Marine batteries are batteries for boats traveling on the water with electricity, in order to cope with the humid and changing environment on the water specially designed batteries for the engine machine, lights and other electrical appliances belong to the operation of deep cycle batteries, longer life than ordinary batteries of better quality.
(1) Starting batteries, starting batteries used to start the engine, the only advantage of starting batteries is that they can produce instantaneous high current to meet the starting current of the motor, and not good at storing power, starting batteries for deep cycle discharge will seriously damage the battery.
(2) Deep cycle batteries, deep cycle batteries are mainly used for power supply of electrical appliances on board, based on the strong storage and release ability of deep cycle batteries, they can provide stable and long term current, and their capacity is also larger.
(3) Dual-purpose batteries, dual-purpose batteries can support all electrical facilities, including engines, with a dedicated battery different dual-purpose batteries as a starting and storage batteries are not as good as them, dual-purpose batteries will be the two roles in one, the main convenience , do not need to replace the battery frequently.
(1) liquid-rich lead-acid batteries, cheap, short life of 2 to 3 years, simple battery structure, storage and release of power is weak commonly used in automobiles and boat starting batteries, unlike the traditional liquid-rich lead-acid batteries, as a boat his function is more powerful can also be for electrical appliances to provide power.
(2) AGM, also known as absorbed glass mat battery, belongs to lead-acid batteries, different from lead-acid batteries is AGM, although the same material with lead-acid batteries, but the AGM protection measures are better, will not occur in the case of leakage, the electrolyte is attached to the lead plate, the actual does not require too much maintenance, the price is also more expensive than the liquid-rich lead-acid batteries.
(3) Gel batteries, gel batteries, the performance of the battery is less prominent in the battery, mainly the use of gel agent will be converted to gel electrolyte, in order to cope with the surface of the water on the indefinite bumps, to maintain the stability of the battery, gel batteries on the charging is more sensitive to the need to be equipped with a special charger to ensure that the charging current is stable.
(4) lithium batteries, lithium batteries are powerful mainly for the ship’s electrical appliances to provide power is the best modern storage capacity of the battery can be completed to a greater extent of the deep cycle batteries, longer life for more than 10 years, but the price is also the most expensive of all the batteries to reach 130 U.S. dollars / kwh, its weight, discharge stability, capacity, etc., all have advantages.
Marine battery design is generally higher than the ground with the same kind of battery life, but in practice the life of the marine battery is much lower than the car battery, is because the boat has a mooring period car batteries can be used every day to think of the boat battery does not have to be replaced frequently on the need to pay attention to maintenance.
(1) connect trickle power, in the mooring period can try to connect the boat battery in the trickle power, trickle power current is stable and inefficient, can ensure that the boat battery power is always maintained in a healthy stage, to prevent excessive discharge of the battery.
(2) Avoid exposing the batteries to high temperatures, battery heating is the main factor that reduces battery power, people in some countries deliberately park their boats in cooler areas to cope with longer mooring periods to ensure that the boat as a whole is mainly a battery performer.
You should charge your batteries once every 30 days, many people do not have the idea of regular charging of marine batteries always put the boat aside for a few months without charging to re-use not only can not charge the battery even charged batteries can not be used can only be replaced by a new one, for so even if you do not artificially charge the battery, you can also install a small solar panels can ensure the safety of the marine batteries.
The marine battery waterproof, shock resistance, durability, are higher than ordinary batteries, marine batteries are the most important is the mooring period of the battery maintenance, for different types of boats battery selection start and deep cycle or dual-use or different differences.
