Is there any value in older automotive battery chargers?

I bet there are people who could even repurposed those chargers and build in some automated functionality into them. Perhaps since they can have more tolerance to how discharged the battery may be (eg. below 10v for 12v battery for example) one could build a more robust automated charge/discharge tool if you have the know how to do so.

6 Frequently Asked Questions about “Old style charger battery installation”

How do you charge a dead battery?

Find one of those old little black power supplies [wall wart] for a cordless phone or some other device, you may be able to start charging a dead battery with one of those. One that puts out between 10 - 18 volts D.C. is ideal. Adapt the wires to the battery clamps of your smart charger and let it charge for a day or so.

Can a battery charger be used as a DC supply?

The output voltage will be very dependent on the load current. Using a repaired battery charger as a DC supply is quite reasonable. Certainly I would replace the selenium rectifiers with adequately rated silicon diodes, maybe adding some heat sinking.

Can a battery charger be used as a benchtop power supply?

As it's build, the charger isn't all that great. It will keep charging a battery up to 16V, or maybe even 17V without any kind of limitation other than waiting for the battery to match the output voltage. So I think instead of just refurbishing it, I'll convert it into a benchtop power supply.

Can a new battery charger see a run down battery?

The new battery chargers can't "see" a battery if it's very run down. Especially a run down agm battery. I need one that will bring those ones back up. I don't have any experience with this charger, but it seems to be a "manual" charger. It is from Harbor Freight, so there's that.

Can a 12V simple charger be used as a bench DC supply?

If you are going to use it as a bench DC supply, with updated rectifiers, you should be aware that the older type of 12V simple charger use the forward resistance of the rectifiers plus the resistance of the transformer secondary winding to limit the current. The output voltage will be very dependent on the load current.

How does a battery charger work?

Some chargers switch the primary feed to select the output voltage, others have switched connections on a small circuit board that seems to include either a transistor or some arrangement to select secondary taps. One of them got a Variac to adjust the transformer output, and terminal posts, along with a filter capacitor.
