Anybody have a schematic for a 'SMART' charger .....or 3 state to give it another name for a Lead Acid Batteries.
Have battery charges and several 12V supplies ... be good to make up a SMART charger that would allow me to leave 12V Lead Acid or CA/CA on 'float' charge.
Keep an eye on Lidl and Aldi. They do them several times a year for about
13 quid. Cheaper than you could make one for. They are excellent.
Careful there Dave, you just know ALDI will pinch and attribute your sentiments to diybanter!!
Pst!! Lurking Aldi store leaflet compiling man!,
it's 'uk.d-i-y on Usenet' ;-)
lead acid can be kept on a regulated-voltage charger forever, say set at 13= .5 volts as with a car's alternator. Plus a series resistor to limit charg= e current to 14 hour charge rate. This is sometimes explained on the batte= ry cases. An exact 12v regulated supply wouldn't fully charge them, but wo= uld probably keep them in good condition.
