Are you concerned that your battery is failing and will need to be replaced? Are you looking for a second-hand laptop and want to check the laptop’s battery health to make sure the battery is in good condition before purchasing?

- Battery health also known as battery lifespan, refers to the condition of your current battery. It refers to how long your battery can last before needing to be replaced. It determines the rate at which the battery’s life decreases over time.
