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.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.
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
The lead-acid battery performance is comparatively stable but reduces with the passage of time. Temperature correction factor: The battery cells capacity is generally provided for a standardized temperature which is 25oC and if it varies somewhere with the installation temperature, a correction factor is needed to implement.
Table 1 summarizes the characteristics of lead acid systems. Well-suited for SLI. Low price; large temperature range Big seller, cost effective, fast charging, high power but does not transfer heat as well as gel. Performs well when cold. High ambient rating, high cycle count, less prone to sulfation, needs correct charge; costly.
Load (ampere or watt): Specify the load value, and select the load unit. For example, 100 Watt. Or 10 A. Use an average value if it is a cyclical load. Voltage (Vdc): Specify the battery voltage in volts DC, if the load type is watt. Required duration (hours): Specify the duration that the load must be supplied for.
