How Long Would Original Laptop Battery Last Before Needing Replacement?

We know that some of you out there might really want to know how long a new and original laptop battery can at least last before getting very weak and needing outright replacement.

But before we go ahead to give you real insight on what to expect in terms of original laptop battery duration/lifespan, there some factors to consider, like the laptop usage frequency, good/bad laptop charging practice, laptop type etc.

We are going to be generic here in dealing with this topic and in the general we would be considering normal laptop under heavy usage that is mostly used either outdoors or with the battery as source of the laptop power in most occasions.

Now, this is it; for an original factory fitted laptop battery or original replacement battery you bought, under heavy usage and proper laptop usage and charging conditions, the battery can last for up 4 to 5 years before being completely weak and needing urgent replacement.

For example, initially, if your original laptop battery powers your unplugged laptop for 6 hours when watching media files like videos or 5 hours when connected to the WiFi, after 4 to 5 years of constant usage, you can barely get an hour of battery juice with your laptop and at that point, you should consider replacing the battery with another original one.
