We have been using Concorde batteries in our aircraft for the last seven years. It is important to keep a float charger connected when the aircraft is not flown daily and when installing this battery in a newly purchased aircraft, we added a fused charging pigtail. After a test flight which required two starts (we had to top the tanks), the aircraft was parked and a battery minder was routinely connected. The next morning when the aircraft was going to be flown, the baterry was completely dead, despite a float charger being connected for nearly 18 hours. The battery was isolated from the electrical system and connected to a different float charger. After five days when the state of charge indicator would not indicate above 75%, a call was made to Concorde Battery to seek warranty advice. The phone was answered automatically in a coherent manner. Selecting 0 immediately was answered by a comprehendable voice who redirected the call to another person who was equally concerned with identifying our problem. A suggestion was made to take the battery to a nearby distributor for evealuation or get an RMA to have it returned to the factory. Not wanting to purchase another battery while we waited to identify if this battery was damaged beyond repair, the battery was driven to the nearest distributor. The distributor met us at their door taking the battery directly to the bench where testing revealed it was at 100% state of charge and possessed the necessary cranking amps to start an aircraft. Weve not experienced this level or qualiuty of service in recent years and delighted we chose a Concorde Battery .

The battery showed up a couple days after ordering. Came fully charged and ready to go. I thought Id have to put it on the charger over night to get it full. Working great.
