using laptop without battery

Posted 19 November 2015 - 05:14 AM

i always use my laptop without battery because i dont need the battery also what im afraid of is that if i used it too much it will die. i did a google search and found this result:

Quote

For most lithium-ion laptop batteries, the time it takes for them to lose 80 percent capacity is one to two years.
, my laptop is more than two years old now and i read that keeping it plugged in will affect it

Quote

keeping it plugged in to the laptop A / C adapter will reduce the number of battery cycles. However, not using it at all can shorten the battery’s life as well. While plugged into a power source, the batteries remain fully charged and are effectively waiting to be used. All this waiting can harm the battery and shorten its lifespan. Also, the added heat from the power source and overcharging are the two culprits that can cause laptop batteries to age faster..
. and im not so sure about what should i do with the battery, should i plug it in the laptop and use it once a day and then remove it and use the laptop without it or never plug it to the laptop ?

Is This A Good Question/Topic? 0

I have a laptop and its 2-3 years old. I have had it alwsy plugged in with battery and now it can be off power for 5 minutes until it shuts down. I could just buy a new battery wich will cost me prob 100 or so. 100 isn't that much for 3 years. But because technology has been going fast i decided to buy a new one anyways so i can keep up with al the software etc. I'm in the IT btw. Just use the battery but don't go crazy with it by never using it and leaving it fully charged. just use it once or twice a day and you will be just fine.

Are you on Windows? If so you can produce a detailed report from a cmd prompt:
powercfg /batteryreport /output MYFOLDER\mybatteryreport.html

Omit MYFOLDER\ and it will use the current location to create the file.

Mine says (at the bottom):

Quote

Current estimate of battery life based on all observed drains since OS install
Since OS install 3:22:55 (at full charge), 3:45:00 (at design capacity)

My battery is always inserted and I'm plugged in. (It's a couple of years old.) I do try to switch to the battery occasionally, and let it drain. Newer batteries perform better/ lose less capacity.

I unplugged a little while ago (an hour) and pointing at the battery icon it says 2hr 38m remaining. That'll do me!

i typed in:
C:\WINDOWS\system32>powercfg /batteryreport

and it gave me the result:
Battery life report saved to C:\WINDOWS\system32\battery-report.html.

i tried to launch it from cmd:
C:\WINDOWS\system32>start battery-report.html

but it started my browser (Mozilla Firefox) and i got the result: File not found, can you please tell me how to start it ?

Find the file using File Explorer (aka Windows Explorer) and double-click it.

Double-click it, or right-click and Open. It's an HTML document so will open in your Firefox browser.

I don't know why you cannot open it. It is a simple .html page and your previous screenshot shows it recognised with a Firefox icon. You could go into Firefox and use Ctrl-O to open the file. I'm at a loss otherwise. Although, I would save it somewhere other than /Windows/System32/. I ran

powercfg /batteryreport /output mybatteryreport.html

when I was in my user folder.
