The battery in your laptop might be an important component that makes your computer tick while it's not plugged in, but Windows doesn't exactly give you much information about it. The most you will usually get is an icon in the system tray, a charge percentage and a time remaining before it discharges completely. Other than that, the laptop battery status and detailed information is pretty much non existent.
You might also get the battery model and manufacturer if you're lucky. That might be enough for most people, but sometimes it's useful to have a bit more information than that. Windows can't give you any idea why your battery isn't holding a charge for very long, or if it's starting to show signs of wear. A lot of laptop batteries actually have a more information to offer than Windows decides to give you, so it's there but you can't get at it.
At Batteries Plus Bulbs, we want to make sure the battery in your cordless tool has the power to finish the project. We offer original brand batteries for popular cordless drills, impact drivers, saws, screw guns and more along with our own line of replacement cordless tool batteries that are built to meet or surpass OEM specifications. A 2-Step Process. This chart works for any voltage or voltage drop, American (AWG) or metric (mm2) sizing. It applies to typical DC circuits and to some simple AC circuits (single-phase AC with resistive loads, not motor loads, power factor = 1.0, line reactance negligible). STEP 1: Calculate the Following.
What you need is a 3rd party utility to get hold of this extra information for you, and like most things, there are a few around to help get hold of it. Here's a selection 5 of freeware tools to extract much more useful information from your laptop battery:
1. BatteryInfoViewBatteryInfoView is a handy little tool from Nirsoft to display the status and information values your laptop battery is capable of offering. There are around 20 different values that can be shown, but it depends entirely on what your battery can provide as to how many of these are available. Details such as the manufacturer and model information, power state, charge and wear capacities, charge / discharge rates and times and also temperature can be displayed and these values are updated every 10 seconds.
In addition to the main battery information window, pressing F8 will show the log window which is updated every 30 seconds and gives you an idea as to what the battery has been doing. From here you can see the charge or discharge rates over a period of time, and because the log records standby and resume, you can see how much the battery has discharged while in the low power state.
BatteryInfoView is a tiny portable executable of under 100K and is compatible with Windows 2000 and above.

2. BatteryBar
This utility displays less information in terms of numbers than BatteryInfoView, but still a lot more than what Windows provides. BatteryBar goes for a more user friendly approach and displays a very convenient graphical status of your laptop battery in the task bar which is much more readable than the Windows tray icon. This is accompanied by a popup status window that offers valuable information such as charge percent, capacity, charge / discharge rate, charge time left and a wear calculation.
BatteryBar also learns about the the discharge rate of your battery over time, and therefore the more you use the program the more accurate it gets at calculating the minutes left value. The battery graphic will change color depending on its status, blue means it's on A/C power and charging, green is high charge, yellow is medium and red a critical battery remaining.
The .NET Framework v2 is required to run the program and once installed you don't run an executable to start the program, but right click on the task bar -> Toolbars -> BatteryBar. This will show the battery status graphic on your task bar. Windows XP and above is supported.

3. BatteryCare
As well as being able to display several bits of information about your laptop battery and it's status, BatteryCare also tries it's best to help you extend battery life by giving you quick access to the systems power plans or even switching the plan automatically depending whether you're on battery power or plugged in. There are also some other power saving optimizations on offer when on battery power including disabling the sidebar, disabling the Aero theme and pausing high consumption services.
The program also has its own tray icon and notifications about low battery status, and interacting with the icon several different ways gives you different displays. For instance, hover over it to get a quick display with charge percentage, rate, HDD/CPU temps and power plan, left click allows quick changing of the power plans and a double left click displays the main information window where you can get basic or detailed battery information (pictured).
There is a portable version available if you look in 'more download options' on the website. BatteryCare works on Windows XP, Vista and 7 and the .NET Framework v2 is required.

4. Battery Status Monitor
Battery Status Monitor works by way of a little floating widget that you can drag to anywhere on your desktop that gives a bar and percentage of the charge status of the battery. Right click on the widget and you have access to other options which include changing the power scheme, standby, hibernate and also a useful option of quickly turning the laptop screen off. Very handy to save a bit of battery when you leave the computer for a minute or two, a hotkey for it can also be configured in the settings window.
Clicking on Battery in the menu will pop up a window with more precise status details about it. Clicking the Display menu option opens what doubles up as the settings window and a live graph of 8 functions including battery runtime, current charge percent, current system power consumption and some stats about the CPU. Some interesting settings are to disable Aero at a set battery percentage and also tweaking the AAM and APM functions of your hard drive if supported.
Battery Status Monitor is compatible with Windows 2000 and above.

5. Notebook BatteryInfo laptop battery detail in XP
Notebook BatteryInfo is similar to BatteryBar in that it can display a graphical representation of your laptop battery inside the taskbar. Sadly this program does not officially work on any version of Windows above XP which is a shame. It places a battery graphic on the task bar which shows the current state of charge, hovering over it will pop up a small window with a few more details such as the power scheme, consumption and amount of charge.
There are a number of options on how the task bar meter and pop up will look and also the types of statistic numbers to display such as percent or remaining time or power consumption. Detectx swift 1 044 – security and troubleshooting tool set. There is also a window for battery status values if you right click on the task bar meter and select 'Show battery values'. Something annoying the program kept doing though was popping up a nag reminder that Notebook BatteryInfo is for non commercial use only, once would have been enough.

ReplyThanks so much for article. A question: Are you aware of a simple program that, when called, will state if laptop is on battery or ac power? Best would be one that can write a small diskfile indicating if laptop is on battery or ac power. That way I can write a batch file checking for such a diskfile, giving me an alert when the AC isn't plugged in. Thanks in advance.
ReplyWonderful page, great options, info etc. After 3yrs of using my laptop(s), buying the same models as extras, so I could interchange batteries, reading up on how best to extend battery life, not keeping them in the pc, but doing a full discharge/recharge each month or so…. AND its only now, that I find this Great site, with all these fantastic options. Perfect for what I want & need.
Thanks so much raymond.cc, and all the developers who create and share this software. Cheers.

ReplyAnother good battery monitoring utility is Notebook BatteryInfo
ReplyGreat tool. Since I'm using Google Desktop, I'm using a gadget named 'Laptop Check' which gives all the information like processor usage, memory usage, network bandwidth usage and battery time.
ReplyIt works Properly.
Nice…
Thank You.
thanks a lot man
ReplyGreat Tool!
ReplyI'm the author of BatteryBar. Thanks for your great review.
If you have questions about it, you can contact me. There are links on my website.
BatteryBar fully supports XP, XP x64, Vista, Vista x64, and Windows 7.
Some people with certain netbooks have found that toolbars don't work on their laptops (including BatteryBar). There appears to be a configuration issue with the pre-installed Windows. It's also possible that it did not install properly.
Replyit is quite good…
thanks…
looks like a good tool. let me try it. thanks raymond

Electricity is measured in units of energy called watts, named after James Watt, the inventor of the steam engine. Watts is generally defined as the amount of power (or energy) an appliance uses (consumes) when operated at its maximum capacity for 1 hour . Amps on the other hand is defined as how much energy an appliance draws, or the rate of energy that flows through wire when an appliance is used for 1 hour. Finally, volts is what energizes the appliance or it is the force that pushes electricity through wire to the appliance. You can determine power characteristics of an appliance if watts rating is not provided, by the following equation: V (Volts) X A (Amps) = Watts (Ohm's Law)
A=W/V
V=W/A
To determine Amps consumed by a 25watt 12V light bulb, for example, use the equation A=W/V or (25/12=2.1Amps). Therefore, adding up amps figures for the various appliances you intend to plug into a Sunrnr will give you the total electrical load you will put on the equipment (or demand that it powers).
Please note that the proper selection of AC or DC appliances is an important factor, because it is better to have the power source and appliance working at the same voltage, so that, in a manner of speaking, nothing is lost in the conversion. For instance a 12V DC electrical circuit that supports a refrigerator will use power more efficiently if the refrigerator also operates at 12V DC. The efficiency level is lessened if a 12V AC powered refrigerator is connected to a 12V DC electrical circuit using an inverter.
Also, LED (light-emitting diodes) bulbs and Energystar rated appliances consume less energy and operate more efficiently. You can therefore run more of these types of appliances on a Sunrnr. Appliances that run at 240V AC- such as electric water heaters, cook-stoves, furnaces and air conditioners, are impractical loads to run on solar- whether generator or grid-tie. Alternatives such as LP or natural gas for water/space heating or cooking, evaporative cooling instead of compressor based AC units, and passive solar ideas are cost-saving options. The rule of thumb in the renewable energy industry is that for every dollar invested replacing inefficient appliances, three dollars is saved in the cost of a renewable energy system to run them.
LED bulbs replace 75W-100W incandescent bulbs with equal light output while consuing a ere 3W-13W. They last upward of 50,000 hours meaning if you leave a new LED bulb on for 8 hours/day it would not need to be changed for over 10 years. They are very efficient, use little electricity and therefore result in an immediate decrease in your electric bill.
Your utility bill, supplied monthly by your electric provider, is reported in Kilowatt Hours (KWh) of use (1 Kilowatt = 1000W).
To determine KWhs, multiply Kilowatts by number of hours of use. Therefore, a 60W light bulb used 5 hours a day consumes 300 watt hours or 0.3KWh of electricity.
