Hi I replaced my laptops battery cells. Now when I connect the battery to laptop it says fully charged but when I unplug the AC adaptor the laptop shuts down imidiately like I have no battery on it. I checked all connections and all it's fine. The plus and minus terminals of the battery have zero volts but the cells have 11.5 volts. I use the resistor to activate the solid-state switch but with no luck. I have to mention that I replaced the cells without keeping "alive" the circuit board. Why is this happening? Is there any way to bypass the board? thanks
Select the proper setting to fit the type of charge depending on the type of battery in your car and the speed of the charge needed. Usually there is a setting to charge 6V batteries, as well as fast and slow charging rates for 12V batteries. If you see a ‘crank assist’ setting, this is for simply jump starting the battery.

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.

If your battery has adequate capacity but still is losing its charge, further testing is required. This type of test includes determining the electrical draw of the starter and the output of the alternator.
9to5Mac reported today that the cost of an iPhone battery replacement will rise to $89 from March 1 on models ranging from the iPhone 11 upwards. The cost of a replacement battery for the iPhone SE and iPhone 8 will increase to $69. IPhone replacement batteries had previously been as low as $29 back in 2018 after Apple admitted that it was throttling the performance of older iPhones.
An in-warranty repair is free. If the device is out of warranty, a Repair Estimate Fee will apply. However, if you choose to accept the repair quote, the repair fee will be charged, and the Repair Estimate Fee will not apply in this case.
You heard me right. You do NOT have to buy a new $50 battery. You do not have to call the company and swear at them because this stupid "defective" battery is only 2 weeks old. (although by all means feel free to do so) You do not have to wait until they ship you a replacement battery to finish your project. You can get that battery up and working in about 5 minutes. A multimeter. (this is actually optional but helpful ... if you don't have one don't worry, you can still fix your battery)
Hi I have Samsung Series 9 ultrabook NP900 X3B A01UK. This ran out of charge and the light on the charger was not on. I replaced the charger with an originL Samsung unit the laptop powered up however the charger appeared to fail immediately and the laptop shut down. On unplugging the charger it was quite warm and again the power light is not on even though the fuse has not blown. It appears something in the laptop is causing the charger to fail. Do you have any advice, could this simply be caused by a failed battery or something more seriously wrong with the laptop? Kind Regards Len
DOUBLE CHECK THAT YOU ARE TOUCHING POSITIVE TO POSITIVE AND NEGATIVE TO NEGATIVE.
Either way you put your battery in the charger and all you get is a flashing red light, which according to the label on the charger means your battery is defective. It isn't just dead. It's "defective". I'm here to tell you you it isn't. You probably left it in the charger too long which weirdly drains the battery.
