One of the best things about MacBook laptops is their long battery life. Typically, they last in the ranges of 10 hours on a single charge, but that is if the battery is still under new conditions; less than 1,000 charge cycles.

Nonetheless, if you are on a long flight, or out doing field work with no wall power outlet access. You might want to grab one of these portable batteries for when your computer when it runs out of juice. They work in much the same way power banks charge your low-battery smartphone.

It is important that the portable battery you choose be compact and light, so it can easily fit inside your laptop bag without weighing you down. Though not all come with the MagSafe connector like Apple charges.

Some people tend to leave their laptops plugged in throughout if they know they will need to leave and will not have access to the wall power outlet for some time. This behavior shortens your battery life; it is recommended you remove the charger once your battery is fully complete.

There is a long-standing debate as to whether you should wait for your laptop to be critically low on battery before recharging; and when recharge you must wait until it is 100% full. Or should you recharge at 20% mark and can comfortably remove it from charge at 80% mark. There are those who believe the first argument actually shortens the charge cycle of Li-Ion batteries, and recommend the second point of view. You will need to research further to establish what’s correct for your laptop.
