does any body has charger for 12v 7ah sealed lead acid battery charger with over charging and low voltage prevention.
 

charger circuits using lm317 for 12v/7ah

the simple charger is using lm317 with constant volt abt 13.8 to 14.1 volt . in lm317 the current is limited by 1.5A.
 
Dear freind I have the circuit for the constant current and 13.6 v charger with over charging protector and deep discharging protector(9.1v) with CHARGE control and load protection when charging the battery

Check this out - **broken link removed** - just follow exactly the calibration procedure and it will work perfectly. I know because i built one, i'm using it to charge my 12v 7ah SLA battery. I hope it suits your needs and good luck

If the Voltage being applied can be controlled (13.8v - 14.2V), what will happen if I try to charge 7Ah battery with unregulated current (constant) source of 4A ?
Please clarify this point as I have a simple SMPS with this configuration.
 

sorry for not here around for such a long time.... yes off course you can lower the current by Vr2.
