To clean acid leaks you use baking soda or sodium bi-carbonate in water solution then clean of with fresh water
vinegar is an acid and acid will not neutralize acid so it will come back when dry
as for the rest it is possible that the soldered joints for the wires are affected and may have to be resoldered or the copper in the wires has also corroded away.

I hardly drive my car so ive disconnected the battery,car havent been driven for over 6mths now, reconnected battery but no click & no start plus alarm doesn't work either. Pls help

Ultimately you will need a new battery.
Inthe short term, pry off the small covers and ensure there is enough acid solution to cover plates inside... Not completely full, about 3/8" down.
Then once all ok on fluid (add water if low), charge battey for a while or get a jump start. AAA is your friend for this.
Battery will not live long after being completely discharged but this may give you a little time

Problems with right side gauges not working in a 1986 bmw 325.

if your rpm gauge temp gauge and your odometer stop working in your 1986 bmw 325 check the sid batteries located inside the instrument cluster. chances are those are blown up. checked mine today and they were covered in battery acid. i replaced them with new ones and everything works now. tip they need to be rechargeable batteries. The altenator recharges them as the car is on.

Any reason I cant take battery from junk 92 buick + put in 92 chev S 10 ?

Good morning Doug.
The batteries may well look the same, and you did the right thing to compare the Cold Cranking Amps (CCA) to see they are about the same. From a form and function standpoint, it may well work.

The think you want to be careful about is how old the Buick is. Hopefully not the original. Even if treated nicely, a 23 year old battery is a stranded-at-roadside waiting to happen. Even maintenance free batteries will lose water and acid. If it's more than half the age of the Buick and S10, I'd use it only as a stopgap.
That said, if you do move it, most any battery shop will do a free battery test for you, which will help you tell if it's still working OK. I'd also take the opportunity to thoroughly clean the battery cavity in the S10, brush off or repalce the battery terminals, and give the battery a soda bath to clear any acid that has vented to the surface. To do this, make a paste of baking soda and a pit of water, and, with gloves, on, spread it over the top of the battery. If there's any bubbling, the soda is neutralizing leaked battery acid. If it's an old style battery with removable water-fill plugs, be careful not to get soda into the battery itself. Also, if it has such plugs, carefully remove them and see if the liquid inside is covering the battery elements (they'll look like thin plates standing on edge. If uncovered, carefully pour enough distilled (not tap, not filtered. distilled) water in to cover the plates and replace the caps.

once the soda bath stops fizzing, rinse the soda off and dry the battery. if you have a charger, charge it first, then install it.

Good luck, and be safe around the acid. If you replace with a new one, please make sure the old battery is recycled - they're full of lead and a horror for the environment if just dumped.

My batteries were corroded so I took them out ,cleaned it up the best I could, put new batteries back in but it doesn't work. What can I do?

The battery acid has caused further damage! Take apart and clean might be able to save it!

Problems with X6 5.0 2010 accumulator battery. After week of non-driving the battery completely empty. At BMW service told me that the battery is Ok, its normal(!!!!!!!!) for X6.

It is not normal on any car.
A week is too long for a major current drain, so it has to be something small. A small courtesy light bulb in a storage compartment that is failing to turn off?
Have you added any audio accessories? (amps, DVD players, etc) Sometimes aftermarket accessories have nasty drains and have to be unplugged when the car will be parked for an extended period (months) but if one is draining your battery in a week, it is defective.
The last suspect is computers. This car has multiple computers on it that are supposed to go into sleep mode a few minutes after you shut off the car. Perhaps one of them is not going to sleep? That would not be as tough to diagnose as you might think. You put an ammeter in line with the battery and watch the current flow. It will be high at first, and then drop off after 5 minutes or so. If it is more than 50 mA or so, it is too much, so you start pulling fuses and disconnecting things until the current drain drops down below 50 mA.
On a 2010 X6, you are probably going to have to reprogram a lot of stuff after disconnecting the battery to diagnose this problem.

My batter want stay chareg an i got a new alternater

batterys generaly consist of 4 cells if one cell goes bad usually the battery will function but not at top preformance some batterys are sealed by the manufacture so you cant service them others have a plastic removable square plug which plugs two of the 4 cells very carefully remove one of the plastic covers from the battery remember sulferic acid burns a lot.... if one of the cells in the battery is dry add water or if you are a mechanic you can purchase acid in a plastic container at any auto parts suppier if the battery doesnt put out at least twelve volts i recomend replacing it servicing batterys should be handled with extreme care any they range from 40 to 140 dollars buying a new one may be the safest ansewer

Car won't start after battery was cleaned.

what do mean the battery was cleaned ? was the fluids inside removed ?

or was the terminals (where the cables connect) cleaned due to some whitish build up ?

If the fluids inside were cleaned you can try (and this will probably not work). remove the battery from the car.

open the battery (the caps where the water goes in). remove the fluid inside (be careful it may be sulfuric acid) then rinse out the battery a couple of times with hot water.

leave battery in sun with caps off to dry out completely.

fill the battery with battery acid.

Put the battery on a trickle battery charger for 24 hours or until charger indicates full charge.

Reinsert into car and connect the terminals.

See if it worked.

If it didnt -> replace the battery

If the terminal were simply cleaned, lossen the terminals with the correct spanner, pour some hot water over the terminals to wash away any residues, then while the terminal are still wet fasten the terminals once again.

Remember that should the fluid inside your battery gets low (should be checked regularly) fill it with battery water (distilled water) only.

Smell of rotten eggs, and smoke coming from under neath the battery on the drivers side.

Disconnect the battery and remove it...WEAR PROTECTIVE CLOTHING!! The battery sounds like it is leaking acid and, as such, needs to be replaced ASAP! Once you pull the battery out of the car, only set it down on a surface that will not erode from the acid. If the battery is indeed leaking, you will see the corrosion where the battery was eating away the metal. This will need to be cleaned and neutralized before anything else can happen, if the battery is leaking.

I do think your battery is leaking; sulfuric acid smells like rotten eggs and the smoke is from the acid eating the metal it is coming into contact with.

My battery boiled over

If the needle on your gauge 'move as if the alternator is cycling on and off.' you should have your charging system checked. Also, if the battery 'boiled over' you should get a box of baking soda, make a gooey mix w/ water and pour it all around the battery. This will neutralize the acid, which will corrode everything it comes in contact with. After the foaming stops when u treat the area w/ the mix, flush with clean water. countrycurt0
