Welcome to ebatterychargers.com, the weblog where we discuss about car battery chargers, cell phone, laptop or solar battery chargers, different electronic circuits diagrams and everything else that includes a battery that must be charged. Every electronic device need energy to "stay alive", some of them use batteries which needs chargers.
It's simple, all you have to do is choose the category you are interested from the top menu or scroll down, and then you'll find the information you need.
This battery voltage splitter is used where a common is needed; in many systems is to obtain positive and negative supplies from a single battery. Where current requirements are small, the circuit shown is a simple solution. It provides symmetrical +&- output voltages, both equal to one half the input voltage. The output voltages are referenced to pin 3, output common. If the input voltage between pin 8 and pin 5 exceeds 6 V, pin 6 should also be connected to pin 3, as shown by the dashed line.
This 12 Volt Battery Auto Charger circuit will quickly and easily charge most any lead acid battery. When the battery is fully charged, the circuit Relay switches off and lights a LED.
Here is the low cost universal charger circuit diagram for NiCD – NiMH batteries. This battery charger circuit is ideal for car use. It has ability to transform a mains adapter in to a charger . This one can be used to charge cellular phone, toys, portables, video batteries, MP3 players, … and has selectable charge current. An LED is located in circuit to indicate charging. Can be built on a general purpose PCB or a veroboard.
