Top 10 Laptop Battery Basics

Take care of your laptop battery and ensure that it will be ready to work properly when you need it most. Some general tips for laptop care include: avoid extreme temperatures, don’t leave a laptop outside in cold weather or leave it in a hot car. Cold batteries can’t create very much power and hot batteries will discharge very quickly. Use electrical power when available to keep battery charged. Don’t let your laptop go for long periods of time without using the battery.

1) Smaller Is Better
Consider an ultraportable or thin-and-light rather than a desktop replacement laptop. Smaller displays use less power. Going with a hard drive that runs at 4200rpm uses less power than a hard drive running at 5400rpm.

2) Power Control
Use as little power as possible by adjusting laptop settings. Use the Power Options to set to the laptop to go inactive after a set amount of time. Set adjustments so that the display goes off first, then hard the hard drive stay active a bit longer and store the system content’s to the RAM.

3) Turn Down the Lights
Adjust the display brightness to a lower setting, make sure you can view the screen without squinting. You can also adjust the brightness of the display to suit the conditions you are working in.

4) Watch Your Battery Use
Keep an eye on your battery consumption and know how much power you have remaining. Use the battery power icon on the system tray or you can purchase batteries which have LED gauges on the outside of the battery itself.

5) Charging It Up
Whenever you have access to a power source, charge the battery. Before you leave on any trips, fully charge the batteries, especially if you don’t know where or when you might have access to any electrical outlets.

6) Get Another Battery
Some laptops are capable of running with two batteries. If you cannot run two batteries, check with the manufacturer to see if there are high capacity batteries available. External batteries can also be used to extend operating time.

7) Drain the Battery
The first time you use your laptop with battery power, allow the laptop battery to completely discharge. Do this at least twice and don’t try to charge the battery when it is half discharged.

8) Clean Batteries
Keep the battery and its connections clean and free of debris. Clean your battery terminals on a regular basis using a cotton swab with rubbing alcohol on the tip.

9) CMOS Battery Check-Up
The backup battery is a CMOS battery which is a secondary battery to power the clock and can drain a main battery if it is dead. Check with your User Manual or manufacturer’s web site for the location of the CMOS battery and where to get a replacement.

10) Turning It Off
Don’t run programs or devices that you aren’t using. Remove PC cards and turn off Wi-Fi software. Using your laptop to watch movies or play games will drain the battery quickly as well.

If I overcharge my laptop battery, will the life span decrease?

First it’s important to understand what overcharging is:
Over-charging occurs when the charger keeps the battery at a temperature that is warm to touch (body temperature) while in ready condition.

Li-Ion laptop batteries have built-in controller chips which prevent it from overcharging, as they can explode if overcharged. Overcharging does not affect the life span other than potentially destroying the battery.

A lithium-based battery should never be allowed to get warm in a charger. If you have this happen, the battery is no good or the charger is not working properly. Don’t continue to use the battery or charger if this happens.

A Lithium-ion battery may be damaged by extensive overcharging (continuously on a charger for more than 24 hours). Damage to the battery from overcharging would only occur in the very unlikely event of a malfunction of the charging system.

How to calibrate the battery

Most laptop batteries are smart; meaning that they know how much energy is left. Such a feature has definite benefits but the readings are often inaccurate. A laptop may indicate 30 minutes of remaining runtime when suddenly the screen goes dark. Here is the reason why:

With use and time, a tracking error occurs between the chemical battery and the digital sensing circuit. The most ideal use of the smart battery, as far as fuel-gauge accuracy is concerned, is a full charge followed by a full discharge at a constant current. In such a case, the tracking error would be less than 1% per cycle. In real life, however, a battery may be discharged for only a few minutes and the load may vary widely. Long storage also contributes to errors because the circuit cannot accurately compensate for self discharge.Eventually, the true capacity of the battery no longer synchronizes with the fuel gauge and a deliberate full charge and discharge is needed to re-learn or calibrate the battery.

What happens if no battery calibration is done? Can such a battery be used in confidence? Most smart battery chargers obey the dictates of the chemical cells rather than the electronic circuit. In this case, the battery will fully charge regardless of the fuel gauge setting and function normally, but the digital readout will become increasingly more inaccurate. If not corrected,the fuel gauge simply becomes a nuisance.

At what point of a discharge does the reset occur? Lithium-ion is considered fully discharged between 2.5 and 3.0 volts per cell. The electronic circuit in the battery is designed to reset between these voltage levels. A problem occurs if the laptop cuts off before this low voltage can be reached. In such a case, an external charger with discharge function may be used. Cadex Electronics manufactures smart chargers and battery analyzers, both of which can be used to test and calibrate the smart battery.

All of the battery has a natural course of discharging, after preserving for a long time; it has already finished discharging naturally. This does not influence the capacity of the battery. While charging for the first time, you should charge the battery to 12 hours continuously, circulation fill, discharge three (consult battery maintain first) by waking the new battery up completely totally, if the battery deposit several months, propose, go on complete filling, discharging 3 times to it too. If one battery still can not be charged after the 12 hour or three circulations this battery can not use needing to change.

Knowing the information above, while use the machine we should pay more attention to these items 1 try to fully charge and discharge the battery while using the machine. 2 Fully charge and discharge the battery once every two months. 3 If there is problem about the battery, our advice is pls try it by yourself first or contact to the service center to examine the battery.
