Typical install takes 15–25 minutes. A basic tool kit is included. Power off, unplug the charger, and handle the battery by the edges only.
We accept major credit cards and PayPal via secure checkout.
Not always. Fast draining can be caused by background apps, settings, or an old battery. If your battery lasts less than 30–60 minutes unplugged, it’s usually time to replace it.
Yes, in most cases. This is a common sign of a worn-out battery. A new compatible battery should restore normal portable use.
Many laptops limit charging to 80–95% to extend battery life. If it’s stuck much lower, the battery may be failing and should be replaced.
Check seating and contacts first. If the issue continues, the battery is likely faulty and replacing it will usually solve the problem.
Yes, but long-term constant charging can reduce battery lifespan. Unplug and run on battery once or twice a week to keep it healthy.
Most laptop batteries last about 2–4 years or 300–500 charge cycles, depending on usage and care.
