Can You Charge A 12v Battery With A Car. Ideally slow charging your batteries is the best option. As your charger was designed for a car 12V battery it has same voltage parameters for your tiny 12V battery.
What should I do if my car battery wont charge. The charger that provides the highest number of amps per hour would be the fastest but they are not always the best. A typical battery charger at least newer ones have systems built in which will charge the battery to capacity then check it often enough to know when it needs a little something more but wont.
It can be as much as 10 years for a car battery but even so it will die eventually.
Yes a 10-watt solar panel can charge a 12V battery but the panel must be a 12V with a 10-watt specification. If you want to charge a 12 volt lead-acid car battery with a 12 volt DC power supply which is not a battery charger then no that wont work. It can be as much as 10 years for a car battery but even so it will die eventually. When charging with a LEAF it is necessary to switch-on in order to listen to radio or run heater.
