There are many factors that will affect the battery backup time like battery DOD limit, Output AC/DC load, inverter efficiency & battery discharge rate which I have explained in detail. Thats because an 800 W air conditioner on 240V requires fewer amps than an air conditioner on 120V. A 12V 7Ah battery, for example, will last 7Ah/10A = 0.7 h = 42 minutes when providing 10A. To calculate the hours run duration, we can simply utilize the current drawn by the load and the Ah capacity: Battery runtime equals Ah capacity divided by load in amps. 3A(3000mAh)*3.7V=11.1W Every size battery has its amps discharge rate (Depending on the brand) 18Ah batteries mostly have a discharge rate of 20 hours which means they are recommended to be discharged at 0.9 amps per hour. The equivalent of 10000 mah is around 3.7 watt-hours or 3.7 amp-hours. Similarly, How do I calculate how long a battery will last? #4 johnnyha 3. A 100Ah 12 volt deep-cycle lead-acid battery can run a 400W continuous DC load for 1.5 hours with the recommended 50% Depth of Discharge. For most users, an 80 percent battery health level should be sufficient to carry them through the day.

Correct these calculations with the efficiency of the boost converter and add in some safety factor for deterioration of battery over time. Yes, you can upgrade from the 12V 18Ah to the 12V 20Ah to enjoy a longer run time. 100W/10A=10V a 12V 20ah battery is designed to have a 1amper to 2 ampere drain for 10 to 20 hrs. Knowing this information can help you avoid being stuck without power when your car is most needed. PS: quick notes: if space allows, cylindrical battery cells will always be your first consideration on the table. if size are given or can be checked by a ruler, we can then get the battery capacity.The size of Lithium polymer battery has a great impact on its capacity, thats the thickness, width, and length of a battery. Energy Density of Different Battery Types, Lets say what would be the battery capacity at 11.1V 7kgs. Battery Size: I have this (app) application and I need it to run for (X) hours, what size battery will I need? Secondly, How long will a deep cycle battery last calculator? So to converter Ah into watts (watts = Ah x volts), 12V 12Ah battery means 144 watts of capacity which you can use to run your small devices like LED bulbs, charging phones, etc, These small batteries are designed in a way to so they can draw a small amount of power slowly for a longer period of time or in simple words 12ah battery will last 1 hour if youre running a 1A capacity device with it. I have two sealed lead-acid batteries in parallel that have that inscription on the sides. Also, How long will a car battery run a 3000 watt inverter? The Mighty Max Battery 12V 18AH is a replacement battery for the Diehard . Why is operating on Float64 faster than Float16? It may be used to calculate the run duration of devices that demand a certain amount of watts or amps. A 100Ah 12 volt deep-cycle lead-acid battery can run a 400W rated AC fridge for 15 hours at a rate of 40 watts per hour. heres a list of appliances connected with a 12ah battery and how long your battery will last while running those appliancesApplianceWatts requiredEstimated Running time with 12v 12ah battery22 Inch LED TV17W8.4 hours32 Inch LED TV20W7.2 hours42 Inch LED TV58W2.4 hours55 Inch LED TV116W1.2 hoursAir Purifier25W5.7 hoursAquarium Pump20W7.2 hoursCeiling Fan60W2.4 hoursDVD Player30W4.8 hoursElectric Shaver15W9.6 hoursLED Light Bulb10W14 hoursPhone Charger7W20 hoursTablet Computer10W14 hoursWall Fan60W2.4 hoursWiFi Router10W14 hoursHow long will a 12ah battery last?Sponsored Linksvar cid='4723393190';var pid='ca-pub-2366332532233784';var slotId='div-gpt-ad-portablementor_com-medrectangle-3-0';var ffid=1;var alS=1021%1000;var container=document.getElementById(slotId);container.style.width='100%';var ins=document.createElement('ins');ins.id=slotId+'-asloaded';ins.className='adsbygoogle ezasloaded';ins.dataset.adClient=pid;ins.dataset.adChannel=cid;if(ffid==2){ins.dataset.fullWidthResponsive='true';} To learn more, see our tips on writing great answers. Custom Medical Battery Pack This in turn reducing the current by 1/10 to achieve the same W/hr rate. If I have a 12v battery with 170ah, will the pump run continuously for 26 hours? I have continuous load of 800 watt. As a battery becomes older, its ability to hold a full charge decreases. Actully the formula works for all volts including, Lets say a 12V 100Ah solar lithium battery to be used for a 12V 30A device, 1 when you convert the battery with the same volt and same Ah or mAh, you can use the fomula and just ingore the volt. Medium answer: If your battery is an 80 Ah battery (that is a smallish car battery) it will be 80% drained after 12.8 hours (after 15.2 hours the battery is 90% used up).
