When the boat is traveling on the ocean, probably our biggest concern is whether or not the boat battery has enough power. This is especially important when the boat is traveling far from shore, as we may be faced with not being able to get back.
1. When you start the boat, you find that the engine rotates slowly or doesn’t rotate: Generally, the life span of a boat battery is 3~4 years, and you may need to replace the battery when it approaches or exceeds this time. So, if your boat battery is still in the 3~4 years period, the boat can be started easily. However, as the battery power decreases, the engine may take longer to start. If it takes more than ten seconds, the boat battery is exhausted or the battery is damaged. At this time, it is best to replace the battery, otherwise do not easily sail the boat.
2. Other electronic equipment failure: there are often other devices on the ship that need marine batteries to supply electricity. We can observe the other electronic equipment master running normally or whether the efficiency is low to determine whether the home battery has power.
3. Obvious damage: sometimes the battery failure, only from the appearance of the battery can be judged. Battery if there are bulging and rupture and other symptoms, it shows that the battery has some kind of failure, need to replace the battery in time.
1. Battery sulfation corrosion: in the marine environment, the salt content is particularly high, will accelerate the corrosion process of marine batteries. When the battery terminals are corroded, it will weaken the connection and reduce the electrical power output of the battery. The effect of weather and
2. Temperature: In cold weather, the chemical reaction inside the battery will slow down and the marine battery may not be able to provide you with sufficient power.
In hot weather, the reaction inside the battery is too fast and there are dangers such as overcharging.
3. Boat batteries are different: Batteries of different qualities and shapes can withstand different kinds of trouble.
For Absorbed Glass Mat batteries (AGM), lithium batteries, and classic lead-acid batteries are made of first-class materials, a process that protects them from problems such as sulfation and thus extends their service life.
4. Low Battery Voltage: Undercharged or aging batteries can lead to low battery voltage.
1. Do not start the battery immediately, most boats are equipped with deep cycle batteries (to handle deep discharge states) and they cannot be recharged after jumpering.
2. Check the battery voltage, use a battery tester or voltmeter to check the voltage of the marine battery. Marine batteries should be at least 12.8V when fully charged, but due to on-board computers and other technology, the full voltage is slightly lower and should be no less than 12.4V. If the voltage tester shows less than 12.4V, it is important to be aware of this and to be prepared to replace the batteries at any time.
3. Replacement of spare batteries, go out, often carry spare batteries in time to replace the spare batteries to ensure stable voltage and sufficient power.
1.Remove corrosion frequently. you can resist corrosion by maintaining your boat battery regularly, using baking soda and water mixed together to clean the battery terminals will weaken the corrosion. Don’t be lazy and leave it untreated; over time, your marine battery may stop working.
2. Keep it fully charged: Charging the battery frequently can prolong the life of the battery. You can use a hydrometer or battery tester to measure the power level.
3. With temperature regulation: Avoid boating in extremely hot or cold weather conditions, not only do you not have a good boating experience, but it is also a damage to the boat battery.
In order to prevent the battery from draining and damaging quickly, purchasing a high-quality marine battery (such as lithium battery) is undoubtedly the best solution. Although it is a bit expensive, it does have a long service life and is still friendly for partners who don’t want to change batteries frequently.
