Is your once-trusty laptop now constantly tethered to the wall outlet? Do you find yourself scrambling for a power socket in the middle of important work? These are classic signs that your laptop battery is crying out for help.

At Longhehui, a leading manufacturer and supplier of high-quality replacement batteries, we understand the critical role a reliable battery plays in your daily life. Recognizing the symptoms of a failing battery can save you from unexpected shutdowns and data loss.

Here are the 5 most common signs that your laptop needs a new battery:

1. Drastically Reduced Battery Life

The most obvious red flag is a sharp decline in how long your laptop lasts on a single charge. If a full charge that used to last 6 hours now barely gets you through one, the battery's capacity has significantly degraded. All rechargeable batteries have a limited lifespan, typically rated for 300-500 full charge cycles. Over time, they simply hold less power.

2. The Laptop Dies Unexpectedly

Your battery indicator might show a healthy 30% or 40%, but then your laptop suddenly shuts down without warning. This is a clear sign that the battery can no longer provide a stable voltage under load. It's unreliable and can interrupt your workflow at the worst possible moment.

3. The Battery Won't Charge to 100%

Pay attention to your charging habits. If you notice your battery gets "stuck" at a certain percentage—say, 85%—and won't charge fully even after being plugged in for hours, its internal cells are likely failing. Your laptop's power management system is detecting an issue and stopping the charge to prevent damage.

4. Physical Bulging or Swelling

This is a serious sign that requires immediate action. If your laptop case seems warped, the keyboard is protruding, or the trackpad isn't clicking properly, your battery may be swelling. Lithium-ion batteries can swell due to internal gas buildup from aging or damage. Stop using the device immediately and remove the battery if possible, as this can be a fire hazard.

5. Overheating During Use or Charging

While it's normal for a laptop to get warm during intensive tasks, excessive heat coming from the battery compartment is a major concern. A failing battery often works harder to maintain a charge, generating abnormal amounts of heat that can damage other internal components.
