If battery doesn't hold the charge then it is considered dead. Dead batteries seem to be charging to even 100% but they don't have power to keep laptop powered on. What does show DESIGN CAPACITY, FULL CHARGE CAPACITY in batteryhealth.html from Desktop, if you run this command in Win10? powercfg.exe -batteryreport /output %userprofile%/Desktop/batteryhealth.html >>abhi wrote: Please help I have Lenovo z510 battery as written in article there is switch which doesn't let power to terminals. You could boost each cell directly with 5V a little bit(30sec) so laptop can charge it again,
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.

Repeat the "pulse" boosting and testing the battery until it will finally be recognized by the charger and you get the green light. Black wire = negative Striped or solid white wire = positive It is very important to not mix the two up. There's a hidden screw under a piece of plastic. You need to pry the plastic off to get at the screw underneath. I used a very thin screwdriver to pry it off. Volts are symbolized by a "V" with one or two straight lines over it on a multimeter so it's that section of the multimeter that you use. The section under the V with the straight line(s). Not the squiggly line. The straight line. Lithium ion batteries need to be "pulse" charged. Which means you hold your wires down for 15 seconds or so, then release them. Then hold them down again. Over and over.
Just keep repeating the "pulse" boosting and testing the battery until it will finally be recognized by the charger and you get the green light.

Description: These are compulsory for your safety when you deal with Lead acid batteries. The acid in batteries are extremely painful and corrosive if it ever enters your eyes.
Swelling is actually a safety mechanism as it prevents the battery from exploding. It's important to keep in mind, however, that if a lithium polymer cell is designed and used in the proper way, it won't reach the conditions required for it to begin swelling.
