Yes you can. Connect the chargers positive lead to the positive of one battery, then the negative side of that battery to the positive side of the other battery, then connect the negative lead of the charger to the negative of the second battery. Double check all your connections and turn on the charger.
No, since in series they are 24 volts so you need to charge each one independently with the 12 volt charger. This may be done disconnected or leave them connected and put the charger on the + - of the same battery.
It is important for solar battery charger output voltage to match voltage of battery system being charged. Voltage is additive in series circuits, therefore 3 12VDC solar battery chargers connected in series would provide correct output to charge a 36VDC system.
Connect the two batteries for the voltage needed. If they are 12 volt batteries and the lights are 12 volts, connect the batteries in parallel (negative to negative and positive to positive). If they are 12 volt batteries and the lights are 24 volts, connect the batteries in series (negative of one battery to positive of the other). Run a wire from batteries to first switch, then to two of the lights and the other switch (in parallel). From the second switch run a wire to the third light, then connect all three lights back to the battery.
depends on the voltage of the batteries.. four 12 volt car batteries would output 4x12 = 48 v
You must hook them up in series. You will need four 12 volt batteries to do this.
You cannot do this. If it were a 36 volt charger you could connect three 12 volt batteries in series and charge all 3 at the same time. But this is a 32 volt charger which I have never heard of.
You would need a 24 volt charger. Connect them in parallel and you can charge them both with a 12 volt charger. Or disconnect them and charge each one separately.
Use a special charger, such as an RV or boat charger, that has multiple outputs (best). Connect the two batteries in series, and use a 24V charger (ok, if the two batts are exactly the same). Connect the two batteries in parallel and use a standard 12V charger ( worst choice, one battery tends to hog the current, and they receive unequal charges). See the links for a dual-output charger I Googled.
Two six volt batteries in series makes 12 volts so switch the charger to the 12 volt position.
I think they mean "How do you charge a golf cart battery wired in series?" If you only have a 12 volt charger disconnect the batteries and charge individually. Wired in series you double the voltage, two 12 v batteries equal 24 v, three equals 36, four batteries equal 48v. Unless you have a charger that will charge the total voltage you have to charge each battery.
You can try to charge two 12 V batteries at the same time . Using a series circuit, place both batteries next one to another, and connect the negative pole of one of them to the positive pole of the other. Then use the remained poles to connect to the charger. The only other way possible, is to change the transformer, but this would be as expensive as buying another charger.
To charge two 12 volt batteries in series you'd need a 24 volt charger. That's the pat answer. You need to overcome the total voltage of the series batteries (12 V + 12 V = 24 V) to drive electrons "back into" the batteries to restore the charge. It may work better to use a 12 volt charger and just disconnect the link between the batteries and charge them in parallel, but the setup may not support separating the batteries that way. You do have the option of charging them one at a time without disconnecting anything using that 12 volt charger we mentioned. Clip the charger across one battery, charge it up, then repeat with the other battery. The two basic choices are getting an appropriate 24 volt charger or doing a bit of disconnecting and reconnecting so that the batteries can be charged in parallel with a 12 volt charger, which is a much more commonly available and less expensive charger. That's excellent advice from Quirkeyquantummechanic and well said I might add. I'm in Australia and use 2X12 volt batteries to run my 24 volt Motorguide Trolling motor. You can make disconnecting or reconnecting a lot easier when charging your 2x12volt batteries, needed to be run in series to produce 24 volts, by connecting an Anderson plug to suit. Connect the Anderson plug in a handy position into the short lead that goes from the positive post of battery1 - to the negative post of battery 2 - I.E. the lead that enables the batteries to run in series. Then simply add an isolator switch and turn the two batteries off before charging each one singularly with your 12 volt charger. Regards.
You connect the batteries in series Red charger lead to one red battery terminal, then the black battery terminal of that battery to the red battery terminal of the second battery. Then black battery terminal of the second battery to the black lead of the charger.
A 10 amp charge will only output 10 amps and 12 volts. So, if you want to charge thee 12 volt batteries hooked in series you will have to disconnect the positive cable from each battery and charge then individually. You cannot charge three 12 volt batteries hooked in series. That requires a 36 volt charger.
No, but you can charge each one individually without separating them from the series loop.
You will need two 6 volt batteries to do this. Attach a jumper wire from the negative post on one battery to the positive post on the other. Connect the remaining pos and neg posts to the battery charger.
No, since in series they are 24 volts so you need to charge each one independently with the 12 volt charger. This may be done disconnected or leave them connected and put the charger on the + - of the same battery.
