What kind of battery charger ?

I brought a Ansmann ALCS2-24A' auto voltage detacts charger from a
shop " Element 14". I encounter a problem. My 6 volt 10A lead acid
battery at its weakest measure 3.59 volt when I connected to this
charger which indicate it tobe 2 volt value instead of 6 volt. I
I assumed the issue was problem with the charger and brought a 2nd one
with same brand and model. At testing counter in the shop , the same
problem occurs the 2 volt indicate instead of 6 volt. I try some other
charger with the same battery with float charge for 3-5 mins than to
the ansmann charger, It now auto detected the voltage was 6 volt and
charging the battery.
Is this a design problem with the Ansmann charger ? Thanks for members
advice .

** You need to connect a load to the battery when testing the voltage.

A 6 volt lamp would be good.

See what you get then.

3.59 volts is a VERY discharged 6 volt battery and should not be
allowed to happen, anything below 6.0 volts needs a charge.
The charger detected the battery as less then a 6 volt battery and the
only lower setting was 2 volts.
You saw for yourself that with some charge to raise the voltage the
automatic charger then detected it as a 6 volt battery and proceed to
charge it.
Without being able to find the specs of your charger it would apeear
that its operation is quite correct.

The fault is in the battery, not the charger. A 6 volt lead acid
battery should never be allowed to drop below 5.25 volts. Your
battery voltage was too low for the charger to recognize it as a
6 volt battery - not the charger's fault.

Your 6V battery is dead if its reading 3.59 volts. Get a new one.

A car battery that's completely discharged, a fraction of a volt
across its terminals, can be fully recharged and will work fine. But a
lot of modern chargers will refuse to put current into it. I'm not
sure why. You need a power suply or an old fashioned
transformer-rectifier charger to bring up a dead battery.

I recently had to kluge a charger from an old 24 volt wall-wart and a
ballast resistor. I used a power sander as the resistor. Once it got
to 8 volts or so, an electronic charger was willing to take over.
Worked fine after that.

I don't doubt you can raise the EMF but the capacity and internal
resistance are ruined by the sulphation.

Sulphation results from a battery standing around, discharged, for
months. If a battery is drained dead by something like lights being
left on, and recharged soon, it will be OK. But a lot of chargers will
refuse to charge it, so you take it back to the same auto parts store
that sold you the charger, and they *will* tell you that it can't be
charged. And they will sell you a new battery. And charge you to
dispose of the "dead" one to boot.

People jump dead cars all the time, and that works too.

Definitely. I had a dead short to the body through a 15 foot piece
of AWG 8. The battery was down to 2 volts when I found it. My battery
charger is home brew. A variac, a 30V CT 15 A transformer and a pair of
diodes. I set the charge to 5 A, and reset it every 15 minutes till it
was up to 12 volts. Then I started the truck to finish the charge. I
drove the truck with that battery for four more years.

I had a kind of opposite experience years ago with a 3.6V NiCd
battery for a cordless phone. In those days, there was no local
source of such a battery. The internal resistance was so high
that a normal charger couldn't put in any useful charge. So, just
for the heck of it, I tried coaxing it with my home-built
constant current supply. I'd built the supply earlier for testing
LEDs, zeners, etc and it could be set to give 0.5-15 mA at up to
45V. To limit the terminal voltage and the resulting battery
dissipation, I started out with a low current and gradually
increased it as the voltage went down. When it had gone down
sufficiently, I let the phone's own charger take over. At first I
was skeptical about the result, but the owner used that same
battery for years afterwards.

To try stop 12V chargers running into 6V battery, or reversed battery.

A good charger might have an over ride for that, pushbutton start?

You'd be surprised how many ways people can damage chargers and lead acid
batteries :)

You're right about temporarily flattened batteries, does some damage but no
instant kill -- sulphation takes long term undercharge to develop, like lots
of short car trips.

You need a power suply or an old fashioned
transformer-rectifier charger to bring up a dead battery.

Sounds right for common chargers. Battery voltage should come up very
quickly, a flat but not sulphated battery accepts current, flat battery
that is not accepting current is sulphated, takes some work to restore,
usually can't be, another 'it depends'...

A charger could be smart enough to charge any battery, 6 or 12 volts.
Or it could have a switch. Are there any 6 volt batteries still

I keep a Lascar power supply around now. That will push enough current
into a battery overnight to get a car to start.

A car battery that's completely discharged, a fraction of a volt
across its terminals, can be fully recharged and will work fine. But a
lot of modern chargers will refuse to put current into it. I'm not
sure why.

To try stop 12V chargers running into 6V battery, or reversed battery.

Or to sell people new batteries. "That battery won't charge" means "it
won't charge with the charger I just sold you."

A charger could be smart enough to charge any battery, 6 or 12 volts.
Or it could have a switch. Are there any 6 volt batteries still
around?

Some old tractors still use 6 volt batteries. I think I can buy them
up the road at Java Farm Supply.

I heard a report on NPR this morning that no technology ever goes
extinct.

Slave-rowed warships.
