Try the charger again at a friends house, if that doesn't work contact the supplier for a warranty claim, or if out of warranty you may have to purchase a new one. Many different kinds of chargers can be found on Ebay for reasonable prices.
You need to buy a new battery look up which battery works with your laptop and buy it online
Shut the charger off when you plug the charger into the battery. The low charge on the battery will cause arcing when brought into contact with the charger. If the arcing continues with the charger shut off check the diode bridge in the charger, there may be a blown diode gone to ground. Make sure that the output of the charger is smooth DC at the proper voltage output. If there is a problem with the battery, the over load protection on the charger will trip due to excessive current draw by a faulty battery.
Depends on your charger. If it can handle 230v, there should not be a problem. It should say on charger, for example 110-240v. And remember to bring a travel adaptor, if the charger don't have a EU-plug.
Too much current was flowing which caused an overheating problem. Can be the battery has a dead cell, or you reversed the cables.
There are two possibilities, either you have a defective charger or an old battery. Try charging it with another charger to see if it solves your problem; If not, it may be time for a battery replacement.
You should consult a cellphone repair expert for a device inspection
It is normal for battery chargers to get warm while in use due to the energy conversion process. However, if the charger becomes excessively hot to the touch, it could indicate a problem with the charger or the battery, and it should be unplugged and inspected for safety.
If you know it is the battery then try using a charger to charge the battery, make sure that you clean the battery connection terminals. If the battery will not take a charge from a charger then replace it, if a battery gets too dead it can't be revived. Also, have your alternator checked before driving if you didn't cause the problem with sitting or leaving the lights on etc.
You can wreck the battery. Get a smart charger or trickle charger to avoid this problem.
I would suspect the battery has been discharged, is defective, or you have loose or corroded battery terminals. Remove and clean the terminals and if that does not solve the problem charge the battery with a battery charger. If it will not take a charge then replace the battery.
As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it). The real issue is now fast the charger is draining the battery. BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).
You can hook up a battery and 240v 12v heavy duty charger system,that is the easiest way to get over that problem. The charger has to deliver enough amperage to cover the load from the winch.RegardsJohn Cas
