I decided this morning that I would look for a battery meter for my HP Pavilion tx1410us Vista Home Premium SP2 notebook, as the Vista built-in does not show the remaining time, only the percentage of charge remaining.
My requirements were that it be freeware / open source, and that it provide a read out of the estimated time remaining.
I went to Gizmo’s freeware and searched for battery. http://www.techsupportalert.com/search/node/battery
The first result was .
The recommendation was:
“So, here’s an excellent dedicated free Battery Meter: BatteryBar !
The free version is pre-configured, but still has most/all information one needs.
Pass the mouse over the little display and you’ll see all data it
keeps track of. Click on it and it changes from % remaining to
hours:minutes remaining, all this in a color bar : green, yellow and
red. When it’s blue, battery is charging.
I followed the link, read the information there, checked what others had to say by searching in Google, and downloaded BatteryBar v3.3.3 Free . I scanned the downloaded file with my anti-virus software, and installed it once it showed clear. (System requirements say XP, Vista and Windows 7 supported, both 32bit and 64bit.)
Once installed it showed up as a toolbar showing the percentage of charge left , then when clicked toggled to show time remaining , just what I was looking for.
Also, when I hover over the toolbar with the mouse, more detailed information is shown such as the capacity, charge rate, and battery wear.
There is a “Pro” version, but this does just what I wanted, so I see no need to upgrade.
