However, as the laptop ages, it is possible to lose some power and there may be a fair chance that you need to replace the battery.

If your laptop is showing troubling signs during charging or it is overheating or shutting down abruptly after full charge, these are all signs that hint towards the fact that your laptop battery needs replacement.

Sometimes, there can be some other battery failure signs that you may need to also look out for.

Never Ending Power Issues

Though power issues can also signal something else, more often than not, it is a sign of a faulty battery.

If your laptop shuts down unexpectedly in the middle of a work session despite being fully charged, you must take it to a specialist for a thorough check-up. It is a big possibility that your battery needs replacing.

Besides, a laptop that shuts down unexpectedly is anyway a cause of concern that must be checked regardless.

Overheating Too Often Too Much

In such a situation, you should unplug your laptop from the source of power, let it cool down and not use it, if possible. You should, of course, take it to an expert to get the battery fixed.

Your Laptop Is Past Its Hay Days

Shelf life is an actual thing, especially when it comes to a machine. No matter how well you look after your laptop, it is bound to show wear and tear that comes with age.

If your laptop is not charging at the pace it usually does, it is highly likely that your battery is past its prime and needs replacement. Laptop batteries are designed in a manner that they charge quickly and get to work and if that’s not the case, all is not well.

Sometimes, it may not charge at all. If this happens, you should take this failure to charge as an indication that your laptop battery needs replacement.
