How to care for your Apple 17-inch MacBook Pro battery. You can extend the life of your Apple 17-inch MacBook Pro A1189 A1212 A1229 A1261 661-4231 661-4618 laptop battery significantly through the proper care and handling of your battery. Any new Apple 17-inch MacBook Pro laptop battery should first be fully charged by leaving it plugged in overnight. Once a computer battery is fully charged it will no longer accept any more power. It is a common practice to leave laptops plugged in after they have been turned off so that the battery has a full charge the next time you use your laptop. It is probably fully charged within 5 hours. A brand newApple 17-inch MacBook Pro notebook battery is in a weakened condition since it has not been conditioned yet. Condition and break in your new battery by performing 5 partial discharge and recharge cycles the first week you receive your new battery. Run on battery power without the AC adapter cord at least once a week to keep the battery cells active and at their peak potential. When your laptop is plugged into the power adapter the battery goes to "standby mode" while your laptop runs directly on electricity from the wall outlet. Even though yourApple 17-inch MacBook Pro battery indicates it is fully charged, your battery will return to a weakened state again in a few months if it does not get some exercise through partial discharge and recharge cycles while running on battery power alone. If yourApple 17-inch MacBook Pro battery has not been actively used 2 months or more, condition your battery again with 5 partial discharge & recharge cycles to increase the batteries capacity and run time. Don't run yourApple 17-inch MacBook Pro battery all the way to empty. Your battery will have a longer service life if it receives shallow discharge and recharge cycles. Research has shown that the useful life of the battery will be much longer if you begin to recharge the battery any time before reaching 20% of the remaining power capacity. Recharging the battery even after 10 minutes will not reduce the battery's life span as lithium batteries do not have the memory effect which was found in older NiCad battery technology. NiCad batteries have never been used in laptops, even the earliest models. Never run yourApple 17-inch MacBook Pro battery below the 2% critically low warning point. If your battery is run below this point it may not have enough energy to even recharge. This may effectively "kill" your battery. How can I extend my Apple 17-inch MacBook Pro A1189 A1212 A1229 A1261 661-4231 661-4618 battery run time?
