First off you must have the same type batteries. Connect the positive post of the first battery to the positive post of the second battery. Then connect the negative post of the first battery to the negative post of the second battery. Now connect the positive post of the first battery to the positive connection on the vehicle. Then connect the negative post of the first battery to the negative cable of the vehicle. Click the link for a diagram.

Connect three 12 volt batteries in series and you will have 36 volts but will only have the amperage of one of the batteries.


For Australian made deep cycle batteries, try the related links.



You just connect them in Parallel. Two 12 volt batteries connected in parallel will output 12 volts. Two connected in Series will output 24 volts. Just connect the negative terminal on the first battery to the negative on the second battery. Then connect the positive terminal on first battery to the positive on the second battery. Connect the cables to the second battery, positive to positive and negative to negative. Click the link for a diagram.


You equalize deep cycle batteries by charging with a higher than normal voltage for a short period of time. Consult the manufacturer for details.


Deep cycle means that the battery gets almost totally drained before recharging occurs. You'd find this on batteries connected to solar panels for instance that are used at night. These batteries differ from a motorcar battery as draining a car battery completely, damages the battery. Deep cycle batteries are designed to deal with this and are usually more expensive than car batteries.


Yes if they are connected in parallel but I would not recommend it. Just charge them one at a time.


a deep cycle battery i a battery that you can charge and discharge over and over without harming the cells in the battery unlike a normal battery . deep cycle batteries are normally used in boats



automobile batteries have more number of lead plates to facilitate quick and large amount of power output during engine starting. They give large amount of power for few seconds to start the engine, not continuously, Whereas the Inverter batteries give steady power output for long time.Deep Cycle Batteries:The inverter batteries are normally called deep cycle batteries. The battery plates in such type batteries won't get damaged even in deep discharge condition. But the automobile battery is quite different from deep cycle batteries, if an automobile battery is discharged deeply, then definitely it will damage the lead plates and reduce the battery life


Most RV batteries are Deep Cycle type. Deep cycle batteries are lead-acid battery capable of being regularly discharged using most of its capacity in the process. Deep cycle batteries also have thicker plates inside the case. Normal car batteries will not discharge to the level or last as long as a deep cycle battery.As to how long it will last (lifespan) also depends on usage. Deep cycle batteries can be stored (fully charged) up to 12 months and only lose 25% of their capacity. Again depends on age of battery. Most RV's have a system where the deep cycle (RV) battery is constantly charged when the engine is running and most too will have a battery charge indicator on a control panel inside the RV itself.


Assuming neither battery is used to start the engine, simply connect the positive (+) terminal of the first battery to the positive terminal of the second battery. Then connect the negative (-) terminal of the first battery to the negative terminal of the second battery. Connect the load circuit to the positive and negative terminals of one of the batteries as usual. You may want to charge the batteries separately before making the connection, since connecting a charged battery to a discharged battery will result in a very large current flowing from the charged battery to the discharged battery, possibly damaging the wiring or either battery.


Automotive batteries are not known for their "deep cycle" capabilities. If possible, don't allow them to EVER discharge completely.


There are several battery car systems that can be considered popular because many people used them. These are the flooded cell batteries, sealed batteries, deep cycle batteries and lithium-ion batteries.


No.Although quite similar, golf cart batteries and automobile batteries are designed with different functions in mind.The automobile battery is designed to provide high current for starting, but once your car starts, the battery typically isn't required to do much except to accept a recharge.Golf cart batteries, however, are what's called a "deep cycle" battery. Deep cycle batteries typically provide lower levels of electrical current to devices for a longer time.


Golf carts run a 6 volt battery. The term "golf-cart" bettery refers to a size like GC-2or T-105 and does not tell you if it is a deep-cycle battery or not (like the type used for alternative energy applications). You don't have to have deep-cycle battery to run a golf cart, it's just a good idea. The expensive golf-cart batteries (like Trojan) are true deep-cycle baterries.


When the battery looses it charge. It is designed to be run completely down before recharging.


If the battery is not a deep cycle battery, allowing the battery to run down dead multiple times will shorten its life span.


Series three of the six batteries into group one. Series the other three remaining batteries into group two. Parallel group one and twos positives together. Parallel group one and twos negatives together. The total voltage will equal 36 volts on the paralleled positive and negative cables. If you are thinking of using these on a golf cart then forget it. Automobile batteries are not deep cell batteries as a golf cart battery is. They are not designed to be totally discharged as a deep cell battery is. They will work but will not last very long. The repeated charge and discharge will destroy the batteries in a very short time.


If the charger is a 12 volt DC machine, connect the leads to the two battery terminals that the load is taken from. Take care to note the polarity of the leads to the polarity of the battery terminals. There will be a short jumper cable between the two six volt batteries. The charger leads go on the opposite terminals of the two batteries that the jumper is connected to.


As long as the battery is functional you can continue to jump it. However, know that every time you run a car battery down you shorten its life. A battery that is designed to be run completely down and then recharged is called a deep cycle battery. Automobile batteries are not deep cycle batteries. Discharging them completely causes damage to the battery itself.


They are primarily intended- as the name suggests for Maritime occupations- we are all familiar with the use of Batteries on, for example, Submarines. Run deep indeed.


For a lead acid battery it's a deep cycle battery,these are used for RV's and boats where you may only use the vehicle a few times per year.For household batteries Panasonic makes this claim for it's EVolta alkaline batteries.


They are normally deep-cycle batteries, but otherwise there is no difference, except that batteries charged by solar power will usually also charge at a slower rate, because the energy source is usually not very great.


A deep cycle battery delivers normally between fifty and eighty percent of discharge, which means it can be challenging to use as a starting battery. In most cases these batteries should be oversized by about twenty percent to deliver comparable performance.
