Laptop batteries, like any Lithium-ion (Li-Ion) battery degrades gradually over time, no matter where you buy it from or whatever any sales person says otherwise. It's just the way the technology works. I've listed a few tips that could really keep your battery alive.

1. Keep the battery charged. I like to say, charge early and often - Although all Li-Ion cells will lose their charge from age eventually, recharging Li-Ion Batteries often and early makes sure the charge is maintained throughout all the cells in the battery.

2. Don't frequently Discharge and Recharge the Battery - This is called a “Deep Cycle” and should only be conducted to re-calibrate the electronic device's battery meter. Once every 30 - 40 charges is very appropriate. Without re-calibration, the battery meter could show empty when the battery still has a large amount of charge. This can be particularly annoying in laptops if software is relying on the power meter to run effectively.

3. When using your laptop for a long time take out the battery – Batteries degradation is rapidly intensified with heat. If your using the laptop for a long amount of time during the day, it's best to remove the battery completely and store it in a cold place (such as your fridge or freezer*)

4. *Never freeze your battery - The Freezing point of most Li-Ion Batteries is around the -40 degrees C mark, way below most household freezers.

5. Absolutely don't deplete your battery below it's minimum (2.4V – 3.0V per cell)

Your battery should last a while if you do all of these. I've found generally keep the battery out of the laptop and away from hot areas, and it'll keep it like new. If your still after more specific knowledge, try the Battery University.
