I think it was deliberate to sell batteries. It would be trivial to shut off the
charger if it saw, say, -0.6 volts at its terminals.
A car battery charger that won't charge a dead battery is idiotic at best.
Sure it is. Who wants to make sure someone doesn't try to charge a
battery with a shorted cell and start a fire?
What's going to catch fire? The battery? Some idiotic Chinese electronic charger
that doesn't current limit?
A car battery with a shorted cell can boil over and rupture. Not that
you give a damn.
If it shorts while it's fully charged, yes, but that's very rare. Car batteries
are amazingly rugged. But that's not the situation we're talking about here.
If it's already shorted and stable that way, charging current will apply zero
power to a shorted cell, so it won't "boil and rupture." I^2 * R = 0 when R = 0.
Dinky chargers don't have enough power to boil a battery anyhow.
Beside, the cheap electronic chargers would still pump current into a battery
with one zero-volt cell. They just won't put current into a battery with all
zero volt cells.
Who cares about lawsuits, or killing their customers?
Why kill them when it's more profitable to rip them off?
Sigh. They have to be idiot proof for the uneducated masses. No one
who builds battery chargers gives a damn about your problem.
They design them that way to sell to parts stores, who sell the chargers and
then sell batteries to replace the ones that "won't take a charge."
