If you have an electronic device that requires 12 Volt DC power but only have access to 110V AC power, you will need to convert the AC power to DC. This can be done with the use of a power supply or adapter. In this article, we will guide you through the steps on how to convert...
to work properly. One way of providing multiple voltages is by use of a voltage divider circuit. If, for example, a 12 Volt battery must supply 12 Volts of energy to one device and 6 Volts of energy to another, the voltage divider circuit can be tapped in two places to provide both ...
In theory, you can calculate the run-time for any of your battery's accessories by dividing the amp-hour rating of the battery by the amp draw of the accessory. You might have to convert from watts first. For instance, if you want to know how long you can bang a 1,000-watt stereo...
Back to the dead battery dilemma. For this article, we're talking about the 12-volt lead-acid batteries, and when one goes dead ajumpstartor battery recharge is the obvious solution. With traditional batteries, it's also just easy (but perhaps costly) to visit a local automotive parts stor...

Use a three-phase battery charger to recharge the battery. These are designed for lead acid batteries and will automatically slow charging as the battery nears full charge, preventing overcharging. Make sure the charger is turned off and connect the positive lead to the positive battery terminal ...
As various problems during the course of battery recharge, the author designs a kind of distributed recharge system of large capacity lead - acid battery, which settles the critical technology on the recharge test, and realises fast recharge. The designing thought of the system is a kind of se...
