Some car battery charges will not charge a completely dead battery. You need to find a type of battery charger that is designed to charge a completely dead battery. You can get around this by hooking a car with a working battery up to the dead battery with jumper cables. The alternator/charging system of the car with the good battery will charge the dead battery. Leave them connected for about 30 min, then disconnect and try to use the battery charger again. If it still won't charge, hook it up to the car with the good battery for a longer period of time.

The car has been left standing for 3 months and will not start no ignition light on the dashboard?

It is very common for the battery to discharge on a vehicle sitting idle for 3 months. First disconnect the positive + & negative- battery cables, and clean the battery post and cable connections off. Apply a thin layer of dielectric grease or Vaseline to the battery post and connect the negative - cable. Put a battery charger on the battery and let it fully charge overnight. If it will not accept a charge it is defective. It it does show fully charged, connect the positive + cable and see if the engine will start. if not, then more than likely the battery is dead and needs replacing.

How does a lawnmower charge a battery?

I suppose you're referring to a riding mower. As you didn't specify the age, make, etc, this will be an educated guess. If the mower is kept in a controlled environment, such as a garage with heat during the winter months, the battery should hold charge for years. If it is kept in a shed outside, then you'll probably need to charge the mower's battery every spring. All you need is a battery charger with jumper cables. Make sure it is capable of charging you're mower's battery. The battery is charged by a generator or magneto. It is located under the flywheel.

Gel batteries for vehicles are not inteded to be left for an extended period of time without at least a tricle charge. The best way to see if it is still any good is to put it on a charger that produces 1/1000th of the batteries amp rating and leave it there for 48 hours. this extremely slow charge will keep the battery from exploding and can re-excite the battery's chemical reaction.

Can be a dead cell in the battery which will fully discharge the battery over night. The battery must be replaced. Of course any battery will loose it's charge over a few months of storage.

How do you keep your car battery from going dead after 4 months?

Maintaining Battery ChargeYou didn't say, so I have to assume by the "4 months" you mean you mean without starting, running, and using the vehicle.It that's the case, then it is not uncommon for most batteries to "self-discharge" over that time period. There are a few ways to maintain the battery's charge:Start the vehicle about once every two weeks, and allow it to idle for about 10 to 15 minutes. This will allow the alternator to charge the battery, and allow time for the engine and coolant to fully heat up to normal operating temperature, and circulate lubricating oil throughout the engine which will help protect the engine's internal parts from corrosion.If you don't want to start and run the engine, then you can buy a small, inexpensive charger designed just for keeping the battery charged. This type of charger is called a "Trickle Charger"and puts out just enough current [about one Ampere (Amp)] just to maintain an already fully charged battery.You could also use an ordinary battery charger IF it hasa trickle charge mode of operation.Another option is to buy a Solar Trickle Charger [uses Photovoltaic cells]. With the solar trickle charger you just plug it into the cigarette lighter socket and then lay solar cell panel on top of the dashboard where it can get at least a few hours of sunlight daily.

I would not buy one that is over 6 months old. But the shelf life is at least a year. After the battery sits on the shelf for over 3 months it is a good idea to charge it before putting it into service.

Can you over charge your cell phone?

The phone itself will not be damaged. Once the charge is completed it will stop charging the phone. It can damage the battery though. If your phone is only half way down on the battery and you plug it in, the phone retains that memory. Once in a while it really doesn't matter but if you are constantly charging your phone every day when the battery isn't in real need of it, eventually the battery will go bad. It may even get to the point where it won't charge at all for you anymore. The general rule of thumb is to let your phone die completely about once a month to keep the battery fresh. What I would recommend though, is not charging your phone every day. Let the battery wear down. Buy a car charger so that you can charge it while driving if it needs to be. This will save you from buying a new battery every 9-12 months. New battery's usually cost around $50.
