How to Test a Marine Battery – Make Them Last Longer
Did you had any idea that a car battery can be used on a Test a Marine Battery, yet the battery types used on boats are normally not car batteries? The battery load prerequisites of a boat are a lot of one of a kind to that of a car. Its electrical framework is, generally, a battery-run framework.
One of the last things you do before the start of the boating season is make certain your boat’s starting and profound cycle batteries are completely charged. They were completely charged at the finish of the past season, before you sent your boat into its colder time of year hibernation and the battery charger could overcharge them, however how did they hold up over the colder time of year?
Yeah, we hear you. Almost everyday, we get calls and remarks about batteries that “won’t hold a charge” any more. Maybe you’ve been in that Test a Marine Battery. To clear up a confusion: a battery isn’t similar to a water bottle. You can’t go through half presently, and then, at that point, wait and utilize half later. It’s anything but a tank of power. Also, batteries don’t “leak” power like water can. What we’re dealing with is a lead acid battery in a plastic box that encases a delicate balance of chemicals which are ready to interact with each other to deliver power when the load is applied.
How to test a battery:
Here are a ways to Test a Marine Battery at home, and decide whether it’s bad:
1) Inspect the Battery
Bad Battery Bent TerminalSometimes you can figure out whether your battery is bad by essentially taking a decent look. There are a couple of things to examine:
- Broken terminal
- Lump or knock in the case
- Crack or break of the plastic
- Over the top leaking
Loosened up or terminals are dangerous and can cause a short out. Assuming a short happened, there would be some indication of consuming or liquefying. At the point when a battery shortcircuits, all the power is unloaded in an instant. That creates a ton of heat, and now and again even causes the battery to detonate.
Assuming that the battery is as yet intact, yet there is a lump in the case, this is usually a consequence of being overcharged. Different signs, for example, physical openings in the case are frequently caused by mishandling. Cracks, parts, and openings won’t cause a battery to stop working, however for safety reasons the battery ought to be labeled unsafe to utilize.
With wet-cell (overwhelmed) batteries, water levels should be maintained. Assuming that they are low, usually topping off them with refined water will help. Be that as it Test a Marine Battery, assuming the cells inside the battery have been presented to air for quite a while, it can cause an issue. At the point when the plates inside each cell are presented to oxygen it can rapidly dry the paste that encompasses the lead plates.
2) Take a Voltage Reading
The voltage of a battery is a decent way to decide the state of charge. Here is a handy table with the breakdown:
- Reading 0 volts, chances are the battery encountered a short out
- Cannot reach higher than 10.5 volts while being charged, then the battery has a dead cell
- Completely charged (according to the battery charger) yet the voltage is 12.4 or less, the battery is sulfated
However, assuming a battery sat, uncharged, seriously discharged, and/or drained for expanded timeframes, the sulfation will increase in size and harden onto the plates. This covers the surface area of the plates, eliminating the chemicals expected to deliver power.
Sulfation decreases the potential to reach a full charge, and it self-discharges the battery faster than normal. Charging a sulfated battery is like attempting to wash your hands while wearing gloves. At this point, charging alone won’t restore the battery to a healthy condition. The majority of replacement battery purchases happen when the original battery has reached this point.
3) Load Test the Battery
Your local automotive shop is more than able to load Test a Marine Battery, yet it’s very easy to do at home and all you want is a digital voltmeter. For any load test to be accurate, the battery should be completely charged and left to sit 12 hours before load testing the battery. An as of late charged battery will hold a residual charge from the charger, so allowing the battery to sit for 12 hours will release that residual charge and give you a more accurate sense on how the battery will perform under normal circumstances. To the test…
We should involve a motorcycle battery for an example:
- Eliminate the seat and uncover the battery in your bicycle so you have access to the terminals. Try not to separate the battery because you will attempt to start the bicycle.
- Hold the prongs of your voltmeter to the right terminals on the battery.
- Presently press the start button and watch what the voltage drops to. It doesn’t matter in the event that the bicycle starts or not, what you’re searching for is a voltage reading.
- A healthy 12 volt battery ought to maintain a voltage range from 9.6 – 10.5 volts under the load for a decent 30 seconds straight.
For starting batteries we don’t anticipate that you should run the starter for 30 seconds, so assuming you see the voltage meter drop inside the voltage range and it seemed like a decent solid start, then, at that point, you probably had a discharged battery. However, on the off chance that under the starting load the voltage dips under 9.6v, it is in all probability time to replace the battery.
The hardware on the boat won’t work, the boat won’t start as expected, voltage dip under 12.4V even after recharge, fails in a Test a Marine Battery, and physical wear and tear are the symptoms of a bad boat battery.
How can I say whether my marine battery is bad?
Indications of a bad boat battery are either gadgets onboard won’t work, the boat won’t start, voltage shows beneath 12.4V after recharge, fails in a load test, physical wear and tear. A bad battery can in any case put 12.6V yet can’t hold it for quite a while under load, so a clear study is an unquestionable requirement while replacing one.
Can you load test a marine battery?
Batteries should be at 100 percent voltage before a load test can be applied. While load testing eliminate all battery cables from their terminals. Utilizing a load tester, apply a 15-second load equivalent to half of the battery’s CCA rating. Allude to the load testers least passing voltage to decide the battery condition.
How long will marine battery last?
Most marine batteries last anywhere from 2 to 5 years relying upon the degree of care you give them. Most batteries accompany a one year warranty, however more costly batteries could accompany as long as three years of warranty.
