Should the charger be removed after the laptop battery been fully charged?

Well technically speaking yes, because the battery can over charge, lowering its life span/capacity and the adapters tend to overheat causing damage to the charger. Fortunately for the newer laptop batteries and chargers this problem is solved. If you are really concerned about either of these events occurring then unplug it after each charge.

What reading on a battery charger will indicate the battery is charged fully?
If the charger has a ammeter on it then it should show close to zero which means the battery is no longer pulling any current from the charger which would mean the battery is fully charged. If it has only a voltmeter then it should show 12.5-13.5 vdc
How Long Should You Charge a Motorcycle 6 Volt Battery?
Depends how flat it is and the capacity of the charger and also capacity of the battery. A 6 volt battery fully charged should read about 6.5 to 7 volts when fully charged.
What should battery charger needle read?
That depends on the battery, and the charger. my charger has different settings for higher amps to give a faster charge or jump. A fully charged battery will show 12.6 volts. The charger will read it's maximum amperage if the battery is totally discharged. A fully charged battery will read 12.6 volts with a digital DC volt meter. If it reads 12 volts it has less than 25% charge.
Should house batteries be removed from an RV during winter shut down?
As long as you keep them charged you do not have to remove them. A fully charged battery will not freeze, but a dead battery will.
Should you disconnect a car battery when car is not used for a few months?
Yes, this will prevent the clock from running it down. You can also install a trickle charger to keep it charged. A battery with no charge will freeze. Keep it charged and it will not freeze.
How do you charge battery with ac power supply I have a 12 volt dc battery and im trying to charge it with a power supply rated at 0-40 volts 0-5 amps?
You should charge the battery with the proper battery charger. The battery charger should list what types of batteries, voltages, and charge rates (amps) it is compatible with. Make sure this matches the information on the battery to be charged. Using the incorrect battery charger can cause battery explosion, leaking, or fire.
Can I charge a US camera battery when in the UK?
The battery for US and UK is the same but the different is the battery charger You should get a UK charger for you battery.
Does leaving a battery in a charger after fullt charged damage the battery?
Yes and no. Yes it will damage the life and rechargeability of the battery if its a normal streight through charger. No- if your battery charger has a trinkle charge on it. Trinkle charging is when a battery is fully charged and the charger recognizes this and stops charging and allows the battery to loose some charge and then repeat the process, instead of continuosly shoving power into the battery. Some chargers and most new chargers have this feature built in. And some will say this on the charger itself. But the majority of chargers do not have this feature and you should take the battery off and either let it sit or use the battery until its almost or better yet all the way dead. That is the best way to keep your battery memory fresh and make it last. BIGJ
What should you do if battery was not charged before installing new alternator?
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
What is the difference between battery charger and intelligent battery charger?
a simple battery charger only charges the battery and having no feedback from the battery status, it can cause overcharging, increase temperature, and can damage the battery or in worst case can blow up the battery, also mitigates the life time of the battery. whether intelligent battery charger charges the battery and get feedback from the battery , when the battery gets fully charged it Cut off the charging circuit itself, also maintain the charging at its trickling current to control the temperature. simply it shows the status of the battery. i hope its the Good answer. thanks although the intelligent battery charger charges the battery and get feedback from the battery,the batteries have different charge characteristics. For example ,some intelligent battery charger detect △V and △T to control charge. However when batteries has been charged fully,they will show different characteristics. some battery has show the voltage dropped,but in fact they has not been charged fully,even charged a little just because the wave input voltage.some batteries has show the voltage dropped,but the batteries has charged fully for a long time.So acccording to the △V not to determine the fully charged.△T has the same problem and when the same battery charged fully will come different temperature,if the charging current is different. So △T is worse than the △V. Finally,although the intelligent battery charger can get feedback,now the battery charge characteristic is unsure.So it is no sense. I think battery charge should be distinction by constants current or constants voltage.they will produce obvious different effect of charge.
How long does it take to charge a lawn mower battery?
With a 10 amp charge about 1 hour if the battery is totally dead. You should really use an automatic battery charger that shuts off when the battery is fully charged to avoid overcharging.
How long should you charger a 7.2 battery with a 9.6 volt charger?
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
