Using the Ctek that came with the ZL1 (part of the dealer order) to charge my dying Accord battery.

For the second time, a separate Schumacher battery charger with automatic maintain mode once charged failed to maintain. I trashed my last one because I figured I had dropped it too many times. This one is older but wasn't used much, and a bigger, higher quality one with 80 amp start mode(think it was $140 10 years ago, got it cheap at sears clearance ), and again, it charged to 100% and then seemed to just kill the battery. It said 12.5 volts and 100% charge, I reset it and it immediately read 11.1 volts and 10% charged(confirmed with my voltmeter). So I do not recommend the Schumacher speedchargers. Mine had an 80 amp(start), 20 amp(charge), 10 amp and 2 amp mode. My kill a watt shows it was drawing 100 watts in its failed maintain mode, so if you have one, I wouldn't trust it. Had the same thing happen with an old 20 amp max one.

I have a noco 1 amp on each Camaro, but thinking about the 4 or 6 amp gooloo maintainer for my daily since they don't have as much down time.to be refreshed
