What will you do when you drop your laptop battery or damaged? One thing for sure is confused.
Although we can still use the laptop without the battery or buy a new laptop battery.
This experience I have gained a few days ago, when my laptop battery actually drop, then I ask someone who is an expert in the field of computers (when there are computer fairs) on how to take care of laptop batteries.

1. Do not turn off the battery condition laptop less than 40%.
2. Do not charge until the fullness of time the laptop died.
3. Do not remove the battery when turned on laptop (AC mode).
4. Remove the battery if the laptop is not used in a long time (+ - 24 hours)

There are ways to keep accurate batteries last a long time:
1. Charge up to full while the laptop is used for activities laptop
2. Enable hibernate system
3. Use a laptop while on the move and wait until the battery runs out and use the system and leave the laptop hibernate for + - 8 hours, the battery still stuck.

The above ways are notified by any means an expert in his field when there is an exhibition at my college.
