I have a 6-7 yr old Acer laptop. I would like to find out just how long (approximately would be good enough) the battery will last (in continuous
use) before it would peter out when it would be used without being plugged in.
While I could simply turn it on, set all the power options to "Never" (when it would go into sleep, hibernate, etc., mode, as well as when its display would turn off), and time that out, I would like to run a more 'real world' test; and of course that would be having the hard drive in constant use.
A Google search turned up a program called "Battery Eater" (http://www.batteryeater.com/news.html), and one of its test modes is to continuously run; this test does the following: "Load Text button towards the bottom in the window and choose a text file. The Readerís Test, once activated, will open the writing file and automatically scroll in the file time and time again until your laptopís battery gives out"; and when the battery is recharged, it will have a log file of the results.
While such an 'endurance' test would give me an 'extreme' time frame as to battery life (typically my HD would not be in constant use), it would give me a worst case scenario as to what I could expect.
I'm wondering if anyone on this forum has used this program, and would like to share their perspective as how accurate it is, OR knows of some other utility type piece of software that is better suited to what I'm trying to accomplish.
Sorry, Jack, looks like you are fresh out of luck. My lappy has just reported to me that my battery may need replacing soon. Not that I use it on batteries much, anyway, so, as long as it allows me an orderly shutdown, I'm not worrying about this.
Go to ebay, and search on the battery's part number. You will find other manufacturers produce batteries at a fraction of the cost. Ditto battery
chargers if that every dies as well.
PS Why worry about battery life, just run it from the charger all the time, unless you are planning to use it in a location where there is no mains electricity. I've ran my laptops that way for a few decades now (different models at different times of course), with no problems.
I got a compatible Sony laptop battery for about £30 instead of £140 Sony wanted
