You test it with a DC volt meter.
12.6 volts = 100% charge
12.4 volts = 75%
12.2 volts = 50%
12.0 volts = 25%
If it is not holding a 100% charge then it may need replacing.
When it is charging the screen reads: Battery Charging. When it is fully charged it reads: Battery Charged.
The meter on your battery charger will be in the green
i don't care of this question jk ! i don't know i had trouble with this myself. normally you can tell when your iPod shuffle is charging is because the little light will turn orange when it's on the charger and when it's fully charged the light will turn green!
Theirs a battery on the bottom right screen.If it full then that means the battery's fully charged.
Phone off: Your phone will show a full battery and say "Fully Charged" Phone on: on the right top corner your battery will show a full battery and blink
where the battery bar is..it will be fully green
Battery tenders perform a variety of tasks: letting you know whether your battery is charged; letting you know whether your battery has to be replaced; and charging batteries--among many other things.
It wouldnt work
ALTERNATOR OR THE BATTERY GROUND WIRE Have you tried checking your Alternator? I know this is why mine on my vehicle would not stay charged..
how do you know the battery is charged? also it could be a loose battery wire. they need to be properly thighten so the energy could flow. if there are no lights theres no power coming from the battery.
The light instead of being orange becomes green.
Test the battery with a digital voltmeter. You should get a reading of 12.6 V if the battery is fully charged. If the battery is fully charged then you know the alternator is functioning properly and your problem is more than likely a defective starter.
