Review on 🔋 Schumacher 15 Amp/3 Amp Fully Automatic Battery Charger and Maintainer for Marine and Automotive Batteries - 6V/12V by Charles Adelaja

lightweight and foolproof. Some people have complained that it won't charge a completely dead battery. This is a security feature, so it cannot be turned on. when nothing is connected to it. To charge a dead battery you need to precharge it a bit to get about 1 volt so the charger knows it actually has something connected to it. To do this: 1. Unplug the charger from the wall2. Connect the battery to the charger 3. Simultaneously press and hold the "Display” and "Type” buttons 4. while holding these buttons - connect the charger to the wall. * This will bypass the security features and charge the battery even if it is low (assuming the battery can be charged at all) - Do not work in this mode for more than 5 minutes or you may damage the device and the battery. - This charges the battery sufficiently for the charger to recognize the connected battery (1 volt). 5. Unplug the charger from the wall.6. Wait 30 seconds and plug the charger into an outlet. This will return it to "normal" mode and start loading the dough properly. Much luck! brad
