I have just brought a new charger for my Toshiba laptop to replace an old one that had a wire exposed and damaged. The new charger is supplying the correct voltage and turns my computer on and displays 0% available (plugged in,not charging) Is there power surge protectors installed to avoid damaging your battery or computer hardware on toshiba laptops? Could the damaged wire have caused a problem with the battery or with my laptop itself ?

In a battery pack, several cell groups are welded together + to -. Because of this, it may seem like there is no way to charge one of the cell groups individually. You can, though. All you have to do is solder a wire to the positive end of the cell group and another to the negative end. You can connect these to wires to a constant current buck converter set to 4.2 volts.
2) They discharge even when they're sitting on the shelf doing nothing. If you run you're drill to the point where it says stop I'm gonna die forever if you keep using me, and then you just throw it in a box, it still keeps discharging. Very soon it will be useless.

If you fill a battery with more energy than it's designed to take, then you will do a small amount of permanent damage to the battery. Over time, this damage adds up and it can lead to overheating and thermal runaway.
Make sure that you use NiCd batteries with a typical capacity between 450mAh and 800mAh.
I re-celled a laptop battery with 4 cells. After completion, I turned on the laptop but it didn't power up! The laptop does turn on with AC Adapter plugged in, but if I unplug the charger, the laptop shuts down, as if the the battery has been removed. System (Windows 8) shows that the battery has been charged [Plugged in, charging 100%] but the battery doesn't power the laptop! Why? Help!

Thanks!!!!!!
Afterwards, put the charger away and note readings from the voltmeter. The reading should be 12.4-volt. If you want, you can have a battery load test.
Next, select the iPhone to be serviced, select Battery, Power, and Charging, and finally select Battery Replacement. Next, select Bring in for Repair and specify your location and carrier.
The problem is that the iPhone Pro models are more appealing to consumers, with only a $200 price difference between the existing iPhone 14 Plus and iPhone 14 Pro Max. Both phones have the same screen size, but the Pro Max offers the latest A16 chip, a ProMotion display, a telephoto camera and a stainless-steel design.

A battery shop may salvage good cells from a failed pack for reuse but the recovered cell should be checked for capacity, internal resistance and self-discharge – the three key health indicators of a battery. When checking a cell with a battery analyzer, mark the capacity so it can be matched with a pack that may need a cell of similar capacity level. Also make certain that the internal resistance is in par with a good cell and verify the self-discharge. Electro-mechanical stress often manifests itself in elevated self-discharge. To check self-discharge, fully charge the cell, measure the voltage and compare the voltage after 24 hours and perhaps a week with the voltage drop of known good cells.
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
