Did you know that detaching your main laptop batteries from your laptop would increase your laptop's battery life up to 75%? Our experience and testing have shown that even when you are plugged in with your laptop ac adapter and your battery is fully charged, the laptop will still use the laptop battery resources in small increments. This will put unnecessary charge cycles to your battery. Since typical li-ion laptop batteries have 375 charge cycles, having a fully charged battery inserted will put unnecessary charge cycles. The downside to removing your laptop battery maybe a loss of power when the ac adapter is accidentally unplugged or when there is a power outage.
