Car batteries do not provide power for the car to run, the role of car batteries is to start the engine, in the use of the car first by the battery to provide a high power current to make the engine run, and then the car began to use the oil as a power for the whole car to generate electricity, and at the same time replenish the power of the car battery.
Compared to the car battery, the marine battery has more uses, firstly the marine battery also provides power for the engine to make the engine run, secondly when the engine is running, it focuses on the generation of power, and the other power needs on the boat are supplied by the battery.
(1) the depth of discharge, due to the use of different car batteries and marine batteries have different depths of discharge, only used for a single car start car batteries do not need to deep cycle, just to maintain a healthy amount of electricity can be, but also can extend the life of the battery. Marine batteries also need to be used for equipment power supply, so deep cycle is needed to improve battery capacity to ensure the normal operation of the equipment.
(2) safety, for car battery installation is not sealed need to often add distilled water, so car batteries often occur terminal corrosion, electrolyte leakage, but marine batteries in order to cope with the more demanding water environment battery sealing and hardness is higher, will not corrosion leakage and other failures. At the same time, due to the bumps in the sea, marine batteries have a strong seismic performance, usually more than ten times the car battery.
(3) Price, marine batteries are better than car batteries, but also higher prices, marine batteries are designed specifically for the boat in many aspects of the design have been optimized.
(4) construction is different, because the battery is used in different environments on the battery requirements are different, in order to adapt to the water environment, in the marine battery for lead-acid batteries when the thickness of the lead plate is higher, can cope with unexpected situations still maintain the normal use of equipment.
(5) more than one type, the use of different ways to make the car battery is only liquid-rich lead-acid batteries, while the marine battery can have lithium batteries and lead-acid batteries can also be mixed, on the one hand, in order to start on the other hand, in order to power the equipment, the two types of batteries were used just to meet this point.
(1) First of all, the two different batteries are lead-acid batteries, in the same voltage marine batteries can theoretically be used by the car, we also have to consider other aspects of the car battery to match the size of the marine battery.
(2) The most important thing is cost-effective, the car battery is only used to start the electric motor, and can not play the full role of the marine battery but also more price, do not meet the cost-effective, so we do not give the marine battery to automotive use.
(3) CCA, in the weather is too cold when the water freezes we will consider not to carry out the boat operation, but the car needs to meet the time in so can be used, for the car battery CCA is higher than the boat battery, convenient car in the cold conditions can be started quickly, change you may encounter this trouble.
No, using a car battery on a boat will bring huge potential problems, car batteries can’t cope with fluctuations on the water, although you can start the engine, the battery power will be drained quickly and can’t be supported for the next start, the battery will also have a large amount of electrolyte leakage during use to corrode the engine and so on.
Automotive batteries and marine batteries both use lead-acid batteries, is for two different ways of using different lead-acid battery design, different in the manufacturing process is essentially the same.
