Tips to make your Sony Laptop Battery last longer:

Sony laptop batteries are prone to lose their charge over time. It's important to know how to charge a Sony laptop battery, and what power-saving tips to use to extend the lifetime of your battery's charge.

Keep the sony vgn-cr21 battery contacts clean - Clean your laptop battery' s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your laptop battery more efficient.
If you do not use your sony laptop for extended periods of time (a week or more), remove the sony laptop battery pack from the laptop.
Do not expose the vgn-cr21 battery to high heat or freezing temperatures. Do not leave your sony laptop battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.
Take care of your sony vgn-cr21 battery - Do not leave a charged sony laptop battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a lithium ion sony vgn-cr21 battery completely discharge. (Discharing is only for older batteries with memory effects)
Fully charge new sony vgn-cr21 laptop battery before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.
Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the sony vaio battery in a constant state of charging up and that will reduce the life cycle of the battery.
