Can a battery read 12v and still be bad?
Cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell.

Does Epsom salt restore batteries?
Epsom Salts Restores Lead Acid Battery. Despite a lot of advances in battery technology, lead acid batteries are still used in many applications due to cost and their ability to provide a lot of surge current. But they don’t last forever. … Obviously, epsom salt can’t repair damaged plates or do any other magic cure.
How long does it take to Desulfate battery?
48 hoursDepending on the size of the battery, the desulfation process can take from 48 hours to weeks to complete. During this period the battery is also trickle charged to continue reducing the amount of lead sulfur in solution.
How does a battery Desulfator work?
A desulfator uses voltage or high-frequency pulses to “zap” the sulfates that have built up over time in your battery. The electricity loosens the sulfates and they drop back into the acid and dissipate. A good desulfator can rejuvenate your batteries and save you money over the long run.
How long can a car sit before the battery dies?
This article was published more than 7 years ago. Some information in it may no longer be current. A car should be able to sit parked for at least a month without the battery dying, unless it’s a higher-end car with plenty of power-hungry gadgets and computers, experts say.
How do you revive a dead car battery with aspirin?
Crush two or three aspirin tablets for each cell of the battery and carefully put the powder in the battery. Now add water to fill the battery to the proper level. Carefully reseal the cell cover. Let the battery sit for almost one hour before you start the engine.
Can you revive a dead car battery?
Usually, a jump start, booster pack, or battery charger is all that’s necessary to revive the car battery and get the car back on the road, but the damage has already been done. … If the car battery is left discharged for long periods of time, “hard” sulfation occurs, the formation of lead sulfate crystals.
What does Desulfating a battery mean?
The lead sulfate crystals are broken down (more or less successfully) in the charge cycle. Sometimes some crystals remain, or sometimes a battery is left partially discharged where the crystals of lead sulfate harden, and reduce the capacity of the battery to be charged. This is what desulfation (desulphation)is about.
Can you put vinegar in a car battery?
Do NOT use vinegar in a car battery. It is acetic acid and will react with the sulfuric acid in the battery and the lead terminals to form lead acetate. Not good. Only use distilled water for small amounts.
Should I add water or acid to my battery?
It’s important to note that battery owners should never add sulfuric acid to their battery. During normal operation batteries will only consume water – and not sulfuric acid. When your battery’s electrolyte is observed to be low, filling the battery with water will keep the battery healthy and safe for use.
Can a completely dead battery be recharged?
While your vehicle’s alternator can keep a healthy battery charged, it was never designed to completely recharge a dead car battery. … These charging devices are designed to safely restore a dead battery to full charge. Most of the time, you don’t even have to remove the battery from your vehicle.
What does Epsom salt do to a battery?
These salts may reduce the internal resistance to give a sulfated battery a few extra months of life. Suitable additives are magnesium sulfate (Epsom salt), caustic soda and EDTA (EDTA is a crystalline acid used in industry). When using Epsom salt, follow these easy steps to treat most starter batteries.
