Re: Can I use a car battery charger on a marine battery? Yes a car charger will work. But you may need to pay attention, turn it off when the battery is full etc.
How do you charge a marine battery with a battery charger?
Set your battery charger to a slow or trickle charge and select whether you are charging a 6, 12 or 24 volt deep cycle battery. If your battery charger has the option to set the voltage for the charge, set it to 20 percent of the rated amp per hour rate of the battery you are charging.
Can I charge a deep cycle battery with a regular charger?
Using a traditional battery charger to recharge your deep cycle battery will not give you the best possible results. This is because excess heat is produced whenever a battery is charging. A deep cycle battery is not designed to handle the rapid charging and extra heat, so it may never reach full capacity.
What amp should I charge my marine battery?
The “Ideal Charge Curve”
Charge at a rate up to 20 percent to 40 percent of the batteries capacity in amp hours to a voltage of about 14.6 volts (gel: 14.1 volts). For example, a 200 amp-hour battery would be charged at 40–80 amperes.
Do you need a special charger for marine battery?
Most marine batteries are designed with two amps as their maximum value. Your charger should have a corresponding value that’s below this number. You don’t want two amps as your charging power because that amount equates to a fast charge. Trickle chargers have a much lower, amperage value.
How long does a marine battery take to charge?
A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value. Chargers with only 5 amps, however, will need a full six hours with the same battery.
Is it better to charge a battery at 2 amps or 10 amps?
It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
How often should you charge a deep cycle marine battery?
They should be recharged when they indicate a 50% charge, but never let them get lower than 20% to ensure a long life. Lead-acid batteries, such as deep cycle batteries, run the risk of sulfation if left uncharged for too long.
Can you overcharge a deep cycle battery?
Overcharging Deep Cycle Batteries:
As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.
What is the best way to charge a deep cycle marine battery?
There are two main approaches to charging up a deep cycle battery. The first is to charge the battery while it’s on the boat already, in the fixed position. The second is to take the battery out of the boat and make use of a portable charging unit to top the battery up to full.
Should I leave my boat battery charger on all the time?
Will I damage my batteries if I leave the charger plugged in over long periods of non-use (like storage)? No. … This will allow you to keep your battery charger plugged in for long periods of time without “boiling the battery dry.” Note: It is important to check the electrolyte level approximately every 30 days.
Does a boat battery charge while running?
Once the outboard is running, its alternator will recharge the cranking battery to compensate for the power delivered while starting the motor, and for any power drawn for other “house” needs, including live well or bilge pumps, fish finders, or navigation lights.28 мая 2019 г.
Is there a difference between deep cycle and marine battery?
A deep cycle marine battery, or trolling battery, has several design differences. One key is plates: It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods. Deep cycle batteries can be entirely drained and recharged many times over, cranking batteries can’t.
Can you overcharge a marine battery?
When you overcharge your battery, you cause the acid inside to boil or percolate, which can cause your battery to crack, ruining the battery completely.
