Other Laptop Accessories: Laptop Battery Tips: Our replacement HP QK640AA laptop battery is usually lower in price and meets or exceeds the specifications of OEM HP QK640AA laptop battery. New HP QK640AA laptop battery comes not in a fully charged condition (normally 30% state of charge). You can use the HP QK640AA battery in your laptop computer until the computer sends out a low battery power warning or the laptop shuts off itself; then, fully recharge the battery. It needs three to four discharge/charge cycles to achieve maximum capacity of the HP QK640AA battery. Detaching your main laptop battery from your laptop will increase your laptop's battery life up to 50%. Do not store the HP QK640AA laptop battery completely discharged. A 50% charge is optimum for storage. Self-discharge on a depleted battery may trigger the built-in protection circuit which will hold back a recharge. Prevent the Memory Effect - Li-Ion batteries do not suffer from the memory effect, but Ni-Cd, NI-Mh batteries have memory effect.
