Laptop Battery Life

There has been a group of chat recently about laptop battery life. Battery is a consumable electronic product with limited life, but correct use, proper charging and discharging as well as good storage would significantly prolong the laptop battery life. Your laptop battery, you observe, starts losing capacity as soon as you drive it off the lot, and after a year or two you might need to get a new battery just to get an hour or two away from an outlet.


So, what steps can you take to make the battery extended as possible? I’m not talking about optimizing the runtime on a single charge. I am talking about getting as much as possible from a battery before you have to replace it just to get a reasonable runtime out of each charge. Here are a few things you can get the most out of your laptop battery:


1. Keep your laptop battery cool. Batteries humiliate more quickly when they’re hot. That means you should keep vents clear — don’t put your laptop on a feathery pillow or a cushioned surface that will cover vents and catch heat.


2. Don’t pack your laptop away in a bag or other enclosed space when the battery is still warm, trapping the heat. A battery that’s frequently hot to the touch will lose life a lot faster than a battery that isn’t constantly being stressed. Worst of all: If your laptop crashes or refuses to shut off properly, the battery can get really hot when packed away in your bag. Check it to make sure it hasn’t gotten dangerously hot while stowed away over the weekend.


3. Don’t charge your laptop continually. If you only occasionally take your laptop away from a power outlet, but leave it plugged in to charge 24/7, you’re leaving your laptop in a state of perpetual charge at the 100% point — and that is bad for the battery’s long-time health.


Right Ways to Charge a Laptop Battery for the first time:


When charging the battery for the first time your computer with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
It is necessary to discharge the battery to 0% before recharging it the first time when you use the battery. If you discharge a new battery till the computer goes to hibernation before recharging, the internal microprocessor of the battery can calculate the capacity more accurately.
Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity. The charging process should last at least around 14 hours.
Do a full cycle (charge and discharge) under protection circuit control during a certain period of time to re-modify battery capacity calculation, but it won’t enhance the actual capacity of the battery.


4. If you tend to use your laptop mainly at your desk, exercise your laptop battery by running it down and recharging it once or (even better) twice a month.


5. Alternately, you might want to actually remove the laptop battery if you’re using the laptop at your desk for long time. If you do remove it, don’t store it in a fully charged or depleted state. It’s best to store it in the middle — between 40 and 50 percent of full charge A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a certain storage period. Surely it would be great if you can use the battery once in a month to ensure good storage status.


Calibrating Your Computer's Battery For Best Performance


The battery has an internal microprocessor that provides an approximation of the amount of force in the battery as it charges and discharges. The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate. You should perform this procedure when you first use your computer and then every few months subsequently.


1. Plug the power adapter in and fully charge your computer's battery until the battery indicator lights turn off and the adapter plug light goes from amber to green, which indicates that the battery is fully charged.


2. Disconnect the power adapter and use your laptop. When your battery gets low, you will see the low battery warning dialog on the screen. Continue to use your computer until it goes to sleep. At that point the battery has been adequately drained for calibration.


3. Connect the power adapter and leave it connected until the battery is fully charged again.
You have to fully charge and then discharge your battery only once to calibrate it. After that, you can connect and disconnect the power adapter when the battery is at any charge level
