SIR, My laptop ASUS X540S, three month ago his battery had a cell from three damaged and I continued to use it like that. The battery has 3 cells, the middle one had 0V, the two others had 3.88V and I replaced the damaged with a new one. Unfortunately now the battery seems disconnected from the charger. I see 13% available (plugged in, charging), but battery do not charge. When disconnected, the 3-d terminal shows 3,2V, the 8 others 0V. When charger is connected : terminals 1 and 2 have 0,06V, 3 have 3,2V, 4 0V, 5 and 6 have 3,25V, terminals 7,8 and 9 have 0V. When system started, nothing change. My question, which terminal is the switch one ? If I connect to ground through 100 ohms any terminal, do I risk to damage the computer ? What should I do ?
I need Vaio E series laptop charger circuit, which has 220v I/P and 19.5V O/P wtih 3.9A at 50-60 HZ....

Wipe all surfaces of your batteries with plain water until you have cleaned away all of the corrosion.
A car battery should be replaced when its capacity has dropped below 12 volts -- which happens to most batteries after three to seven years of use. Here are some signs that your battery is running critically low:
Charged your iPhone all night just to see not lasting til lunch time? Then you definitely need an iPhone 6s battery replacement or an iPhone 6s battery repair. We are located in Regina and can provide the services for any repairs involving iPhone batteries. We will do a quick and replace your battery with a highest quality battery out in the market.
But before we shall continue, it is important to know the differences between reconditioning and recharging. Reconditioning a battery means restoring battery back to its full capacity (it is as good as new!) while recharging simply means putting in charge for a period.
We not only carry batteries but we also have the accessories required to power your electronic devices – battery chargers, cables, and inverters too. We know Christmas is going to look a little different for a lot of us this year but
How to choose properly: make sure output voltage not be any lower than 9V, and the wire section not to be any less than 16 sq. mm.
But as the saying goes, prevention is always better than cure. It’s still better to prevent car battery damage than revive or replace a dead one. Make sure to use your car battery regularly. Fully charge unused batteries on a float charger before you use it to drive around. A float charger has a float voltage that maintains a full charge without overcharging the battery. Prevent excessive deep cycling. Make sure that your charging system is functioning properly. The Bottom Line
ThanQ Very much and happy to see such an article, which gives immense idea to rebuilt a laptop batteries to every electronic hobbyist
Description: you have to check specific gravity of electrolyte continuously in a car battery with the help of hydrometer. It consists if a cylindrical stem made up of glass, with a bulb weighed with Hg to make it afloat.
Your battery is designed to retain up to 80% of its original capacity at 400 complete charge cycles. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers a battery service. Prices and terms may vary.
The power meter reported a range in power between 2 and 18.3 watts during the charging period, consuming 0.046 kWh in total. From my utility company, that represents around $0.005 worth of electricity.
Step 3: Once you do that, you can check each cell group’s voltage to make sure they are all within range. If any of them are less than 2.5 volts or so, that group is probably bad. If you find a bad cell group, you are going to have to break the welds loose and remove those cells. It’s important to replace the bad cell or cell group with cells that are of similar capacity to the ones in the rest of the battery pack.
If you’ve got the courage and the know-how to do it yourself, you can buy a DIY kit, including the battery and all the tools you need. iFixit sells these kits and also provides you with comprehensive video repair guides.
