Config+ will show \u201c(invalid)\u201d for the battery voltage. This is a measurement error of the station. As a workaround, you should use the \u201cFactory reset\u201d command in Config+. This will reset the device and should fix the voltage value.<\/p>\n<p>I opened the unit up and found that the sleeve of the battery was cracked, but that there were no visible signs of corrosion or other problems, <a href=\"http:\/\/axotron.se\/blog\/sportident-station-with-pulverized-power-pins\/\">unlike in a previous station<\/a>.
