Questions About Laptop Battery
Q. Do I need to charge my new Laptop or Notebook battery?
A. A new battery comes in a discharged condition and must be charged before use (refer to the devices manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity. When charging the battery for the first time the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Remove the battery from the device, reinsert it and repeat the charging procedure.
Q. Is it easy to install a Laptop Battery?
A. Yes, very easy. First, make sure all open files are saved. Next, either attach the AC adapter directly to the laptop or set the system to “”hibernate”” mode or shut off. Release the latch on the current battery, and simply install the replacement battery.
Q. How long will my Laptop Battery last?
A. The lifespan of a battery will vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.
Q. How long does a Laptop Battery last? When should I consider replacing mine?
A. All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new laptop battery when the run time does not meet your needs.
Q. How long does a Laptop battery last?
A. The life span of a laptop battery depends on a number of factors and is hard to predict. All rechargeable batteries wear out with time and use. As the battery begins to reach the end of its life, you will notice a decline in the runtime of the battery.
Q. How long am I able to use my laptop on a fully charged Laptop battery?
A. Many factors affect the amount of time that a laptop battery can deliver power before it must be recharged. Personal usage (your LCD brightness setting) has a large effect on battery run time and will vary greatly between different users and systems. Other factors include the system configuration (battery size, processor type, memory, etc.), and the types of applications being run (playing DVDs or games).
Actual battery life will vary based on configuration, operating conditions and other factors. Maximum battery capacity decreases with time and use.
Q. Should I completely discharge my battery before I charge it?
A. No, with current lithium ion batteries this practice does not improve the runtime of the battery.
Q. Should I totally discharge, then recharge my laptop battery occasionally to make it last longer?
A. No, discharging and charging does not increase the life of a lithium ion battery.
Q. Can a laptop battery be “”overcharged””?
A. No, the battery is designed to stop using the charger when it reaches full charge.
Q. How do I charge my Laptop Battery?
A. The battery charges in the laptop when the laptop is connected to an AC power source.
Q. Do I need to charge my Laptop battery fully when I get a new system or a new battery?
A. While not required, it is recommended to fully charge your battery.
Q. I generally do not unplug/undock my notebook. Does this hurt the battery?
A. No, the battery has built in controls which stop the charging process when the battery is full.
Q. What are the LED lights on my Laptop battery?
A. To check battery charge, press the button and the number of LED lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge.
Q. How do I get the most runtime for a charge?
A. It is important to choose settings which allow you to obtain the most runtime from your notebook. Examples to consider: timeout settings for the hard drive, Bluetooth, wireless, LCD brightness, etc.
Q. What can I do to make my Laptop battery last longer?
A. There are several things you can do to make your battery last longer:
– Choose the right battery. Under the same use conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
– Use the notebook’s power saving controls to reduce battery use in your normal day. For example, turn the Bluetooth off if it is not needed; reduce the screen brightness when conditions permit.
– Avoid exposure to extreme temperatures. If the system is exposed to extreme cold or hot temperatures, allow it to warm up/cool down before use and before charging.
– Contrary to last decades’ batteries, modern lithium ion batteries do not need to be fully discharged to maintain health.
– All batteries wear with use and time. When you find the runtime is no longer satisfactory, it may be time to purchase a new Laptop battery.
