How to charge a dead laptop without a charger

A new life for a used battery

Lithium-ion batteries power most consumer electronics, and they have even reached hybrid and electric vehicles. Unlike ordinary alkaline batteries, lithium-ion batteries are expensive to replace.

A Lithium-Ion (Li-Ion) battery is a rechargeable battery, but even batteries have a limited number of cycles before the performance begins to deteriorate. Over time, it takes longer to charge them and they lose their charge much faster.

So, if the lithium-ion battery in your laptop has seen better days, there are a few things you can try to bring it back to life before spending money on a new one.

Fully charged

If  your laptop battery is no longer holding its charge - it drains very quickly, you may be able to save it by doing a full charge. In order to complete this task, you must discharge the battery completely. To do this after reaching zero percent, try to continue turning on the laptop until none of the LEDs even blink, and then try to turn on the computer a dozen more times and hold down the power button. Now connect the charger to the laptop, do not turn it on and leave it to charge for at least 48 hours

If the battery you are trying to repair is used with a computer you use on a daily basis, you will have to complete the procedure over the weekend or find a replacement computer for two days.


The same freezer that you store your frozen pizzas and dinners in can often bring seemingly dead laptop batteries back into service.

1. Place the discharged laptop battery in an airtight plastic bag.

2. Place the bag with the battery in the freezer for about 12 hours.

3. Take the bag out of the freezer and allow the battery to warm to room temperature, and occasionally clean it with a towel if it becomes wet.

4. Place the battery in the laptop.

After regenerating the battery in the freezer, it is recommended to carry out the full charge procedure in the previous paragraph.
