Free 3.6 volt lithium battery software for linux

Wmbattery displays the status of your laptops battery in a small icon. This includes if it is plugged in, if the battery is charging, how many minutes of battery life remain, battery life remaining (with both a percentage and a graph), and battery status (high - green, low - yellow, or critical - red).
Theres nothing in the program that makes it require WindowMaker, except maybe the look. It can be docked in WindowMaker or Aftersteps dock.
Wmbattery is based heavily on wmapm by Chris D. Faulhaber.
Enhancements:
- Improved icon layout. I crammed the same information into less space while making the icon more elegant and visually pleasing (IMHO).
- Easier to drag onto dock.
- It consumes a little less memory.
- Uses only 10 colors.
- ACPI support, including multiple battery support and battery charging completion countdown timer.
- Support for getting battery status from the sonypi driver instead of APM, for some Sony laptops that do not have apm support.
- Can make its own estimatess of time remaining or time until full charge, even if APM does not.

Battery77 project is a remake of the Battle City game. Play the game right at the Battery homepage.
Looking for 2d sprite artist (designer) to redraw the tiny gfx.
Enhancements:
- Level 5 added.
- Attempt to fix socket bug.
- Players tank shot interval is 300.

Xfce 4 Battery Plugin is a battery monitor panel plugin for Xfce4, written by Nick Penwarden and Edscott Wilson Garcia, compatible with APM and ACPI, for Linux and *BSD.
Usage:
- Compile or install xfce4-battery-plugin
- Right-click the panel > Add New Items
- Add the Battery Monitor
- Right-click plugin > Properties for the properties dialog

KThinkBat is a laptop battery monitor for the KDE-Kicker. KThinkBat is inspired by the "Battery Maximizer" includes with IBM ThinkPads (now Levono).
Yes, I know, there is allready a standard battery monitor KDE-Application, but it is simply too small to realize the real battery charge at first blush.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.
Enhancements:
- Added Czech translation send by Martin Samek
- Refactored complete internal battery handling
- Introduced new abstract base class for Bat Info
- Added new Bat Info Sum class
- Fixed bug with wrong calculation remaining time when using two batteries
- Translation updates: Bulgarian (by Aleksandar Tsankov), German, Slovak (by Jozef Riha), Spanish (Luis Sobalvarro)
- Show current power consuption as current charge rate if charging
- More intelligent remaining time calculation in battery summary mode (if only one battery present, use the more accurate value from this battery instead of generic recalculation)
- Added COPYING.LIB (LGPL) and COPYING.DOC (GNU FDL) as some files are released under these licenses (thanks to Harald Sitter from Kubuntu team)

FluxBat is an ACPI based battery monitor for the fluxbox window manager. It includes two parts: a daemon process that runs the update script and the update script itself.
The whole software contains only about 100 lines of code and is easy to use by including only one line in the menu configuration file of fluxbox.
Enhancements:
- This release only forces the fluxbox menu reload if the battery state really changed.

Mint is a small X toolbar that can switch network configurations in a few keystrokes. Mint enables you to change your network configurations in a few keystrokes. It supports DHCP and static addresses, and can execute an authentication script when it changes the configuration. It also displays a clock and a battery meter.
mint displays the name of current network configuration. It also displays a clock and a battery meter. The battery meter shows the percentage of remaining battery life and appends a `+ to the battery life when AC power is connected.
Since it changes network configuration, mint must be run setuid root. It safely invokes the authentication script as the user who started mint, not root.
mint provides a network configuration called "off" to shutdown the network interface. mint displays "?" if it does not recognize the current network configuration. It displays "xx" if the network interface does not exist.
The authentication script is run in the background. When you switch network configuration, mint kills any previously running authentication script. For DHCP configurations, mint does does not run the authentication script if the DHCP request fails.
DHCP support is made by the "dhcpcd" command, which mint expects to find in /sbin. dhcpcd should have come with your Linux distribution; if not you can get it from http://www.phystech.com/download/dhcpcd.html.
Enhancements:
- The beta version of Bianca was released and is available for download. Bianca comes with two brand new themes: Bianca-Blue and Bianca-Green which give the distribution a whole new minty look. Only one panel at the bottom, a Slab-like menu, new default icons. The following applications were added to Bianca: mintMenu, a replacement for the GNOME menu; mintConfig, a Control Center application; mintDisk, a program which automatically mounts FAT32 and NTFS partitions; mintDesktop, which now comes as a package, has a graphical configuration front-end; mintWifi, which now comes as a package.

kompact0r is a simple text based system monitor. It can do everything kompact does but kompact0r displays:

- Distro (not auto detected)
- Kernel, KDE & QT version
- CPU MHz, Temp and % load graph
- Ram & Swap use
- eth0 and/or eth1 IP address and KB/s in & out w/graphs
- Uptime
- Date & Calendar

Comes with:

- Chocie of 2 backgrounds
- Thorough documentation.txt nicely written by benny fletch.

Still available in the theme if you wish to do some editing:

- User & Host names
- Battery Status
- CPU Model
- Used space on the partitions
- Time

ProcMeter is a framework on which a number of modules (plugins) are loaded. More modules can be written as required to perform more monitoring and informational functions.
The statistics that are displayed are grouped by module, with a menu allowing selection of module and a sub-menu for each output available for that module.
APM
Advanced Power Management information. These outputs are only available if you have configured the kernel to have the APM feature.
Biff
Monitors the e-mail inbox (in /var/spool/mail/username or /var/mail/username) and indicates the number of e-mails that are waiting and the size.
Date_Time
The current date and time and the amount of time since the system was last booted.
DiskUsage
Shows the percentage of the disk that is used and the amount of free space for each of the local disks that it finds are mounted or can be mounted when the program starts.
LogFile
Monitors the size and number of lines and the rate of increase of these in a set of log files.
Memory
The amount of memory that is used for programs, buffers, cache and the amount that is free.
Network
The network devices and the amount of traffic on each of them. It will automatically pick up available devices when it starts.
Processes
The load average and the number of processes running and starting.
ProcMeter
Information about the procmeter program itself.
Sensors
Hardware sensors for temperature and fan speed. (Requires sensor hardware and kernel patch from http://www.netroedge.com/~lm78/ or version 2.6 kernel).
Statistics
Low level system statistics. For example CPU usage, disk usage, swapping and paging.
VM_Statistics
Low level system statistics about virtual memory (swaping and paging) for kernel version 2.5 where the information has moved from the Statistics section.
Stat-CPU
Statistics about individual CPU usage including support for SMP machines.
Stat-Disk
Statistics about individual disk usage including support for up to 4 disks.
Stat-Intr
Statistics about individual interrupts including support for up to 32 interrupts.
Uname
The system information from the uname program, hostname and Linux kernel version.
Wireless
Information about wireless network devices. It will automatically pick up available devices when it starts.
Longrun
For systems with the Transmeta Crueso processor, information about longrun. Will not work unless the kernel is compiled with CPUID support, and /dev/cpu/0/cpuid must be readable by procmeter.
ACPI
Advanced Configuration and Power Interface information. These outputs are only available if you have enabled ACPI in the Linux kernel and you have the appropriate hardware. ACPI can report various information about a systems battery, and may also have thermal outputs available.
For each of the outputs there is a properties information window that can be used to check the meaning of an output and other properties about it.
Enhancements:
- Minor bugfixes only (increased buffer size in the df module).
