I alway standby charge 12V 45Ah battery 1 time a month with 14V 5A source, it well ?

oh, my bad! ThanksCharging Just One Time a Month is a Cyclic Charge.
this is what ive been looking for but im going to change it up a bit to charge single cell 2vdc lead acid deep cycle cells or make it an adjustable voltage charger...thanks for posting...Here is a Schematic for a charger. It also includes a Diode to Prevent Reverse Battery Discharge.
And Formulas to calculate the Output Current and Voltage.

Your post just made my day.....Rather than SIMULATING these Circuits, Why don't you just BUILD THEM?
Then you might want to start a thread about building a bench supply. Start with what voltage and current it has to provide, how many outputs, etc. And BTW: using chips like LM317 is a poor way to build a bench supply. It is not that difficult to build one with adjustable voltage and current using cheap op-amps and transistors.I am going to make a bench power supply so that current is not fixed.

Why do you think it's a poor way?And BTW: using chips like LM317 is a poor way to build a bench supply. It is not that difficult to build one with adjustable voltage and current using cheap op-amps and transistors.
Why do you think it's a poor way?
Certainly building one with op amps and transistors is significantly more complicated.
An LM317 regulator is cheap, has a built-in reference, current limit, and over-temperature limit -- it's near bullet proof.
The only limitation is that it won't go below 1.2V but not many applications require a voltage below that level.
Here is the post I replied to:Crutschow, I Agree and if all you need is a Simple Battery Charger, Why get complicated.
Please see post ten in the thread. Building a lab supply is not that complicated. The design I posted has a lot of features which can be omitted, but the basics of voltage control loop and current control is shown.

...and then, when the circuit doesn't work, you can enter it into the simulator so that it can show you why it doesn't work...chemelec said: ↑

Yes some circuits will simulate but not work when built, but it's rare for a circuit to not simulate correctly (other than simulator problems such as convergence issues) but still work in practice.And I have found that some circuits that Simulate correctly, don't work in real life.
And Visa Versa.

This Just Depends on your SKILLS
Click on the "oh yeah" link, count down to post 10 in that thread and the schematic I posted shows how to build a bench supply.What post ten?
