How to recondition batteries depend a lot on what kind of battery it is. For example, it can be Lead acid, or simple Li-ion battery. Correct knowledge of chemicals and proper handling is necessary for safe reconditioning of batteries.
A question Sir! Why its is necessary that we must use a cell of same chemistry, we are just dealing with voltage and current. Why the chemistry matters?
How to Get Your iPhone's Battery Replaced at Apple Store or Apple Authorized Service Provider
If your old battery is from NAPA, you can take it to a NAPA store, along with your invoice, to have it recycled. You’ll also receive a store credit for the amount of your core charge deposit. Installing the New Battery
I have Lenovo G50-70 but I was replacing the screen en I forgot the battery in the laptop now when plugged in power it charges up to 6% and when you unplug from power the machine goes off completely
You do not need to pay anything until your iPhone is repaired and back in your hands. Once you get it back, you can pay either by cash, card, UPI, Wallet, Online or Bank Transfer, whatever is comfortable and convenient to you.
2, there is another way that to remove the battery, put it for about a week, the electricity will be slowly consumed, you need to use the machine to completely consume the electricity. Then fully recharge, it is estimated that your current charging time must be very short, after the full, disconnected and recharged, repeated several times, absolutely effective.
My laptop said consider replacing your battery.but the output volt of each cell has good .what I do? Pls help me...
You didn’t leave a car door open or a light on. (We believe you.) But your vehicle just won’t start. You turn on the ignition, and all you get is the telltale clicking noise. Possibly followed by competing pronouncements of “Your battery’s dead” and “It’s your alternator” from anyone within earshot.
Another thing you can do to drastically extend the health of a lithium-ion battery is to never fully charge or discharge it. If you charge your battery pack to 4 volts per cell and stop using it when it reaches around 2.8 volts per cell, then your battery pack will have a lifespan that is 2 to 3 times longer while having a capacity only around 20 percent less. You can build a lithium battery charger to customize the charge current and voltage.
ThanQ Very much and happy to see such an article, which gives immense idea to rebuilt a laptop batteries to every electronic hobbyist
The iPhone provides us with many services. We can work from our phones by sending emails, joining work calls, and more. Outside of work, we text or facetime our friends, order dinner, and check our social media. Over time, your battery may start to show signs of needing an iPhone 6 or iPhone 7 battery replacement. If you are considering taking your iPhone to a professional for battery replacement, you might be wondering if the process will affect your phone’s data.
Note: Sometimes, you might see insights into usage patterns and conditions that cause your device to consume energy. There may also be suggestions to help lower your energy consumption.
Step 4a: There is a chance that you can simply charge any low cell groups that you find to bring it up to balance with the others. The good news is that you don't have to break down the battery to find out. This may be all you need to do to fix a broken battery.
Notably, Apple opened up its self-service program for U.S.-based iPhone users last April, which allows people to get and replace parts without any external help.
