Usually, a dead battery will not harm your laptop if you leave it in. If the battery is completely ineffective, then no electricity will flow through it. And without electricity, there is not much of a chance for it to overheat or bust and cause you damage. So, you can leave it in and not worry about it too much.
Of course, it always needed a stable power connection and unable to carry along with. So, It was limited in that sense.
In rare cases, the battery may start to leak. At that point, it is a considerable threat to your pc and your own health. Battery acid is very corrosive and will burn your skin on contact. It may also seep into the interior of the laptop itself and cause damage.
How to replace a battery
How easy it will be to replace a battery will depend on the device you’re working with. It can be a simple process involving a single screw, or an incredibly complicated enterprise that requires you to disassemble your entire computer and melt an incredibly sticky adhesive while you try not to break anything.
If the battery starts to fail within the warranty period, the easiest thing to do is to contact the manufacturer, as they might cover the part and the replacement. If your warranty is expired, you can take your device to a repair store—or replace the battery yourself.
Be Nice to Your Laptop Battery
Before you buy a new computer, think about whether it could be the battery instead. Laptop batteries are not manufactured for eternal recharging. You might think you’re doing the right thing by keeping it plugged into a wall charger all of the time, but you’re actually doing your battery a favor by unplugging it every once in a while.
One other suggestion: don’t let the computer get below 20% charge before plugging it back in. This can help preserve battery life.
