There are many ways of charging a battery, plus a myriad of chargers to choose from. Yet one of the most common questions is that, what charger should one use when charging a car battery, 2 amp or 10 amp?. This is mostly a question that focuses on charge time, because determining how long to charge a battery is important so that you can schedule tasks in line with when the task finishes. If you know how many amp hours your battery has, you can calculate how long the battery takes to charge. To figure that you can use a simple formula. Time= Amp-hour/Battery Amps. For these examples, we are using a 48 amp battery. Using 2 amps. Using a 2 amp charger on a 48 amp battery takes 24 hours to charge from empty.
An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on. A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery.
How long to charge car battery at 10 amps. A charger designed for a 12 volt battery should not be used to charge an 8.4V battery. It is likely to damage the battery and in the worst case can cause a fire. How long to Charge a Car Battery at 10 Amps. A 10 amp charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 2 to 3 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 3 to 4 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 4 to 7 hours. Double these times if the battery is fully discharged. Basically the higher amps will allow you to charge a battery in a shorter period of time. When a battery charger says it is charging at 2 amps or 10 amps it is describing the number of amps it is delivering to the battery per hour. So when you are charging a battery at 2 amps then it takes 24 hours for the battery to receive 48 amps of charge.
How Long to Charge a Car Battery at 10 Amps (260-14) When you are using a 10 amp battery charger, it will generally take 4-5 hours to charge a 48 amps car battery. Now, you may have a question: charging a car battery, 2 amp or 10 amp (50-18) or charging a deep cycle battery 2 amp or 10 amp (320-35), which one is better? Charging an ATV battery at 10 amps would overheat it and damage it permanently. Can you charge an ATV battery with a car battery? You can use jumper cables to jump-start an ATV battery from a car battery, but it is not a suitable method for doing a full charge. The car must stay off as long during the whole process. The most common rate for car battery chargers is around four amps. To fully charge a battery of the size 52Ah would take about 10 hours from dead to fully loaded, but you would probably be able to start your car within 1 hour. First, you have to take a look at your car battery charger to find out how much ampere it’s giving out.
A car battery generally holds 48 amps, so it will take about 12 hours to reach a full charge using this voltage. This could be a good choice for charging your car battery to maintain a certain level for a long period of time. Length Of Time Using 10 amps . A 10-amp charger is able to charge a half-discharged small car battery in about 2-3 hours. The easiest way to determine the appropriate battery charger is to use 7 – 10% of the rated amp-hour capacity of your battery. For example, if you had a 50 amp-hour rated battery, you would to select a battery charger with a peak amperage rating of 3.5-5.0 Amps. How Long To Charge A Car Battery At 6 Amps 1 In my own experience, the battery charged in a long time is quite safer as compared to the battery charged in less time because to hasten the process we usually take a high powered charger which can harm your battery. So it is better to use the charger of fewer Amps as it will safely charge your battery.
Thanks to the unidentified phantom battery drain hidden somewhere in the deep recesses of my B250 camper van, my brand-new Costco Kirkland Signature battery went dead. I pulled it out of the van and put it on a 10-amp charger. It’s been charging for about 5 hours now, and the ammeter has dropped from the initial 10 amps or so down to the 1-2 amp range, though it’s hard to get an exact. Now, if this is your first time having a dead battery, the best solution is to charge it slowly, with 12 volts and 2 amps for several hours. When you buy the charger, you can see this setting, and it’s usually labeled green. Get your amp hours off your battery, and the charger amps off the charger. (Again, the charger amps may vary, but just go with the maximum rate you’ll be using.) Next, determine your depth of discharge. You’ll need a voltmeter or car battery tester, and our article for guidance on how to test a car battery for this, by the way. A fully.
If you want to charge your battery within a short time, you will need a high amp charger, which takes a shorter time. The most preferred for most car batteries is between 10-20 amps. Lower amp chargers will take long, but charging is safe. For example, using a 2 amp charger will take about 6 hours to charge a 12-volt car battery. How long to Charge a car Battery at 2 amps. Charging your car battery with a 2 amp car battery charger will take a reasonably long time, up to 24 hours to reach an acceptable charge, this is determined by the fact that your car battery is usually 48 amps and it takes about 1 amp charge per hour on average. How Long to Charge a Battery: Evaluating the Main Details. There are many possible issues that could lead to your car battery taking longer to charge. Typically, a car battery charger that charges at about 2 amps will require about 24 hours to deliver the full 48 amps your battery needs for a full charge.
A basic car battery charger usually charges at 2 amperes. On average, car batteries hold 48 ampere-hours, so it typically takes a full day to charge a car battery. However, there are other car battery charging solutions that offer up to 10 amperes. I'm charging the battery in my car. My battery charger has a 6 volt setting which I do not use. It also has a 12 volt / 2 amp charge setting and a 12 volt / 10 amp charge setting. Which one of those should I be using? My battery is not dead, just seems weak. I'm going to see if charging it works before I go buy a new one. How long to charge a car battery at 2 amps? A charger with only 2 amps will take a long time to get your battery back up to full capacity, but it is a safer and more controlled way of recharging. Your risk of overcharging your car battery is far lower. You also don’t risk heating up your battery too much during the process.
Step 3: Charge your car battery with a 10 amp charger in order to add that accurate amount of amp hours into the battery. To determine the charging duration, you simply have to divide the amp-hours of the battery by 10 (with a 10 amp charger). Charging Duration= amp-hours left in the battery / 10 amps of the charger 2. How Long To Charge A Car Battery At 4 amps? Normally, a deep cycle battery often holds 48 amps so if you charge it at 1 amp, it will take you 48 hours. Similarly, if you charge your car battery at 4 amps, the total time to make the battery fully charged is about 12 hours. The amp hours allow you to measure car battery amps through the practical lens of how long it will last between charges. If a battery’s ampere-hour is 100Ah, this tells you the battery can deliver 5 amps of power for 20 hours.
OK all that being said normally about an hour at 10 amps will do it, on an average battery in good condition. Now there are ways to check to see if the battery is charged. One is with a battery hydrometer, that is if you have the type the cells open up on. Battery hydrometers are very inexpensive.
