16hv785: Programmable Lead Acid Battery Charger: Microchip Application Note Published 26-Jan-06 (app note added 2/06)

A Simple Car Battery Charger: This very simple circuit uses a transformer ,two diodes , a capacitor and an ammeter. To charge a battery just connect + and terminals of circuit to corresponding terminals of battery. When battery is not charged, ammeter reading shows 1-3 amps. When battery is fully charged ammeter reads Zero or nearly zero, after which battery should be removed from charger. The circuit is a full wave rectifier using 2 diodes for rectification. The capacitor is used for smoothing. I think circuit works fine without capacitor since battery itself acts a BIG capacitor. But when you are using circuit to supply 12V (as a battery eliminator) capacitor needs to be present. Care should be taken NOT to reverse + and terminals while connecting it to battery.

Charge Monitor for 12 Volt Rechargeable Lead Acid Battery: (circuit / schematic design added 6/06)

Charge Monitor for 12V lead acid battery.: A battery is a vital element of any battery-backed system. In many cases battery is more expensive than system it is backing up. Hence we need to adopt all practical measures to conserve battery life. As per manufacturer's data sheets, a 12V rechargeable lead-acid battery should be operated within 10. IV and 13.8V. When battery charges higher than 13.8V it is said to be overcharged, and when it discharges below 10.IV it can be deeply discharged. A single event of overcharge or deep discharge can bring down … (added 6/06)

Charger Selects between Full and Trickle Charge: 06/18/98 EDN Design Ideas --(added 4/02)

Circuit Charges Lead Acid Batteries: 02/03/97 EDN Design Ideas / (added 5/02) The circuit in Figure 1 charges lead-acid batteries in the conventional way: A current-limited power supply maintains a constant voltage across the battery (2.4V/cell or so, as specified by the battery manufacturer) until the charging current decreases below a certain level (also specified by the manufacturer but typically 0.01C). Normally, C represents the battery's capacity in coulombs. However, in this context, C is a rate in coulombs per second (amperes) that is numerically equal to C....
