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.

∙ 13y agoTo charge two 12 volt batteries connected in series you will need a 24 volt charger as you now have a 24 volt battery pack. If you connect them in parallel you still only have 12 volts but double the amps so you can charge that pack with a 12 volt charger.

∙ 12y agoA 24 volt charger can charge two 12 volt batteries. The leads of the charger are connected across the two cables that leave the batteries going to the load. There will be a jumper between the batteries. Make sure that the charger leads are never connected anywhere on this jumper cable.

A circuit contains two 1.5 volt batteries and a bulb with resistance of 3 ohms calculate the current?
If the batteries are placed in series then your current would be 1 amp, if the batteries were in parallel then 0.5 amps. Voltage is common in parallel and additive in series. 1.5v + 1.5v = 3v (series) / 3 ohms = 1amp 1.5v (parallel) / 3 ohms = 0.5amps Current = Voltage divided by Resistance
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.
What are two types of electric charge?
Electric charge comes in two types, called positive and negative.
Does alpha have zero mass and zero charge?
An alpha particle is a helium nucleus. It consists of two protons and two neutrons so it has mass (approximately the same as the mass of a helium atom) and charge (a plus two charge because each proton has a charge of plus one and the neutrons are not charged).
How long should you recharge your cell battery for?
Depending on how old the phone is, it might even be impossible to change the battery at all. Almost all smart phones have batteries that are built in and cannot be exchanged. So if the battery is dead, the phone is dead and needs to be replaced. Cell phones that are no older than five years usually have batteries that hold around two years. Older batteries normally hold for life, if handled with care.
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 wire two 12 volt marine batteries together to run a 24 volt trolling motor?
To get 24v from two 12v batteries you just link between ones positive and the others negative then connect your motor to the spare terminals, but your 12v charging system will not charge them (and any 12v equipment connected to them will burn out!) without removing the link.
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.
Can I replace three 8 volt batteries with two 12 volt deep cycle marine batteries in golf cart.?
it should work as long as the batteries are connected in series + to - what you would need to check is if the charger for the cart charges 24v or 8v if it is 8v you would need to get a 24v charger for it it would be possible to charge the batteries with a 12v charger but it would need to be hooked to each battery separately
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.
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 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.
