Question about Schumacher & Fast Charge Starter Charger

Schumacker battery charger problem?

I have a Schumacker Model 1052A-PE Trickle/Battery charger/Engine start rated at 2/10/50 A.

I want to charge a 80 AH car battery. When I put the charger on the battery the following occurs:

1) No charger connected Battery Voltage = 5.62 V
2) Charger connected but not on Battery Voltage = 2.45 V
3) Charger on at 2A position Battery Voltage = 13.33 V
4) Charger on at 10A position Battery Voltage = 14.23 V
5) Charger on at 50A position Battery Voltage = 15.93 V

At any of these positions, the charger Ammeter always reads zero. It never gives a reading other than zero. The meter gives a little "bip" near zero when I change from 2A to 10A. I can always hear the transformer hum.

Am I charging the battery? I can leave the charger on over night and the battery never reads 12V.

Do I have a bad battery that won't take a charge, or a bad meter that won't indicate current or a bad battery charger?

Thank you for your help.

    Unfortunately, that's not what the manual says. It says on the 10
    A setting, the meter should start out reading 10A and then gradually
    taper off as the battery charges.

You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.

I left a 1960 sears battery charger plugeed into my fuly charged boat battery, how long before it is ruined?

should not damage the battery or the charger at all
battery chargers reduce the charge rate as the battery is charged up and it reduce to a virtual trickle charge to maintain any internal leak from a standing battery
just ensure that the electrolyte level i the battery is maintained

I left a 1960 sears battery charger plugged into my boat battery, how long before it ruins the battery, when I forgot the battery was plugged in, it was fully charged.

Hey Mike, I can't find a Sears model #1960 charger, so I don't know the specs on it. If it is a typical old school 2 / 6 amp charger or any other that does not automatically shut off or switch to trickle charging, you may be in trouble in a day or two or longer - depending on the charge rate you picked and the percentage of full charge battery was before you connected it.

Depends on what battery. car battery I charge with i 10 means with a current 1 / 10 of the capacity in Ampere hours for 14 hours. So a 80 Ah battery with 8 A for 14 hours.
A camera battery in the charger I got with the camera. Or a good universal charger from GP. A NiMH AA or AAA battery, with a quick charger that at least needs 2 hours to charge. The quick chargers I have that can charge in less than 2 hours (one can manage in 15 minutes) all kill batteries after a few charge cycles. Hope this helps.

Okay, I'm working on a scooter for my nephew that originally came with (2) 12 volt 12Ah batteries minus the charger. and I know I need to replace them with (2) batteries of the same 12 volts and lets

not exact, to charge apropiate needs 10% more than nominal voltage. if not, will not charge the batteries.
And the charger its very important because you can over charge the battery.An example,if you have a 12 Amps Batteries each one if you put it in series will be 24 parallel conection will be 12 volts but the double of Amps.
At serial connection will be 12 Volts the amps will be the same but the volts will be 24.

The charger at 12 Volts must be 13.8-14.5 DC Volts and divide the Amps in Hours.
The charger at 24 Volts must be 26-28 Volts. to charge well.

The charger for 12 amps batt example must charge 2 amps per hour at 6 hours = 12 Amps.(2 Amps Charger by 6 Hours Charging= 12 Amps.(Fully Charged.
3 Amperes Charger needs 4 Hours to charge 12 amps Batt.
5 Amperes Charger needs 2 Hours charging an a quarter
All of this is at DC Current.

ModelBC7210 does not change from trickle to fast charge

its all relitive bud _ you have to check the make of your charginging unit and make sure _ its relitive to the battery size you cant fill a battery up quicker unless you put it under pressure of a higher dc currant _ so just bump up the juice over power the batter charger

My battery died on my 1996 BMW Z3 roadster. I bought a new battery. I put it ithe car. Then I hooked up a trickle charger. Now the car won't start. Can anyone help me? Also, how can I tell if a fuse is...

can i ask why you put a trickle charge on a new battery ? also a trickle charger that is faulty will blow the ecu. its best not to use them on and vehicle from 90's and below as they were not designed to take them. modern cars have overloaders inbuilt into the ecu so lighting strikes etc don't do any damage and the engine will run on.

I have a Schumacker Model SS-51A-PE charger and was charging a boat battery when I heard a medium-to-loud pop. I checked the charger and realized there was no output. It hums quite loudly when plugged in...

Quite simply - the unit has suffered component failure - most likely more than one. Capacitors are the usual source of noisy 'bang' or 'pop' sounds, followed by diodes and bridge rectifiers. If you have some knowledge of electronics, you can attempt repair, but, if none, I suggest leaving possible repairs to someone who does.
The humming sound you hear is the transformer under stress, and, if left connected, it too will die.

When i start my bike rec tech v twin with battery charger hooked to the battery it starts no problem, if i dissconnect the charger cables it starts coughing and dies? can you please help

Sounds like you need a new battery. They only last about two years. Check to see that water is covering the plates in each cell. Use a trickle charger to charge the battery for about four hours. If the battery will not hold a charge then replace it. Please rate my answer.

I just put my battery in the bike. I went to start it up, it powered up but when I went to start it up it clicked off.

The battery has to be fully charged on a trickle charger before putting it into the bike. The charging system in a bike is small compared to a car and does not keep the battery fully charged. Therefore, it is a good idea to put a trickle charger on it when it is idle.
