If more information is needed on the state of a 12-volt automotive battery, testers can be used which give much more information.
One such unit is the TT TOPDON ArtiBattery 101 which can do full test on 8-16VDC automotive batteries.
Test include the State of Health, Cranking / Load Test, Charging Test and more.
*This unit was sent to me to review with my honest opinion and results below.
It will ask a few questions such as language. It also will need the Amps the battery is rated for which should be on the side or top of the battery.
