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.
What else can I help you with?
How can two batteries be connected in series to create a circuit?
To connect two batteries in series, you would connect the positive terminal of one battery to the negative terminal of the other battery. This creates a circuit where the voltage of the batteries adds up, providing a higher total voltage for the circuit.
What 2 ways that electrical charge can be produced?
Electrical charge can be produced through friction, where two objects rub together causing the transfer of electrons. Additionally, electrical charge can also be produced through contact, where two objects touch and electrons transfer from one to the other.
Why do batteries always have two terminals labeled?
Batteries have two terminals labeled because they need both a positive and a negative connection to create an electrical circuit and allow the flow of electricity.
What is the charge of a neutron in helium?
Neutrons have no charge, so in a helium atom, the neutron would also have no charge. Helium typically has two protons (+1 charge each) and two neutrons (no charge), resulting in a neutral overall charge.
What is the difference between a re chargeable and non-rechargeable battery?
yes there is. There are a few differences between the two. Some are than lithium ion batteries are rechargable whilst lithium batteries cannot be recharged. Also lithium batteries use lithium in pure forms whilst lithium ion batteries use lithium compounds to produce their charge. Lithium batteries can be seen in items like watches. An example of a lithium ion battery is a mobile phone battery.
Explain why a 24v system that runs off of 4 batteries which includes a 12v feed- that's powered by two of the batteries are getting no charge from the alternator.. the other two are charged well.?
With the batteries in series, the alternator provides the same current, and therefore the same charge to all the batteries. The alternator can take no account of any current being drawn from the 12V take off point. Part of the charge current is being fed to the 12V load and not to the batteries. Therefore, the 12-24V batteries are being fully charged while the 0-12V batteries are being partially charged. Over a period of time, the difference between the charge levels will become more obvious.
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 ----------------------------> +
What is the effect of a series circuit?
multiplies source voltage, two 12v dc batteries in series become a 24v circuit; also multiplies resistence
What is two batteries in a circuit called?
If the batteries are connected from + (positive) to - (negative) then the batteries are connected in "series". If the batteries are AA (1.5v each), then the resulting voltage of the two connected in series will be 3.0v. If the batteries are connected + to + and - to -, then they are connected in "parallel" and for the same batteries the voltage would be 1.5v, but would last twice as long as one battery by itself. A truck battery system is two 12v batteries connected in series (+ to -) to give the truck a running power of 24v.
How do you connect neon lights to two 6v batteries?
you want to wire the batteries in series...connect negative of one battery to positive of the other. You then use the two remaining terminals as youe - and + 12v source
How do you charge two 12 volt batteries with a 24 volt charger?
The two batteries can be wired in series BUT unless they are identical batteries in an identical state of charge they should be checked regularly to see if one of them is fully charged (the voltage has risen to 14.5 volts).
How many volts does it take to charge two 12 volt batteries ran in series?
24 Volts.
If a circuit has two AA alkaline batteries how many joules of energy does each coulomb of charge?
You need to multiply the number of coulombs by the number of volts. If the two batteries are in series, then you can add the voltage of both batteries.
How do you connect a 12 volt winch to 24 volt system?
Connect the 12V winch to one battery, assuming the 24V system has two batteries, connected in series.
When you charge two 6 volt batteries in series is the charger switched to 6 or 12 volt position?
Two six volt batteries in series makes 12 volts so switch the charger to the 12 volt position.
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.
When a three light circuit is connected in series with 2 6V batteries what is the voltage across each of the lights?
If a three light circuit is connected in series with two 6V batteries, and the three lights are identical, the voltage across each of the lights is 12V divided by 3, or 4V.
