By following the URL provided by Schneider, I managed to have the battery indicator back to work on Lubuntu 15.04(upgraded from 14.10). Here are my manual installation steps of xubuntu-staging without using 'apt-get dist-upgrade:'
1. goto https://launchpad.net/~xubuntu-dev/+archive/ubuntu/xubuntu-staging/+sourcepub/5186374/+listing-archive-extra and download packages based on your architecture. For example: $ wget https://launchpad.net/~xubuntu-dev/+archive/ubuntu/xubuntu-staging/+files/xfce4-power-manager-data_1.5.2-0ubuntu1%7E15.10_all.deb $ wget https://launchpad.net/~xubuntu-dev/+archive/ubuntu/xubuntu-staging/+files/xfce4-power-manager-plugins_1.5.2-0ubuntu1%7E15.10_amd64.deb $ wget https://launchpad.net/~xubuntu-dev/+archive/ubuntu/xubuntu-staging/+files/xfce4-power-manager_1.5.2-0ubuntu1%7E15.10_amd64.deb 2. get the latest libxfce4panel-2.0. For example: $ wget http://gb.archive.ubuntu.com/ubuntu/ubuntu/ubuntu/ubuntu/pool/universe/x/xfce4-panel/libxfce4panel-2.0-4_4.12.0-3ubuntu2_amd64.deb 3. install libxfce4-ui-2-0 for one of he required dependencies: $ sudo apt-get install libxfce4ui-2-0 4. update xfce4-power-manager to 1.5.x by installing .deb files downloaded in step 1 and 2: $ sudo dpkg -i libxfce4panel-2.0-4_4.12.0-3ubuntu2_amd64.deb xfce4-power-manager-data_1.5.2-0ubuntu1~15.10_all.deb xfce4-power-manager_1.5.2-0ubuntu1~15.10_amd64.deb xfce4-power-manager-plugins_1.5.2-0ubuntu1~15.10_amd64.deb 5. run xfce4-power-manager-settings command from the command line and then check that Status notifications and System tray icon are set to ON. 6. run xfce4-power-manager --restart from the command line
