Hi,
I'm new to the forums, and I was searching around but couldn't find a simple explanation on if a 12v adapter can be converted to a charger.
What i'm trying to do is charge a 12v 7.5Ah/20h lead acid battery. At home I have a 12V 500mA 14W adapter which looks exactly like the 12V 1000mA charger at an electronics store. Minus the 500mA difference, what else could be different inside the charger that the adapter may not have?
From the outside they look exactly the same, i'm wondering what circuitry is inside beside the transformer?
I've seen all the more advanced schematics on this site with float charge and multiple stages. I'm just trying to create the most simplest of chargers for a 12V lead acid battery.
Reading all your informative posts, I realized that an adapter that says 12V is really around 14.7 - 15V which I guess is perfect for charging as the charger has to have more voltage over the battery.
Hopefully someone can answer this for me, I've seen posts stating that an adapter cannot charge batteries and some say it can, i'm totally confused at this point.
Thanks!!
