Are old laptop batteries a fire hazard when low on capacity?
Asked by

My family is using some old laptops that show a warning about low battery storage capacity when we try to use them without being plugged in. My mother is really worried about the possibility of these batteries exploding or catching fire. We're okay with using the laptops as long as they're safe to use while plugged in, but is there a real risk of danger? Should we take immediate actions regarding these batteries?

Old batteries can become unstable while charging, so there is a slight risk if they're in a bad shape. I had a battery blow up in an office once while it was charging overnight, so it's something to keep an eye on. Just check if yours is swelling or bulging. If yes, it might be best to remove it when plugged in.

I’ve been using my laptop without the battery for years now. It’s been fine just using it plugged in. Just note that not all laptops may work the same way, so you might want to try it out.

Most laptops can actually run without a battery as long as they're plugged in. You might want to try removing the battery and see how it goes without it. Just make sure you're okay with performance drop in case your laptop needs the battery for that.

If the battery isn’t bloated, you should be all good. Just keep an eye on it; that’s really the biggest warning sign. Otherwise, using it plugged in is usually safe.

From my experience, some laptops actually throttle performance without a battery. Some business models have settings in the BIOS for this. If you’re just using it plugged in, consider checking for that or even getting a battery replacement if it’s super cheap. It could be a good option.

When the battery starts swelling, that's definitely a big red flag. I usually take out the battery and just use the laptop plugged in, and reinsert it only for aesthetic purposes once I'm done. Monitor your battery regularly for any changes.
