How to salve A battery will not lose its charge sitting in storage from happybattery.com.au

June 2, 2011 - PRLog -- Depending on the type of battery and temperature, batteries have a natural self-discharge or internal electro chemical "leakage" at a 1% to 25% rate per month. Over time the battery will become sulfated and fully discharged. Higher temperatures accelerate this process. A battery stored at 95° F (35° C) will self-discharge twice as fast than one stored at 75° F (23.9° C).
A hundred years ago battery cases were made of porous materials such as tar-lined wood boxes, so storing batteries on a concrete floor would accelerate their discharge. http://www.happybattery.com.au/laptop-battery/Dell/studio-1440.htm   Dell studio 1440 battery
  Modern battery cases are made of polypropylene or hard rubber. These cases seal better, so external leakage-causing discharge is no longer a problem, provided the top of the battery is clean.
There are a number of factors affecting an alternator's ability to charge a battery, such as how much current from the alternator is diverted to the battery to charge it, how long the current is available, and the temperature. Generally, idling the engine or short stop-and-go trips during bad weather or at night might not fully recharge the battery.
There two types of battery explosions are external and internal. Recharging a wet lead-acid battery produces hydrogen and oxygen gasses. While spark retarding vent caps help prevent external battery explosions, sparks occur when jumping, connecting or disconnecting charger, or battery cables and ignite the gas.

Internal explosions usually occur while starting the engine and normally blow the filler caps or cover off and splatter electrolyte all over the engine compartment. The most probable cause is from a combination of low electrolyte levels in the battery and a low resistance bridge formed between or across the top of the plates called "treeing" between a positive and negative plate. When heavy current flows in the battery such as starting an engine, a spark occurs and ignites the residual gas in one or more of the cells. A second possible cause is a defect in the weld of one of the plate connecting straps.

An interesting feature that I haven't seen on other notebook models is the removable dust filter that will make it easier to keep clean. My only concern is how well the filter will stay in place with repeated use. Will it loosen up over time? That we'll have to wait and see.
The internal display is 4” and while I initially wasn’t sure which way to take advantage of it or how to get the best viewing angle. It was useful when using a messaging program as I could keep that program in the small display and still work on things in the main display

One of the worst things that can happen while working on a laptop is to have your Laptop Battery die mid-project. To avoid this, it's good to know how much life your battery has left in it.
