Hello everyone.. I have been researching and buying electronic tools and supplies for about 9 months now.. and this will be my first real project
What I have are a lot of sla batteries used in my rack-mounted UPS devices. I need a nice method of charging them before they go bad. I also have new sla batteries which I want to use in portable led lattern projects

Can someone take a look and see if this one is worth it? I have all the components but was rereading it tonight and saw the following which stopped me in my shoes (If this isn't a good design, have a suggestion for a better design/source?

Thanks in advanceThe circuit is actually a half-wave rectifier. It only charges the battery on every half cycle. The plug pack doesn't like this as it leaves residual flux in the core of the transformer and causes it to overheat. But that's the only drawback with the circuit.
