If the vehicle is running you should see between 13.5 volts and 14.5 volts. If the engine is off, you should have at least 11.5 volts. Voltage alone is not enough to determine the "health" of a battery. If a battery may be the cause of a problem then have it load tested by your local parts store or automotive shop.
Should read 14 volts.
With a fully charged battery (12.68 volts) and engine running at idle with no accessories on, 14.5 volts. You will not get a accurate reading if the battery is not fully charged.
12 volts!!! 12 volts!!! Real Answer 13.1 volts (Depending on Battery)
With the engine not running you should read 12.6 volts on a fully charged battery. With the engine running you should read from 13.5 to 15.5 volts at the battery posts.
What voltage battery are you referring to? An automobile battery is 12 volts and a fully charged auto battery should read 12.6 volts.
Battery voltage which is 12.6 to 13.2.
13.9 to 14.2 volts.
depends on the kind of battery. a regular battery (aa,aaa,d,c) should supply 1.5 volts. a car battery should supply 12 volts
With the engine running you should have a reading of 13.5 to 15.5 volts at the battery. So 14 volts is acceptable.
You need to check the charging system with a volt meter. It should have 13.9 to 14.2 volts at the battery with engine running.
Should read from 13.5 to 15.5 volts.
Two possibles. Either the battery needs to be replaced, or the stator is not charging. First check the battery with the engine off, should have 12. 2 volts or more, if under 12 volts, then charge and check again. If under 12 volts, then replace. If over 12 volts, run engine, check the battery volts, should have over 13 volts at idle, rev up, should get over 14 volts. If battery still shows only 12. 2 or so volts, then the stator in the engine has to be replaced.
