A fully charged 12 volt automobile battery will read 12.6 volts with the engine not running and 13.5 to 15.5 volts with the engine running. It will read 12.4 volts with a 75% charge, 12.2 volts with a 50% charge and 12.0 volts indicates a 25% charge.
625
It should output the same voltage that any 12volt battery system outputs. Roughly between 13 and 15 volts (13.3-14.9)
13.6 to 14.5 volts with all accessories turned on, depending on temperature.
yes it can and if you run the engine long enough after u jump start it you can recharge the battery Also, you might want to check to see if the alternator is alright because a bad one might be why your battery is dying unless you know it is a bad battery specifically.
As many as you want. But where do you find 640 volts RMS?
If the type of light bulb you are using was made to run on 1.5 volts, a 1.5 volt battery should be able to light up one or several of those types if they are each wired in parallel directly across the 1.5 volt battery.If the type of light bulb you are using was made to run on 0.75 volts, a 1.5 volt battery will light up two or more of those types if they are wired in pairs in series across the battery.If the type of light bulb you are using was made to run on, say, 3.0 volts, a 1.5 volt battery will not light it up very much - it may just glow dimly.If the type of light bulb you are using was made to run on any voltage higher than, let's say 5 volts - for instance a standard 120 volt household bulb - then your 1.5 volt battery will not be able to light one of those up at all.Another answerYou can wire any number of 1.5v bulbs in parallel, but for each one you add you will draw more current. Draw too much current and the battery will get hot and may explode, depending on what it is made of.How long the battery will be able to keep the light bulbs lit will depend on the size of the battery, meaning how much charge it can hold. (Its capacity in amp.hours.)
All regular automobile batteries are 12 volts.
It can put out too many volts and destroy the battery but not drain it. The alternator should put out between 13.5 to 16 volts.
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.
Fully charged battery should have 12.6 volts. 75% charged 12.4 volts, 50% charged 12.2 volts, & 25% charged 12.0 volts.
Engine running at idle you should read 13.5 to 15.5 volts.
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.
12 volts with the engine off. 13.5 to 15-5 volts with the engine idling.
With engine running at idle you should read 13.5 to 15.5 volts at the battery.
1.55 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.
A good AA battery has about 1.5 volts across it.
1.5 volts
