[Shop-talk] Trickle Chargers

Will the Battery Minder work on a single 6V battery or do you need at least two hooked up in series?

As I see it, they didn't have a "float" circuit at all. Just a constant
(regulated) voltage.

So did mine. But likely that was because I didn't fully charge the battery
first. They apparently have no current-limiting circuitry in them; only the
output resistance of the wall wart. Faced with the load of a discharged
battery, it eventually overheats and burns out. When I tried upgrading the
wall wart, the electronics box melted.

Interesting. I've got a few of those myself. You're talking about the
units from VDC Electronics, right ?
