Sony VGP-BPL5A Laptop Battery Review
The Sony VGP-BPL5A laptop battery is a large capacity battery compatible with the Sony VAIO TX Series of notebook computers. These nine cell lithium ion batteries last an estimated 1.5 times longer than the standard VAIO batteries, without adding very significant weight to your machine at only 1.2 pounds. This product retails direct from Sony at $239.99, and there are many suppliers with compatible versions of this battery at a fraction of that price.
According to Sony’s website, standard batteries for the VAIO TX series last between four and ten hours, whereas this battery has a life of between 6 and 15 hours, depending on usage. According to user reviews, after a year of continuous use, this battery still retains approximately 6 hours of life when used for text editing.
Being a lithium ion battery, this component is useable directly after charging to 100%, without the need for any additional charging or multiple charge and discharge cycles. If using this battery as a standby, it should be charge to 40% and stored in a cool, dry place to retain full function. Also, check the battery every few weeks if not in use, charging it up to 40% as necessary.
Lithium ion batteries also function best with only partial discharge cycles, meaning that whenever possible, you should recharge the battery before it completely runs out. A lithium ion battery will typically last for between three hundred and five hundred charge/discharge cycles, or two to three years. This can be extended by storing the battery at a diminished charge (again, 40% is the magic number for lithium ion batteries), and at cooler temperatures (15 degrees Celsius is ideal). If using this battery as your main power source, this does not mean the battery will die in two to three years, rather it means that after two to three years, the charge capacity of this component will begin to deteriorate.
Overall, this battery is a great replacement for the standard VAIO TX Series battery, offering greater battery life at a very competitive price. Taking proper care of this component will grant it a long and stable life as well, lasting as long as the laptop itself will.
