How do you wire four 12 volt batteries to get 36 volts and 48amps?

Four 12V batteries may not be connected end to end to obtain 36 Volts. But four 12V batteries can be connected end to end to provide 48V and push 36 amps. The actual answer to your question suggests that you drop one 12V battery and use three, not four 12V batteries end to end to obtain 36V.


What is the difference between 12V automotive and 12V marine batteries?

without knowing exactly the types of batteries you are talking about but generally marine batteries are a higher quality battery and have higher amp hour ratings which basically means they can turn the stater for longer


What is the voltage that is carried out by automobile batteries?

Virtually all automotive batteries nowadays are nominal " 12V " batteries, but will measure up to 13.6V when fully charged.


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.


What is 12V and can be used to create a fire?

12V is probably short for 12 volts, the voltage used by regular car batteries. And since 12V can strike a spark, it can be used to start a fire.


Can you use different amps on a 24V truck with 12V batteries in series?

y not?


Can you arc weld from 12V batteries?

Barely, 24v or36v in series is better


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 ----------------------------> +


Are they 8 button cell batteries in a Energizer A23 12v battery?

Yes there sure is..


Where can I find information about 12v batteries on the Internet?

There are a large number of different kinds of 12V batteries available. You will need to be very specific before you begin looking on the internet. Places like Amazon might offer a good starting point.


What are the maximum batteries power allowed on commercial vehicles?

Voltage? There are generally three voltages on commercial vehicles: 6v (really old trucks), 24v (old diesels, because 12v starters that can crank a big engine are a recent development) and 12v. Most new trucks are 12v. As to the maximum NUMBER of batteries allowed--well, there really isn't one, but semis all have four batteries in them.


Can you use a 12V 7ah battery to replace a 12V 5ah battery?

Yes, both batteries perform the same, but the 7ah battery holds more charge.
