50% discharge on AGM batteries
For a 225 Ah battery, your lifetime capacity is 71,000 Ah if discharged to 50%, but is 72,000 Ah if discharged to 80%. Indeed, If you look at Odyssey''s data for 100% DoD, you still get 72,000Ah of lifetime capacity! For Odyssey batteries, there is absolutely no reason to worry about your DoD, you''re not gaining anything by starting up that ...
Lead-acid battery
OverviewHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplicationsCycles
The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for us…
Understanding Solar Battery Depth of Discharge (DoD)
If fully discharged, batteries, especially certain chemistries like lead-acid, can suffer from sulfation and irreversible capacity loss. Avoiding fully discharging batteries to maintain their longevity and overall performance is highly recommended. ... An 80% DoD battery means it has been discharged to use 80% of its total capacity. This ...
Lead acid batteries (Calculation) :: PV*SOL® help
The discharge cut-off voltage given by the maximum discharge depth must also be observed. To protect the batteries, they must not be discharged by more than 80% as a rule. Since the total capacity of the battery changes with the discharge current, the final discharge voltage also depends on the current, as shown in Figure 1.
How Low Can You Discharge an AGM Battery?
How Far Can You Discharge a Lead Acid Battery? Most lead acid batteries can be discharged down to 40% of their capacity. However, this varies depending on the type of battery. For example, deep cycle batteries can usually be discharged to 50% without damaging them, while starter batteries should not be discharged below 70%.
BU-403: Charging Lead Acid

BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. ... In delivering 60AH into a test load, the drop in SG showed about an 80% discharge. I compared the size and weight of this battery with those of a 90AH battery advertised online and these numbers were in good agreement. For measuring discharge …
AGM vs Lead Acid Batteries: 12 Differences + 9 FAQs
The flooded lead acid battery (FLA battery) uses lead plates submerged in liquid electrolyte. ... AGM batteries have an 80% depth of discharge (DoD), which is better than the 50% DoD offered by a flooded cell battery. This makes the AGM battery well-suited to deep cycle applications.
Lead-Acid Batteries
Do lead-acid batteries discharge when not in use? All batteries, regardless of their chemistry, will self-discharge. The rate of self-discharge for lead-acid batteries depends on the storage or operating temperature. At a temperature of 80 degrees Fahrenheit a lead-acid battery will self-discharge at a rate of approximately 4% a week.
Battery Runtime Calculator | How Long Can a Battery Last
This calculation considers: Battery Capacity (Ah): The total charge the battery can hold. State of Charge (SoC): The current charge level of the battery as a percentage. Depth of Discharge (DoD): The percentage of the battery that has been or can be discharged relative to its total capacity. Total Output Load (W): The total power …
