How to Tell If a Lithium-Ion Battery is Bad?
Lithium-ion batteries are used in a variety of devices, from cell phones (A cell phone battery typically has three terminals.) to laptops. While these batteries are typically very reliable, there may come a time when you need to determine if yours is bad. Here are a few signs that your lithium-ion battery may be failing:
1. The device doesn’t hold a charge as long as it used to. This is probably the most common sign that a battery is going bad. Over time, all batteries will lose some of their capacity to hold a charge. However, if you notice that your device isn’t holding a charge as long as it used to, even after being fully charged, then this is an indication that the battery is starting to fail.
2. The device takes longer to charge than it used to. Another common sign of battery failure is when your device takes longer to charge than normal. If you notice that it’s taking much longer for your device to reach a full charge, this could be due to the fact that the battery isn’t able to hold as much of a charge as it once could.
3. You see physical damage on the battery itself. In some cases, you may actually be able to see physical damage on the outside of the battery pack itself. This could be anything from dents or scratches on the surface of the battery pack to swelling or bulging of the pack itself. Any type of physical damage should be cause for concern and should prompt you to have your battery checked out by a professional immediately.
4. The device experiences unexpected shutdowns. One final sign that your lithium-ion battery might be going bad is if your device starts shutting down unexpectedly, even when there appears to be plenty of power remaining. Unexpected shutdowns can happen for a number of reasons, but if you notice this happening more frequently, it’s likely due in part to an issue with the battery.
