Step 2: Make sure there are no cracks in the conductor and no burn marks on the cells. Also, make sure there is no liquid coming from anywhere.
My sony vaio model number VPCEA33EN is showing the battery message as ‘Unknown remaining’. It is not getting charged and as soon as i remove the charger the laptop shuts off. I called up the service center and they said that they can replace it but will cost like 150$ or Rs. 8000 Can the battery be repaired ? Please tell me what to do as i can’t spend that much amount to buy a new battery.

go to a technician he will sold the battery terminal with the broken pin area with a wire
The first thing you need to do is inspect the physical appearance of your battery for signs of damage. Always wear gloves when doing this.
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!!!
I use an ASUS F200 LA computer. The battery was not charging. When plugged in, it will display charging, but it won't leave 0%, and it switches off immediately when it is not on an external source of power, so an engineer helped me in boosting it by charging it through its positive and negative terminals after loosing the battery, then it charged to 58%, but it will still not increase when charged with the laptops charger, and when the power adapter is unplugged, it switches off immediately. Please what can u do.
This process is eco-friendly too because batteries are difficult to recycle. So, if you are tempted by now to consider bringing life back to your good ol’ battery, see the following guide.

Frequently Asked Questions There are multiple issues with my iPhone, can I get some discount if I get it repaired from you?
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.

Cells designed for a multi-cell pack require tighter tolerances than those destined for single-cell use, such as a mobile phone. Cell manufacturers cannot fully control the capacity and hence some have higher capacities than others. In a single-cell device the average consumer does not notice such a variance. Quality cells for a multi-cell pack, on the other hand, are capacity-matched, lest they fail.
The second rating, which is always higher than the first one, is called the burst or max current rating. This rating is a little more difficult to understand as it involves a timeframe. Not all cell spec sheets and battery cell manufacturers rate burst current the same way.

If you charge your battery faster than what it is rated for, it will damage the cells and increase their internal resistance. A higher internal resistance produces more of a voltage drop which hurts performance. Also, a higher resistance makes a battery produce more heat for a given charge and discharge current.

I unplugged the charger and took a reading with the multi-meter: the battery was producing 13.16 VDC. An hour later with the clamps still on, the 13.04 VDC.
