let's assume that you have a 12v 100Ah lithium battery connected with a 500W inverter running at it's full capacity and the inverter is 85% efficient So a 100Ah lithium battery will last 2 hours on a 500W inverter Load Connected with inverter?
The runtime of a 12v battery with an inverter depends on battery capacity, device power consumption, inverter efficiency, battery health, discharge depth, and environmental conditions.
Here's the magic: by connecting your 12v battery to an inverter, you unlock the potential to power various devices, bringing a touch of home comfort to your off-grid adventures. But there's a catch – the amount of time your battery can provide power depends on several factors. That's what we'll explore in the next part!
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). I won't go in-depth about the discharging mechanism of a lead-acid battery. Instead, I'm going to share the key points to remember when discharging your lead-acid battery.
50% Depth of Discharge for Lead Acid Battery “Lead acid batteries should be discharged only by 50% to increase its life” – is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter.
The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer's specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C
“Lead acid batteries should be discharged only by 50% to increase its life” – is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid battery is only 50% of the rated capacity.
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let's suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid battery is only 50% of the rated capacity. So if you have a 100Ah battery, you can only use 50Ah. In this blog, I will provide reasons as to why this is so.
Therefore, 50% represents a good balance between capacity and cycle life, also taking into consideration the cost of replacement. So why should we not discharge more than 50% for lead acids? This is because if the DoD is more than 50%, it would reduce the life of the battery. How & Why?
