16hv785: Programmable Lead Acid Battery Charger -  Microchip Application Note Published 26-Jan-06  (app note added 2/06)
A Simple Car Battery Charger psimages -  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....(added 10/05)
AN1015: 16hv785: Programmable Lead Acid Battery Charger -  Microchip Application Note Published 26-Jan-06  (app note added 2/06)
AN626: Lead Acid Battery Charger using the PIC14c000 -  Microchip Application Note Published 26-Aug-97  (app note added 2/06)
Auto batteries charger (Pd) -  ….(design added 08/08) [Site is under construction right now]

Automatic 12V Lead-Acid Battery Charger - schematic only, no circuit description at this time...[Circuit Designed by Andrew R. Morris]
Automatic Charger for Battery Operated Hi-Fi Preamps -  (electronic circuit added 7/03)
Automatic Trickle Charger -  Here is the schematic for the automatic charger I have been using for my kids' battery cars. The charger is a small molded unit that probably doesn't supply more than an amp and this circuit would have trouble with much more. No current limit is provided by this circuit - it relies on the charger for that. The circuit could be modified to provide more current by....scroll to find this one.... [from Charles Wentzel's web site]

Battery charger (Seiichi Inoue) -  This project is not so important for those who ride a car every day. In my case, a car is not used every day. In that case, the voltage of a battery is falling and a car sometimes cannot be put into operation.….(added 04/05/06)
Battery Monitor for 12V Lead-Acid -  This simple circuit makes it posible to monitor the charging process to a higher level. If you need more information then check out the LM3914 Datasheet.
Final adjustsments are simple and the only thing needed is a digital voltmeter for the necessary accuracy.…. [Jan Hamer's circuit]
Car Battery Charger -  quickly and easily charge most any lead acid battery, automatically turns charging off when ready…. [Design by Aaron Cake]
Car-Battery Charger -  An SCR Design with a 10 Amp rating.  ….(design added 12/08)
Charge indicator gauges lead-acid batteries -  05/27/99 EDN-Design Ideas  Although rechargeable, sealed lead-acid cells are uncommon in portable  applications, they are a good choice for standby applications, such as emergency lighting and burglar alarms. A key advantage…PDF has several circuits, please scroll to find this one…. [Design Idea by Fran Hoffart, Linear Technology Corp, Milpitas, CA]
Charge Monitor for 12 Volt Rechargeable Lead Acid Battery -  (circuit / schematic design added 6/06)
Charger for Gel Lead Acid Batteries -  This high-performance circuit first quickly starts (Tony van Roon's and holds) the charge at 2 amp, but as the voltage rises the current will consequently decrease.  When the current falls below 150mA, the charger automatically switches to a lower 'Float' voltage to prevent overcharging. At the point that a full charge is reached, Q1 will bias and the LED will light…. [Tony van Roon's circuit]
