IntroductionI like building battery-powered circuits, but always in the back of my mind is the thought that I really ought to provide a ''low-battery'' indication! Since it isn''t usually a core feature of the project, it often gets forgotten. This ultra-short blog post describes my attempt at a generi
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 characteristics.
