Most vehicle alternators will never properly and fully charge up a Deep Cycle battery so invest in a good charger or a solar arrangement with a charge controller/regulator with at least a three stage charging control (many chargers are now 6 or 7 stage affairs).
How fast does an alternator charge a deep cycle battery?
Car batteries range from 40AH to 110AH, and alternators range from 45 amps to 200 amps. If you are using a battery charger, a 10 amp charger will take 4 to 11 hours to fully charge the battery, a 2 amp charger will take 2-4 days. Of course you don’t have to get the battery to full charge to get it to start the car.
How long does it take an alternator to charge a marine battery?
around 4-6 hours
In most cases, a marine battery will take around 4-6 hours to charge. This will bring your battery from 0% charged to 80% charged. In addition, it depends on the type of charger that you’re using. Some chargers are more efficient than others, which means that it’s important to pick out a high-quality charger.
Can you run a deep cycle battery in a car?
Deep cycle batteries were not made to power most vehicles. However, they are often used for recreational vehicles, boats, and golf carts. Because they deliver a steady flow of power over a long period of time, these batteries are also useful in solar panels and other plug-in electronics.
What is the best way to charge a deep cycle battery?
Trickle charging is the correct way to charge a deep-cycle battery.
Can any battery charger charge a deep cycle battery?
Using a traditional battery charger to recharge your deep cycle battery will not give you the best possible results.A deep cycle battery is not designed to handle the rapid charging and extra heat, so it may never reach full capacity.
How do you tell if a deep cycle battery is fully charged?
Voltage on a fully charged battery will read 2.12 to 2.15 volts per cell, or 12.7 volts for a 12 volt battery. At 50% the reading will be 2.03 VPC (Volts Per Cell), and at 0% will be 1.75 VPC or less. Specific gravity will be about 1.265 for a fully charged cell, and 1.13 or less for a totally discharged cell.
Can you jump start a deep cycle battery?
Many deep cycle batteries (that are about the same size as a car battery) can supply 6 amps for 8 hours, so this is about 1/2 the power (and 1/2 the weight). 11 of 12 found this helpful. Do you? Yes it will jump start a deep cycle battery just as easily as any other 12 volt battery.
How long will a deep cycle battery hold a charge?
The standard and most widely accepted rating period for deep cycle batteries is 20 hours. This means that the battery was discharged down to 10.5 volts over 20 hours while measuring the total amp hours it supplies.
Do you need to charge a new deep cycle battery?
New batteries should be given a full charge before use. New deep cycle batteries need to be cycled several times before reaching full capacity (50 – 125 cycles, depending on type). Capacity will be limited during this period. Battery cables should be intact, and the connectors kept tight at all times.
What is the difference between a starting battery and a deep-cycle?
Overview of Cranking Battery vs. Deep Cycle Marine Battery: A cranking battery ensures a boat can easily start and get out on the water. A deep-cycle (trolling) battery keeps it operating and runs electronics in any conditions.
Can a standard deep cycle battery be used as a starting battery in a 4wd?
Deep-cycle batteries tolerate starting duties far better than starter batteries tolerate deep-cycling. But, size-for-size, you can’t match a starter battery’s ability to provide quick hits of power to crank a starter motor.
Do I need a deep cycle battery for my car?
A deep cycle battery can provide a surge when needed, but nothing like the surge a car battery can. A deep cycle battery is also designed to be deeply discharged over and over again (something that would ruin a car battery very quickly). To accomplish this, a deep cycle battery uses thicker plates.
Can you revive a deep cycle battery?
A deep cycle battery can be reconditioned using distilled water, baking soda and Epsom salts at home. Start by draining the battery acid. Then, heat some distilled water and add the Epsom salt to it. Fill the battery cells with this solution.
Why won’t my deep cycle battery take a charge?
This is typically a symptom of battery age, damage from over/under charging, or sulfation. You can sometimes improve a battery in this condition by using a desulfation device, otherwise you’ll have to live with the low capacity or replace the battery.
Can you charge a deep cycle battery at 40 amps?
Charging a car battery at 40 amps shouldn’t be done for longer than 2 hours. Fast charging car batteries can be dangerous and should be done in short bursts. Failure to do so could result in explosions.
How long does it take to trickle charge a deep cycle battery?
Marine Batteries
It is not recommended to charge deep cycle batteries with only 2 amps. A deep cycle battery with an AH of 55 and 6 amps could take 10 hours to charge, while a similar battery with 105 AH and 30 amps will take about 4 hours to charge.
What is the minimum voltage for a deep cycle battery?
The lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use. Experienced RVers try to use no more than 20% to 50% of the energy available in a battery before recharging. That means they never let resting voltage get below 12.5.
What voltage should you charge a deep cycle battery?
Charging – Flooded Types
Deep Cycle Batteries in a cycling application require a recharging voltage of 2.43 to 2.45 volts per cell. This is 14.6/14.7 volts for a 12 volt nominal installation and 29.2/29.4 volts in a 24 volt site.
How far can you drain a deep cycle battery?
BATTERY TIP 4 – Never fully discharge a deep cycle lead acid battery! The deeper you discharge the battery the more it will reduce the battery’s total cycle life. We recommend discharging a battery to no lower than 50% DOD, with a maximum of 80%.
Can you charge a marine battery with a car?
Just connect the marine battery in parallel with the car battery, which is left in situ with no disconnection made, after making sure it is itself fully charged. The idling engine will charge the marine battery through its alternator.
