I had two of the original model, 1.5A, wall wart design. Lost them both, not to failure, but friends/family!
I just purchased two CTEK models, the .8 A and the 4.3 A.
I like the CTEK connector better, I put the pigtail connectors on all three cars and my generator. makes it easy to disconnect.
The CTEK is not a wall wart design, it has a line cord and a battery cord.
I also have both of those CTEK models (.8a for the motorcycle - 4.3 for other needs) and never an issue.
I had a BatteryMinder before (think it was a 12248) and would have it on an AGM battery. But every time we had a power outage or a power sag I'd find afterwards on the Gel setting. Seems it didn't have the memory to come back on from last setting, or I had a faulty unit.
