Replacement Cells for Battery
installed in panel for 10+ years with battery
installed. Yep, the battery
appears to be toast and won't take a charge. When connected to the Garmin wall adapter/charger, the unit functions properly but won't take a charge... sometimes displays "battery missing" and sometimes after a few minutes of "Battery Charging" the unit displays "Charge Error". Opened up the battery
pack and sure enough, 3 of the 6 cells measured <.2volts.
A replacement battery
pack is $200 so it seemed prudent to at least search for availability of replacement cells. Found a match for all specs: BatterySpace.com
