Understanding Car Battery Voltage and State of Charge

A typical car battery is a lead-acid battery consisting of six cells, each producing around 2.1 volts when fully charged. When the engine is off, a fully charged car battery should have a total voltage of around 12.6 to 12.8 volts. When the engine is running, the alternator increases the battery''s voltage to between 13.7 and 14.7 volts to keep it charged.

New 9V alkaline battery at 9.6V? Used to be ~9.3V

I''ve been buying them for the better part of 10 years and for all that time, every single one had a new voltage of 9.20-9.35V (in circuit, light load ~20mA). The last pack I got had a different shape and the voltage on each one was around 9.6V. Is there a new alkaline technology around? Duracells.png (896.83 kB, 800x700 - viewed 237 times.)

Is a battery healthy if drops under 10 volts with load?

A good battery will sit around 12.6 to 12.8 volts when fully charged. When a good battery is put through a load test equal to its rated CCA (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts depending on the ambient temperature. It will then shoot back up to ~12.6 volts once the load is removed. Bad Battery
