The plug on A.C. power pack for Samsung NP-Q430 has been cut off. Can I use it by placing the (+,-) wires between the laptop pins and battery ports?
The place of your restored battery pack is usually a SR-50(A), SR-51(A), SR-52, SR-56, TI-58(C) or a TI-59.

There are certain signs that indicate that your battery is nearing the end of its life. The most obvious of these is the range. If you have stored your e-bike for a longer period of time during the winter and, come your first tour in spring, you no longer get as far as you did before, this is a clear sign that the battery capacity has decreased. There may be various reasons for this, such as low tire pressure or a problem with the e-bike motor. However, it may also be that battery is slowly but surely failing. To be certain, you need to establish the battery's residual capacity. You can do this at your nearest workshop using the FIT e-bike analysis tool.

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 ?
whats wrong on your laptop or garger or battery.write little more about problem?

Remove the display from the aluminium frame by gently pushing it upwards with a hard plastic plectrum.When the display is completely detached, you can slowly fold it up to the side of the standby button.Lean it against a stable object so that it remains in a vertical position. Disconnecting the battery
Certain mobility scooters don’t have your usual VRLA batteries to power them. Some have specialist Nickel or Lithium battery packs that can be hard to find a replacement. Luckily, a selection of the battery packs that we refurbish are specialist mobility scooter battery packs.
This can be due to 2 reasons. One, the battery of your iPhone is not operating at its peak performance capability. You can check the health in Settings. Second, your operating system and apps may not be updated that causes battery drain while usage.
Thanks for the information. I tried it on a 2ah, using a 12V car battery trickle charger. I got the battery pack up to 11.5 volts; but it still won't charge. Is there a way to see if I have a dead cell (other that cutting the cell connectors) and replace a dead cell? Or, is there something else wrong with my battery? Thanks.
I know a lot of us are working from home right now. And many of us also have kids at
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.
As lithium-ion cells age, the battery slowly loses its ability to maintain as high of a voltage for as long as it used to.
If the battery is fully discharged ( like if something stayed on overnight) your battery charger may not work. If so, and you can’t connect directly to another car’s battery, you can remove the dead battery, take it to the other car, and jumper it there. After about 5 minutes, remove the jumper cables and the charger should work.
The washing machine has made everyday life much easier since it’s invention in 1937. The designs, features, and operation have all evolved to increase the cleaning power and convenience, but when your washing machine won’t spin, it can create a major problem. Debbie D. 10 min read 02/13/23
