- TL;DR Summary
- I'm thinking of buying a voltage source to charge batteries instead of a dedicated charger.
I want to buy a car/motorcycle battery charger because it's a very convenient thing to have.
Also, for a while, I have wanted to have a simple power source like shown.
How safe is it to use it to charge lead-acid batteries from cars or motorcycles? I know the simplest option is to buy the specific product for that task but a power supply seems so much more versatile as long as I dial in the right limits for the voltage and current in the power source.
According to this, it's not too dangerous.
I have a couple of main concerns.
Thanks in advance.

I have a couple of main concerns.
- As the battery reaches the target voltage I assume the current will decrease. The system will not shut down completely but it will slow down. Do you think it is dangerous to take your eyes off it? The page I shared says to never leave it unattended but it feels like an overreaction as you would find in manuals so that the company cannot be considered liable. What's the risk of the charging process going wrong if the power supply is right?
- Batteries usually have cells in series or parallel depending on the purpose. Each cell is not always accessible. Should I worry about the charge not being balanced? Chargers in the market for lead batteries I've used don't seem to be concerned about this because they just have a connection to the two poles coming out of the batteries.
Thanks in advance.
