a battery charger, or jump start the car. Use your trusty meter and measure voltage at the battery with the engine running. (Also do this if you replace the battery for leaks). You should read in the neighborhood of 13.5 - 14.0 volts if your charging system is working correctly. If you are reading in the low 12 volt range with the engine running, something is wrong with your charging system, and most likely putting a strain on the battery, preventing it from receiving the charge it needs. If your existing battery is not leaking, cables are clean and tight, jump starts okay, reads 13.5-14ish volts with the engine running, but refuses to crank the engine over after the engine runs for about 15-20 minutes, it's time for a new battery.

AA Battery leaked in my sony walkman cd player an now one of the posts has battery goop on it. What can I use to clean this off so I can put in a new battery?

First clean it with a dry soft cloth. Then you can use a damp cloth to wipe out the rest of the leaked liquid. You can use water or any water based glass cleaning liquid to damp the cloth as the leakage in alkaline in nature.

Hope it helps! Good Luck! Thanks for using Fixya!

No display for outside temp. after replacing batteries.

If the unit was workingg prior to the battery replacement, you must remove the battery and check on the terminals to the battery. Make that these are clean, the battery is good - test using a multimeter- and replace with the correct postion.
Now if the earlier battery had leaked it could have damaged the internal board and if so you need to open to check if the board is clogged with the battery leak. If so try and clean the board.

Do watch batteries leak?

And destroy the watch? Yes, but not as much as regular batteries do. The old alkaline batteries in flashlights are notorious for leaking, I have seen a couple times when the little batteries leak, One of my calculators leaked, but I caught it just in time. Cleaned up the contacts, and it works fine. If the battery did leak, send the whole watch and battery back to the manufacturer, they should replace it. Duracell has sent me a dozen flashlights and numerous battery coupons for leaking batteries. Hope this helps.

Coroted coppertop battery leaked on the termanals. how do i clean them

The battery leak can be cleaned using a solution of water and baking powder/bicarbonate of soda: dissolve a couple teaspoon in half a cup of water, dip a cotton ear buds/disposable napkins in mixture and use to help clean the corrosion from the terminals and then finally do the same with clean warm water(to neutralise bicard reaction) and dry wiith clean tissue. Hope it helps!

Batteries leaked, now it won't work

When batteries leak, that fluid can runn all around the inside nad in the wires and disolve the tiny connections on the circut boards. If the contact are really clean and shiney bright, and the flash won't work may be time to buy a new flash.

Batteries were left in the magic sing main microphone.

First, You should know that a leaking battery does not always mean any electronics the battery fluid has touched is ruined.  Quite often, depending on the severity of the leak, most battery fluid spills can be quickly and easily remedied with a few common household items, and maybe a trip to the electronics or hardware store.     Most alkaline batteries store their electrical charge in a chemical device, the battery cartridge.consumer electronics (AAA, AA, C, D, AND 9VOLT)  batteries are composed of alkaline electrolyte of potassium hydroxide and zinc powder and a chemical insulator between the two nodes.  Over time, alkaline batteries are prone to leaking potassium hydroxide, a caustic agent that can cause respiratory, eye and skin irritation.  When a battery leaks usually the cathode or + end with the raised button will leak the caustic potassium hydroxide fluid into the battery case of your microphone.  The battery fluid can cause a lack of conductivity on the battery terminals of your microphone and sometimes the circuitry also.     SOLUTION: First collect these items,   Rubber gloves.  The latex tight fitting type for protection from the caustic potassium hydroxide. Cotton swabs. You can use the small double ended cardboard type found in any drugstore or pharmacy.  A good electronics store will have long wood handled cleaning swabs (usually single-ended or one swab per wooden stick) if you need more reach inside to clean the compartment..  A small cup or can.  Warm water.  Baking soda. Paper towels or napkins. very fine sandpaper (400 grit or higher) or emery cloth.  dish soap. cotton swabs. an old toothbrush and clean , lint free rags. a blow dryer Open and disassemble the microphone as much as possible without disconnecting any soldered wires.  The idea here is to access ALL the surfaces of the mic so they can be cleaned of the caustic potassium hydroxide.  Make a nice solution of about one cup of warm water with one drop of dish soap add one tablespoon of baking soda. Stir well. With your gloves on, use the baking soda solution to clean the terminals and surrounding areas where the fluid has spilled. Use swabs, cotton and towels with the solution to clean the terminals, the surrounding areas and any circuit boards of the spilled fluid.  Do this as soon as you discover the problem, otherwise the powerful corrosive effects of the fluid will cause iron and zinc oxides (rust) to form and these will require a more aggressive approach, namely abrasives. If there are any rust like deposits left after cleaning with the baking soda wash use the blow dryer to completely dry everything.   Sanding should be kept to a minimum but is sometimes "a necessary evil".  The idea is to clean the nickel chrome battery terminals and NOT remove their nickel chrome from the spring-steel battery holder/terminals.  You want to clean the terminals, not remove so much material that the conductive plating is also removed or the battery doesn't fit because the gap filled by the battery is enlarged.  You just want to clean the chrome surface of the battery terminals of your device.  Make sure the unit is clean and completely dry before installing new batteries.  re-assemble your device if necessary, load new batteries and power up!    This is a common repair for any unit which has been stored with old batteries, or if exposed to prolonged heat  or humidity. Store all battery powered devices, especially transmitters, or remote controls in a cool, dry, place, removing battteries if stored over 6 weeks.    If this solution provides no repair, it would be reccommended to seek the Manufacturer's authorized repair center nearest you, or just replace the unit.

Battery leaked

Try a solution of baking soda and water. apply it to where the battery leaked and try to clean it that way. after you clean it you might want to get a can of contact cleaner and aspray on all the terminals. You can get this at radio shack. I hope this helps you.

RCA wireless headphones WPH141 Batteries leaking

Good Quality new batteries will not leak.
Excessive heat might cause a battery to leak.
Batteries should not be stored in a place that will expose them to high temperatures. The same would be true for wireless headphones with batteries in them. The dashboard of a car would be a very bad place. Shelf life of batteries is limited. New batteries and low temperatures should help.
