More importantly, it lets you run your appliances off of stand… While you are bondocking, apart from generator you also need to use batteries to power some of the appliances. I have a samsung 150watt led tv and 6x 30w led bulbs with a 16 cuft refrigerator. Solar panels have also become popular with increasing efficiency and the cost not so very high. So, while bondocking how much battery do you really need then? The fridge consumes 9 watts per hour and it will run for 24 hours each day. These can vary from powering a blender or TV for an afternoon of tailgating or keeping food refrigerated during a month-long camping odyssey. Equipped with premium cranking power and impressive cycling capability, they are perfect Why Pairing An ArkPak With Your ARB Fridge/Freezer Is A Good Idea Average run cycle is 10 hours. I am going to build a portable battery pack from Leaf modules soon. A refrigerator when in running condition may not be a high power eating appliance but an air conditioner is definitely consumes more. Most common dometic or narcold refrigerators made specially for RV can last for around 6 to 8 hours on 12 V DC battery depending on the size of the refrigerator. You should not use more than 5Amp load on a 100AH battery if you want it to last as Deep Cycle batteries don’t like being overloaded for long periods. A starter battery is designed to use a lot of power for a short period of time (starting a car). Residential refrigerators too have made into RV’s and are becoming good for RV usage. 4.5/5 (2,971 Views. OPTIMA® batteries have very low internal resistance, which can allow them to operate well beyond their specified ratings. It would be wise to only run it for 5-hourly cycles of 20-minutes each to still have a prayer at starting your car. Batteries are a form of DC or direct current. Batteries are a form of DC or direct current. Whereas a deep cycle battery is designed to deliver low amounts of power continuously for a longer period. This consumer managed to find out that his refrigerator consumes anywhere from 290mA (.29 Amp-hours) to 610mA (.69 Amp-hours), depending on the outside air temperature and other similar factors. It isn’t good to run a battery all the way down to zero during each charge cycle. When using a deep cycle battery across multiple days, it is important to consider the amount of power you'll need to put back into the battery to ensure continued operation. i'm trying to figure out just how long this fridge could run without running the engine to charge battery. An inverter is an electrical device that converts 12-volt power into 120-volt power. Using the inverter calculator, indicates ~14.35 Amps DC load and then running the sizing calculator suggests that I need battery capacity of 306 AH 20 hrs. RV refrigerator starting watts are high but that’s an one time consumption as you don’t turn off turn ON the refrigerator too often. This would include all of our YELLOWTOP® and BLUETOP® (except the 34M BLUETOP) batteries, but none of our REDTOP® batteries, which are considered SLI (starting/lighting/ignition) batteries. You would at-least need 700 amp hours to run for a day. If you are boondocking, one can also use solar panels to charge the battery during day times. However, in reality, if you discharge a lead-acid battery (what you likely have in your RV) more than 50% of the rated capacity you will greatly shorten the life span of the battery. Size of Generator To Run A Chest Freezer or Refrigerator. A typical deep-cycle RV battery will be rated around 80 amp-hours, which in theory would supply one amp for 80 hours. Looking for suggestions? If you compare this with other appliances then air conditioner is other appliances that consumes similar or more watts. It can be confusing. The advantage of using a good quality deep cycle Lithium Battery is your depth of discharge can go down to 75%. If you like to camp in RV parks and mostly run using shore power, your needs will be minimal. So the battery will drain out quickly. Therefore, you should view these times as theoretical maximums and discount them a few hours to make sure you don't ruin your battery by over-discharging it. That means someone who only discharges their battery to 80% may see 100-200 more cycles than someone who discharges their battery to 60% (approximate numbers cited only as a rough example, that can vary significantly in a given application). A refrigerator too can be powered using a 12 V dc battery. This means that the fridge will consume 216-watt hours per day. So comparing a 100Ah deep cycle battery and a 35Ah starting battery doesn’t make any sense. Battery Cycle life considerations. for accessory loaded vehicles. A 100 ampere-hour deep-cycle battery with a power inverter can power a 32″ LED TV at 35 watts for 34 hours, or a smaller 20-watt TV for about 60 hours until the battery is fully discharged. In general, you risk damage if a rechargeable lead-acid battery is drained below 50 percent of capacity, so you safely can draw 105 amps for only 30 minutes. To check how much is the consumption, one activity you can do is to put off all the devices that run on battery and keep only fridge ON. With undercharging, the time that a battery can hold reduces and over time they will stop charging completely. So, what do you do while traveling. For example, we will run the refrigerator for an hour and then turn it off to run the well pump. Connecting batteries in series increases the voltage but not the amps. A very small user of power is a 1.2 watt LED light running on a 12 volt power source will use 1.2W / 12V = 0.1 amps. In general, you risk damage if a rechargeable lead-acid battery is drained below 50 percent of capacity, so you safely can draw 105 amps for only 30 minutes. Deep-Cycle vs Starter Batteries and Your Car Fridge Save fuel. that have fifteen times more vibration resistance making it the perfect choice for your boat. Need help with OPTIMA products? Lets assume my deep cycle battery has an RC rating of 140. RV refrigerator is an important appliances while camping in RV. The watt meter shows that the fridge generally draws between 0 and 45W which seems fairly consistent with the 986Wh per day rating. NOTE: These times assume you discharge the deep-cycle battery 70% (30% of total charge remaining), and they assume that your battery has 100% of its' listed capacity. You need to calculate the usage of all your appliances and then configure the batteries. With 2 way refrigerators being more common now, you are left with only propane as the source while traveling. A battery bank designed to power an average American household for three days would need to supply 90 kilowatt-hours of energy. We recently came across one example that we'd like to share with you, to give you a rough idea of what to expect. Normal deep cycle batteries have a cycle life of about 1500 times, when you only use 30% of their capacity. You can use multiple batteries and connect them in series or parallel combination to get the required 12 Volts and sufficient amps for all your appliances. Subscribe to our newsletters now and stay up to date with new collections, the latest trends and exclusive offers. That’s alternating current, not air conditioning. Hotter temperatures may make the fridge work harder and consume more energy, as would opening and closing the fridge repeatedly throughout the day. To make a battery compatible with an AC device, you need to convert one form of power to another, which is precisely what your inverter does. First, a quick lesson in electronics for those who don’t quite understand what an inverter does. How long will my fridge run from my vehicle’s starter battery? Also, putting your batteries for microwave or air conditioner may not be a practical way and thus avoid as far as possible. The 12 volt deep cycle RV battery is more common than 6 volt RV batteries. Features like climate control will add on the amps drain as well. If there are other accessories connected to the same battery, the runtime may decrease significantly, depending on the demand of those other accessories. While the batteries provide for power in condition that have no other sources, it is necessary that you take sufficient care of them. Keep the refrigerator doors closed most time and open only when needed. So, get your priorities right and put on the devices on DC power accordingly. Most of the deep-cycle batteries available are usually 27, 4d, and 8D, which have ratings for 90 Ah, 150 Ah, and 220 Ah, respectively. Amps drawn are basically the per hour wise and with a normal RV battery of around 100 amps you can easily count on the hours.
