The aim of the battery boost converter is to supply steady state power to the DC bus. Hence the converter is designed to deliver maximum load power. A 12 V, 7 ampere-hour lead-acid battery is considered for this application. The advantage of lead-acid battery is that the voltage drop during discharging is very low.
and battery failure. The relationship between maximum charging voltage and the number of cells in the battery is also significant. This will determine (for a given ambient temperature and state of charge) the rate at which energy is absorbed as heat within the battery. For lead-acid batteries, the voltage per cell must not ex-ceed 2.35 volts.

50% Depth of Discharge for Lead Acid Battery
For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less. To get an accurate reading of a battery''s state of charge, you need to use a battery tester or multimeter that takes into account the battery''s type and voltage ...
See my stack exchange answer to "Lead Acid Battery Charger Design Factors" which relates, and follow the link there to the Battery University site which will tell you far more than you knew there was to know about lead acid (and other) batteries.. From the above answer note the quotes from the above website. Especially in this context. The correct …

BU-303: Confusion with Voltages
To use a multimeter for measuring battery voltage, you need to set it to the DC voltage setting. ... The recommended charging voltage for a 12V lead-acid battery is between 13.8-14.5 volts. However, it is important to note that overcharging a …
17 Sizing. – Lead Acid usually operates between 1.75vpc and 2.33vpc depending on construction – NiCad batteries typically operate between 1.00vpc and up to 1.65vpc …
The lead-acid battery is the most commonly used type of storage battery and is well-known for its application in automobiles. The battery is made up of several cells, each of which consists of lead plates immersed in an …
System Voltage. System voltage is also called nominal operating voltage and refers to the DC operating voltage (battery bank voltage) of the solar power system. Generally, the system voltage is 12V, 24V or 48V. The system voltage value can be 110V and 220V for medium or large charge controllers. Maximum Charging Current
The ideal voltage for a fully charged deep cycle battery varies depending on the type of battery. For a 12V lead-acid deep cycle battery, the ideal voltage is between 12.6V and 12.8V. For other types of deep cycle batteries, such as lithium-ion or nickel-cadmium, the ideal voltage may be different.
These batteries apparently used for low voltage dc system like bridge navigational instruments, emergency lighting, GMDSS, etc. and thus kept charged to be used in case of emergency or need for temporary power. ... For example, the approximate value of a fully charged lead-acid battery is 1.280 at 15 degree Celsius. Voltage. Apart …
