Thank YOU for your great post on how to recondition old batteries, I think it is the most efficient way to recover old batteries instead of just buying new ones once one gets damaged. I personally am using the recondition methods instead of buying new ones, and find this video on the internet which I hope will helps somebody.
For the rest of you? I know exactly how you feel. I felt the same way. Let me know exactly how elated you were after you brought your first battery back to life in the comments section.
Wearing gloves and eye goggles for protection, mix 2 tablespoons of baking soda into 1 quart of water and stir well. Dip a paintbrush into this mixture and liberally paint onto all areas where there is corrosion on the battery, especially on and around the battery terminals. Expect the mixture to bubble and fizz where the baking soda and battery acid come in contact with each other.

If you don’t utilize the batteries for some weeks or more than that, put them on a trickle charger in order to preserve performance. The stored battery slowly loses its charge which leads to the buildup of sulfur on the lead plates.

Fortunately, our batteries tend to last an exceptionally long time. That’s because we use the latest absorbent glass mat technology in all of our products, which makes them less susceptible to sulfation and leaks.

Swollen Battery is a pretty dangerous symptom and it should be treated immediately to prevent any further damage to iPhone and its other components such as Display. Typically, we have experienced from our customers that this happens if your iPhone is water damaged but several other reasons such as overcharging (overnight charging), using non-genuine (non MFI) charging cables or adaptors and / or the battery was replaced earlier with aftermarket quality.

If you have Magnesium sulfate (commonly known as Epsom salt) with you can easily recondition a car battery. First step is to check the battery voltage and ensure it to be less than 12 V. This shows that it is already dead. Heat about half a liter of distilled water to about 333K-348K (about 30 K below the boiling point of the water) Now, mix about a quarter of Epsom Salt in heated distilled water and stir it until the salt dissolves. For two different types of cells, this step involves different procedures.For flooded cells, you need to remove the battery cell cap.For dry cells, please drill through the sealed cap.For both the cells, pour out the old electrolyte. Insert the new electrolyte into the cell with the help of a funnel. (mainly Epsom salt + water) Next, for a flooded cell, replace the battery cap. For a sealed cell battery, plug the hole in this step. Keep in mind that you have to keep electrolyte properly distributed with no hint of air bubbles inside the cell. Finally, charge it slowly by keeping it on trickle charge overnight and then let it cool. By morning, you have a reformed cell in your hand that performs as good as new!

3) The batteries don't like to sit at 100%. Once it's charged, take it off the charger. Bonus points if you put it right into a tool and turn it on for like 5 seconds. Now it's at like 95% charge, it's much happier, battery is now ready for storage and doesn't need to be touched for a year.

The battery is not failed, it’s faulty/badly manufactured. It’s heavily documented as well that this is a common reoccurrence with these sort of batteries. And it DOES WORK I JUST DID IT 😀
If your vehicle won’t start with a fully-charged and healthy battery, the usual suspects are problems with your starter, your alternator, your ignition switch, your spark plugs or your fuses. It’s also worthwhile to clean your battery terminals and connectors if they’re dirty or corroded and see if your car will start. But the only way to be sure your battery is healthy is to test it with a voltmeter. When you have your vehicle towed to Midas, it’s the first thing we’ll check.
First, clear the corrosion. Make your own cleaning solution by mixing 2 teaspoons of baking soda and 1 spoon of water. With a toothbrush, rub the cleaning paste on the terminals. If corrosion is heavy, get a steel wool.
If the battery reads below 12 volts, it’s considered “discharged.” Driving around can’t revive a battery below 12 volts, and attempting to do so might damage the alternator.
Using a lithium-ion battery beyond its sustained rated current will cause damage to the cell. Lithium-ion batteries essentially have 2 current ratings. The first rating is related to how much current a cell can provide continuously. Continuous current is pretty easy to understand because it's simply the amount of current that should not be exceeded. For example, it's easy to stay under 25 amps when you can see how much current is being used on a meter.
It'll work. But while you celebrate your successful your battery is very quickly dying again. Capacity will never be the same. Your 2Ah battery is now a 0.5Ah if you're lucky

Small household batteries (AA, AAA, C, D) are also called “dry” batteries because the electrolyte is a paste of powdered chemicals. Alkaline batteries use an alkaline electrolyte. A battery’s voltage depends on the metals that are used in its electrodes and the number of cells. Household batteries produce 1.5 or 9 volts of direct current (DC) electricity, depending on the model.

Select the proper setting to fit the type of charge depending on the type of battery in your car and the speed of the charge needed. Usually there is a setting to charge 6V batteries, as well as fast and slow charging rates for 12V batteries. If you see a ‘crank assist’ setting, this is for simply jump starting the battery.

You must complete these steps in order. If you disconnect the positive terminal first, you risk short-circuiting the battery and damaging the electric component of your car.
If you want your battery pack to last as long as possible, then avoid extreme temperatures and high levels of heat and humidity as those things are bad electronics in general. Also, do not leave your lithium-ion powered devices and battery packs in a hot car.
Before beginning, if haven’t already, considering getting yourself a handy OBD scanner which allows you to connect to car after battery reconditioning, and instantly detect any faults within the OBD software.
Step 4B: eBike batteries are generally pretty high current, so BMS failure is more common in these types of batteries. If you get lucky and see a burn mark on the BMS, then you can more than likely just replace that part and your battery will be good to go.
Mix 8 ounces of Epsom salts into 2 quarts of warm distilled water. Stir thoroughly. Use your turkey baster to fill each battery cell with the Epsom salts solution until the cells are completely covered.

Measure the voltage of a repaired pack and check it again after 24 hours and a few days. If a cell drops lower than another in the pack, then there is fear of elevated self-discharge(See BU-802b: Elevated Self-discharge) Simple Guidelines when Repairing Battery Packs Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.Include a temperature sensor that disrupts the current should the pack get hot.Apply a slow charge to a repaired pack to bring all cells to parity.Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.Check a repaired pack for self-discharge. Intrinsic defects often reveal themselves in an elevated self-discharge. Previous Article Next Article
Thing they don't mention tho is that even if your jump is successful the capacity of the battery will forever be trash. You'll be lucky if you 2Ah battery is now a 0.5Ah. might a couple minutes out of your reanimated battery pack before it has to go back on the charger.
What’s the most important factor in buying replacement batteries? Expiration date! Dollar for dollar, alkaline batteries with a distant expiration date (fresher battery) will give greater value than an expensive battery that will expire sooner. Check the side of the battery to determine its DCvoltage. Commonly, AA, AAA, C, and D are 1.5 V, and rectangular batteries are 9V. Set the multimeter to the VDC (volts of direct current) scale. Touch the red multimeter probe to the battery’s [+] terminal and the black probe to the [-] terminal. If the reading is more than 10 percent below the rated output (1.35 V or 8.1 V), the battery is bad and should be replaced.
