How to Charge a Laptop Battery Without a Laptop

A universal complaint from otherwise happy laptop owners is their machines’ dismal battery life. A two-to-three hour work limit imposed by a standard laptop battery offsets the whole idea of a portable computer. One solution is to carry a spare battery, which hopefully you remembered to charge in your laptop at some earlier time. And now, of course, you have to remember to charge the weak battery . . . in your laptop . . . whenever that becomes convenient. Ugh. It’s no wonder laptop battery management can cause migraines. Wouldn’t it be great if there was a way to charge your spare (or spares for maximum efficiency) without having to tie up your laptop for the job? To have a fully charged battery always at the ready? You might have guessed by now that there is. Here’s what power users do to keep their batteries charged without sacrificing their laptops to get the job done.

How to Charge a Laptop Battery Without a Laptop

Step

Buy an external laptop battery charger. These devices have a plug that connects to your laptop’s battery, and another that connects to an AC power source (i.e., an electrical outlet). They are usually brand and model specific (universal chargers are very hard to find), so make sure you know your laptop’s exact model number. A couple of places to start looking are listed in the Resources section.

Step

Remove the weakened battery from your laptop. First make sure you turn the laptop off or place it in hibernation.

Step

Attach the battery to the external charger. Plug the charger into an available outlet. Wait until the battery is fully charged. (The time will vary from unit to unit.)

Step

Return the newly charged battery to your laptop and power up your computer.

Step

Charge any spare batteries for future use.
