Simple 12 V Battery Charger Circuit Diagram
This 12 V Battery Charger Circuit Diagram is a high performance charger for gelled electrolyte lead-acid batteries. Charger quickly recharges battery and shuts off at full charge. Initially, charging current is limited to 2A. As the battery voltage rises, current to the battery decreases, and when the current has decreased to 150 mA, the charger switches to a lower float voltage preventing overcharge.
12 V Battery Charger Circuit Diagram
When the start switch is pushed, the output of the charger goes to 14 V. As the battery approaches full charge, the charging current decreases and the output voltage is reduced from 14 V to about 12 5 V terminating the charging. Transistor Ql then lights the LED as a visual indication of full charge.

6 to 12 Volt Power Supply Inverter
This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car. The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages.

Simple 12 16V Converter Wiring diagram Schematic
This is simple 12 -16V converter schema diagram . Many devices operate from a car`s 12-V electrical system. Some require 12 V; others require some lesser voltage. An automobile battery`s output can vary from 12 to 13.8 V under normal circumstances. The load requirements of the device might vary.
This schema maintains a constant voltage regardless of how those factors change. Simple schema, A, uses a 7805 voltage regulator.In addition to a constant output, this JC provides overload and short-schema protection. That unit is a 5-V, 1-A regulator, but when placed in schema B, it can provide other voltages as well. When the arm of potentiometer R1 is moved toward ground, the output varies from 5 to about 10 V.

24 W BTL or 2 x 12 W stereo car radio power amplifier
GENERAL DESCRIPTION
The TDA1510AQ is a class-B integrated output amplifier encapsulated in a 13-lead single in-line (SlL) plastic power package. Developed primarily for car radio application, the device can also be used to drive low impedance loads (down to 1,6 Ω). With a supply voltage (VP) of 14,4 V, an output power of 24 W can be delivered into a 4 Ω Bridge Tied Load (BTL), or when used as a stereo amplifier, 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.
Features
- Flexibility − stereo as well as mono BTL
- Low offset voltage at the output (important for BTL)
- Load dump protection
- A.C. short-circuit-safe to ground
- Low number, small sized external components
- Internal limiting of bandwidth for high frequencies
- High output power
- Large useable gain variation
- Good ripple rejection
- Thermal protection
- Low stand-by current possibility
- High reliability.
