No, but you can charge each one individually without separating them from the series loop.

How do you change a golf cart battery wired in series?
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.
What volt battery charger do you need to buy to charge two 12 volt batteries ran in series?
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.
How many AMPS will a 10 AMP 12 volt charger charge a 36 volt three battery in series system with?
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.
Can 12 volt charger charge 3 batteries wired in series?
No, if they are wired in series you have 36 volts assuming each battery is a 12 volt battery. They will have to be wired in parallel to output 12 volts. In that case you can charge them with a 12 volt charger but it will take 3 times as long as charging just one 12 volt battery.
Can you charge two 12 volt batteries wired in series without disconnecting them with a 12 volt 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.
Can you charge two 6v batteries in a series with a 12v charger and which posts do you connect the charger to?
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.
How do you connect a 24 volt charger to two 12 volt batteries?
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.
Can you charge a 12 volt battery with a 24 volt charger?
I can if I charge 2 of them at a time. Most 24 volt chargers also have a 12 volt setting. What is hard to find is a 32 volt charger. We can charge a 12V battery with 24V charger, by connecting two 12V batteries in series i. e. the negative terminal of the first battery is connected to the positive terminal of the second, now the charger positive terminal is connected to the first battery positive terminal and the negative terminal of the charger is connected to the negative terminal of the second battery.
Can you use a 3.5 amp charger to charge a 12 volt battery?
You can charge a 12 volt battery with a 6 AMP charger. The amount of amps put out by the charger is actually the rate which the power flows out from the charger, not the amount of volts it will charge. Volts and Amps are two different things. You can't charge up a 12 volt battery all the way, using a 6 volt charger. You can charge a 12 volt battery with a 12 volt charger rated at '6 amps'. It will charge the battery faster than a 2 amp charger will, but it will take longer than using a 12 amp charger. You probably don't want to use anything higher than a 12-16 amp charger for charging a 12 volt battery. Some chargers are equipped with a 60amp boost charge that is used for starting the vehicle, without having much of a charge in the battery. You DO NOT want to attempt charging a battery with it set to a 60amp boost charge. That is for starting vehicles only and could damage your battery. Keep in mind that the lower the amps are, that you use to charge the battery (1-2amps), will result in the charge lasting longer without recharging it, than if it was charged up at a higher setting (12-16amps).
How do you charge two 12V batteries in series?
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.
Can you charge batteries in series with 2 separate chargers in parallel?
Not in parallel NO - unless each charger is twice the voltage required for a single battery. For example if you had 2 x 12V batteries and placed the in series, you would have a 24V battery. If you had two 12v chargers and put then in PARALLEL with each other, you would then have a 12v charger with double the current handling. Of course if the chargers were 24v ones, then it would work fine. if you have 2 x 12v batteries (for example) and wished to charge them with separate chargers (actually quite a good idea), then each charger would be over each battery. So the batteries would be in series, the chargers would also effectively be in series too. Basically another way of looking at it would be two have a 12v battery with a 12v charger to your left and then on the right another 12v battery with a 12v charger on it. Yes you can connect the two together in series. The only slight caveat is that the chargers must be isolated from each other - and not for example a "dual output charger" which simply has an extra pair of leads but a shared charging system. - 12v + - 12v + ---------+-BATTERY---+----------+--BATTERY--+-------- - | |+ - | | + |=CHARGER=| |=CHARGER=| - <------------------------------- 24 v ----------------------------> +
How do you charge two batteries same time?
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.
