How to charge my ASUS epc1000heb-blk001x battery

The battery charging circuit inside the netbook is much different that using a dc power supply. You'll fry the battery using one.

My dell battery will not charge anymore. it says

Charging circuit on motherboard or you can try a different A/C adapter. Start with the adapter first, they're pretty inexpensive $20-$35. If that doesn't fix it then a motherboard replacement is your solution unfortunately. Check with Dell on your warranty options.

You are not doing anything wrong, chances are that you just did not fully discharge this battery before charging. You will notice that all batteries will vary from charge to charge, but this is normal. Have fun with the cars. Hope this helps.

My laptop computer ibm t42 does not charge the battery

Hello....those T40 series laptops which I use to support at a previous job. They would often develop these same issues. We would often keep them in stock because after a while the batteries just don't hold a charge. Its not that the laptop is not charging them. The battery simply does not hold the charge.

Because of BIOS. Basic Input/Output System.
Battery has 'lost track', of what the battery state of charge is.

Try Recalibrate BIOS

New 6600 mAh battery won't charge

Is the AC adapter the original that came with the laptop or is it a replacement?
Check the label on the laptop (on the bottom of the laptop) for the voltage and current requirements.
Check voltage output of the adapter with a multimeter, this voltage should be slightly higher that the voltage than what is shown on the adapter's label because there is no load on the adapter.
It could be that the current (amps) that the adapter is delivering less power than the laptop's requirements, whilst it can power the laptop it may not be sufficient to charge the battery fully.
Try charging the battery overnight by shutting down the laptop but leaving it connected to the mains. Then boot up the laptop in the morning and check the battery's charge state. If the battery is at or near full capacity, then the problem is a (part) faulty adapter.

Initial charging time

hi there
the first charge should be around 12 hours, this then teaches the battery its max load.
ignore the charger if tells you its charged after a couple of hours.
after the first charge use as normal.

hope this helps
