The voltage of a lead-acid battery at 50% discharge depends on the specific type of battery and its design, but generally:
However, keep in mind that this is an approximation, and the voltage can vary slightly depending on factors like battery age, temperature, and load conditions.
Also, lead-acid batteries should not be discharged too much (below about 11.8V) as it can damage the battery and reduce its lifespan.
- A fully charged 12V lead-acid battery has a voltage of around 12.6–12.8V.
- At 50% discharge, the voltage typically drops to about 12.0V.
