Tips about how to make your VGN-TT21M/N laptop battery last longer?

  1. Charge your Sony VGN-TT21M/N battery to its full capacity the first time and every time- New batteries almost always arrive completely discharged. Give your laptop battery a complete charge upon receipt, and allow it to fully charge each time you plug it in.
  2. To prolong Sony VGN-TT21M/N battery life is to take care of your battery
    Once a month, you will want to clean it and this is a very easy and simple task. All you need is a small cloth and a bit of rubbing alcohol. A wipe across your VGN-TT21M/N battery where it makes connection one time per month will give you better transference of power, thus extending the life.
  3. How to make your Sony VGN-TT21M/N battery last longer each time?
    A: If you do not need a program any longer, just take those few seconds to close it down and this can greatly help. Instead of your VGN-TT21M/N battery using precious power for a program you are not even using, you can extend its life by just asking it to give you power for what you actually need.
  4. Never short a battery to fully drain it. By short, I mean that you connect the two terminals (positive and negative) directly so that the Sony VGN-TT21M/N battery simply drains. This is a very bad, stupid thing to do. It can cause a fire. Don't do it.

Let me start out by saying that I was quite skeptical of buying a battery online for half the price that Sony offers them at, but being the extremely broke college student that I am, I really didn't have much of a choice. Let me tell you that so far, this product is great. (its only been a few days, but all seems well) Fits perfectly into my laptop, and holds a charge for over 3 hrs while surfing the internet and through constant use. I would suggest your site to anyone and am extremely satisfied.


This fits perfectly. I've had this for 3 months and no problems at all. Received the product very quickly. Very inexpensive for a battery that still works. It even lasts longer then my previous battery. A great buy!
