there is a little light on the charger cable that will light up red while its chargeing and green when its completely charged
Laptops that's battery is fully charged does not weigh any more or less than one that's battery is not fully charged. If there is a difference, it would be so small you would not be able to tell.
You can tell that an electroscope is charged by observing the divergence of the leaves. If the leaves spread apart after bringing a charged object close to the electroscope, it indicates that the electroscope has acquired a charge.
look in the top right corner of ur pantech matrix. as u see it looks like a battery if the baterry is all blue it has full charge
i think it wont glow .
There are two measures, cell voltage and specific gravity of the electrolyte. Cell voltage is the simplest to measure. For most automotive, flooded cell (having liquid electrolyte) batteries, 12.6 volts is considered full charge, although it is typical to have 13 volts or a bit over. The specific gravity of a fully charged battery, measured with a hydrometer, is 1.265.
ummm, i would just put brand new batteries in it i dont know any other way to know for a fact that it is fully charged :/
Ask a teacher
If you want to know the voltage of any battery you need a volt meter. These can be as cheap as 15- hundreds of dollars. Knowing the voltage still doesn't tell you if a rechargable battery is fully charged or not. a charger with an indicater can tell you that.
A proton has a positive charge and a neutron has a negative. The nutron travels in shells around the nucleus. this is what the bonding in a compound uses - convalent and ionic bonding. The ratio between the protons and the neutrons tell us whether something is postively charged or negatively charged.
You can tell the RAVpower deluxe RP-PB35 is fully charged by checking the LED indicator lights on the device. When fully charged, the lights will typically display a solid green light or all four indicator lights will be illuminated, depending on the model. If the lights are blinking or showing red, it indicates that the power bank is still charging or not fully charged. Always refer to the user manual for specific indicator meanings.
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.
First use a digital volt meter to check the voltage at the battery with the engine not running. You should read 12.6 volts DC if the battery is fully charged, 12.4 at 75% charge, 12.2 at 50% charge, 12.0 at 25% charge, anything less and the battery is, for all intents and purposes, dead. If it does not have enough charge to start the engine fully charge it with a battery charger. If it will not take a charge it is defective. Once charged start the engine. You should read 13.5 to 15.5 volts at the battery with the engine running. If you read less than 13.5 volts the alternator is suspect and more than likely defective. Or you can just drive the car to your nearest auto parts store where most will check the system for free.
