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!

Usually, the 12 V car battery are Lead acid based with Lead terminals and Sulphuric acid as the electrolyte for the battery construction. We know about two types of car batteries-Flooded cell (Wet cell) and Sealed cell (Dry cell).
When your car battery fails, you won’t be able to start your engine. Usually, dead car batteries may be revived – at least temporarily – to get you back on the road. However, the accumulation of damage may lead to an untimely demise of your car battery, and this typically needs to be replaced.

Risky? A little. But people don't seem to think twice about throwing their kids in a Tesla that has 7,200 of these exact same batteries that were all just supercharged from dead to past nominal voltage in 20 minutes flat. This is only 5. Still, wear acid splash goggles, have a respirator ready, and maybe something fire resistant.
The second method for charging a car battery is to use jumper cables to connect the dead batter to a running one. Most drivers are already familiar with jumper cables, but not everyone is sure how to use them properly to connect two cars. Here, is a step-by-step guide.

iPhones come with Li-On (Lithium Ion) Batteries and their performance is measured not how big the Li-On cell is but its capacity that is measured by mAh (milliampere per hour). Although all iPhone models till date have 3.8V battery but Apple has provided different mAh for different models based on their architecture, form factor (size, design) as well as performance parameters. iPhone 6, iPhone 6S, iPhone 7 and iPhone 8 all have more or less ~ 2000 mAh batteries. However, iPhone X, iPhone XR, iPhone 11, have higher mAh battery i.e. ~ 3000 mAh. iPhone 11 Pro Max and iPhone 12 Pro Max have highest mAh, which is almost 3900.

Desulfation is quite a tedious and time-consuming process, but worth every second given its effectiveness. Desulfation is not as complex as it is made out to be. Firstly, you should remove the Lead sulfate build up. Next, clean the deposits with the help of Magnesium Sulfate or Epsom Salt. With Epsom Salt, distilled water and a regular Lead acid battery charger, you are ready! But for safety purposes, please ensure to put on protective gloves and eyewear. Take some clean and dry Epsom Salt into a dry cup. For an averaged sized battery, measure about 10 tablespoons of Epsom Salt. The distilled water should be heated up to temperature around boiling point. Add distilled water to Epsom salt to forma thick liquid and stir it properly to dissolve Epsom Salt well. Pour the mixture of distilled water and Epsom salt into every battery cell battery as much as possible. Plug in your charger after having the battery covered and set the charger for High Amps (high current). It is advisable not to use smart charger for more readable meter. Meter only shows two possibilities-“zero” or “charged”. Depending on the extent of sulfation, the entire process might take some time. Next, switch it over to low current and keep it charging until it is full. Once the battery is fully charged, discharge it and charge it again. The current should be low this time. Charging on low current enables the Epsom Salt to break sown the lead sulfate deposits on the battery. When you charge it on the second try, it is finally ready to soar! You can repeat the desulfation process for maximum five times on any battery which can extend its lifespan by years.
Many times, there are apps that are not updated even if “auto update” feature is turned on. So, keep on checking for any pending updates of your apps that you mostly use and update them manually. In cases you are not using some of the apps frequently or for that matter haven’t even opened it since last 3 months, we suggest you either delete the app OR put them in “offline” mode.
One day, the life of every battery will come to an end. But what options do you have if your e-bike battery suddenly drops?

Reconditioned car batteries are the procedure of restoring the life and charging capacity of the worn out battery. You shouldn’t throw out your old or dead cells as you can recondition them for 1 or 3 times.
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.
In this article, I will focus solely on the 12-volt lead-acid battery that’s located in most gas and diesel vehicles. When one dies, a jump start might be necessary. However, you can prevent this by reconditioning your car battery. With a few simple steps, you save yourself a trip to the auto parts store and avoid costly battery replacement.
Please direct marriage proposals to my publicist. A certain tool company is *not* interested in proposing marriage to me. So I'd like to make a point of saying I love these tools and use them all the time. Their batteries and chargers on the other hand, could use some improvement.
You might be asking how often should I get my battery checked? We recommend a regular annual inspection to catch the problem before it occurs. Also, remember that the average life expectancy of a battery is 3 to 5 years.

Put the plastic cover back on the battery pack (just the part that goes into the charger) and set your battery on the charger to see if it will take a charge. If you still only get a red flashing light and the battery won't charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.
I didn't shoot a video, but with power meter you can watch the current pulse. The battery will take 0.5A for a second or two, then 0.7A for another second or two, and then back to 0.5A. And as the charging process progresses the amperage levels increase gradually, but always pulsing.
It’s good to know that you can’t recharge your car battery by letting it run if it is below 12 volts. I would like to get my car battery tested this month to see how it is performing. It’s an old battery, so I want to make sure that it’s still up to par. https://southsideservicecenter.com/
i have compaq 610. issue is ,it notifies that charger is plugged in,but it does not charge .also, every time i plug out charger,laptop turns off without saving session.
Yes. A battery pack contains many battery cells. Not all of them are going to be bad. Depending on the battery pack's construction, it can range anywhere from extremely easy to excruciatingly difficult to open the battery and remove the bad cells. As long as you can identify the bad cells and remove them from the battery pack, you will be able to repair the battery. It also may be as simple as balancing the series groups that are out of balance from the rest of the pack. It could even be as simple as the BMS went into safe mode and needs to be woken up.
Flooded cells have detachable caps for each cell where distilled water is filled up to the working level. Although it lasts for about 4-5 years, it is quite sensitive and requires constant maintenance (every four months or so) to check and maintain water levels in the cell. It is the older version among two.

Adding distilled water may help submerge the plates and enable more reaction to help give the engine a few more turns. This will help if the problem is due to low electrolyte levels. Using distilled water only as an electrolyte booster is an alternative if you don’t have an Epsom salt or aspirin available.
Super quick and reliable service. The customer rep was kind, and very patient in answering all of my questions given the back of my iPhone was shattered quite badly. He wasn’t trying to up-sell me or anything. Straight and honest advice which I appreciate. I will definitely be coming back and recommending this store to my family and friends. It was done within 2 hrs as well while other stores I checked in with said my phone would have to be there overnight. A+++ service! Thanks team!!!

Visitors of BatteryUniversity.com frequently ask: “Can NiCd can be replaced with NiMH?” In theory, this should be possible as both chemistries have the same cell voltage, but full-charge detection and trickle charge are the issues. NiMH uses a more refined charge algorithm than NiCd(See BU-408: Charging Nickel-metal-hydride) A modern NiMH charger can charge both NiMH and NiCd; the old NiCd charger could overcharge NiMH by not properly detecting the full-charge state and applying a trickle charge that is too high. Each chemistry requires its own charger.
