Review on Schumacher FR01242 Automatic Battery Maintainer by Corey Slivinsky

This charger is relatively small and very light. The first few times I tried to charge my modern car battery, the charger gave an error with a reverse polarity indicator. The manual wasn't that helpful except to suggest that the machine might still be drawing power. Which is entirely possible, as maintaining computer settings and entertainment requires some power, and I'm not going to reset everything by disconnecting the battery from the machine. However, after readjusting the battery clamps a few times, it finally worked properly and stopped charging the battery. I really miss the ammeter on my old charger that gave me a good indication of how low the battery was by showing how much current was going into the battery (although I'm not sure how well this unintelligent charger maintains the overall charge could). . car battery life).
