My new laptop was normally used only for several days and then not used for few months and now it's li-ion battery is totally discharged. I have plugged power source even for 12 hours, but unfortunately it is still 0 % :-(. My battery data: 4ICR19/66 L12M4E01 14,88V 41Wh 2800 mAh Is there any way to bring it back to life? Is it possible to self discharge smart battery "to death"? Thanks for your help
The charging control electronics BMS is disabled, if you recharge the cells, the repair works. An example is the hoverboard accumulator, for which there are several videos on YouTube. look at them and you will understand too.

5.0 out of 5 stars No more getting gouged by the watch repairman! I'm very happy with this kit! It has much more in it than I will ever use but that's okay. I purchased it after paying a criminal amount to have a battery put in my watch. I could have purchased the battery for a fifth of the price, and put it in myself. I needed the tools. This is just the thing! I've told everyone that I have it so don't pay someone to change your watch batteries anymore! Just buy the battery for a few dollars. It's a perfect entry level for the home watch repair for doing straps/bracelet stuff or battery changes. It's a quick/ inexpensive kit for he person who wants to get into watch mods.

Do not disregard this as not needing a replacement. Throttling is merely a preventative measure that temporarily impacts performance, so getting your battery replaced is still strongly suggested. Waiting could mean having to purchase a whole new device.
Always replace batteries in a device as a set. That is, if a device requires four AA batteries, replace them all at once because one low battery can drain the others or still not power the device. You can mix brands, but not battery types such as alkaline and dry cell. Never mix sizes (AA and AAA, for example).
You need the right battery for your vehicle, and going with a Toyota means that it was specifically designed and engineered to match your vehicle’s specifications, in size, voltage, terminal configurations, and with your Toyota’s electrical and charging systems.
The 18-volt drill battery method works like a jump start method. To do this, you need a fully charged 18-volt drill battery and jump leads. You can buy these from auto shops. Using the jump leads or other adaptations, you need to makeshift the connection between your dead car battery to the 18-volt drill battery. This allows the drill battery to connect to the dead battery like a standard jump start method.

If you are operating your battery packs in extreme temperatures, that places a high level of wear on the battery cells. This may not seem like something that happens that often until you realize just how hot it can get in a car with the windows up during summer.
All in all for battery maintenance it'll get the job done......now will it last? seems to work well, charged up my battery and will check level of battery even when not plugged in Bon produit, il charge bien les batteries, sauf qu'on aurait apprécié un câble reliant la batterie un peu plus long.
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.
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
