Make sure the small wire off the positive terminal of the battery is connected. Check that line for a fuseable link. Sometimes this only looks like regular wire but melts inside the casing.
Assuming the battery is good, you have a short somewhere in the electrical system that is draining your battery. You can confirm this by disconnecting the battery each time it is parked. If that solves problem, a short is confirmed. A professional has the devices to locate the site of the short.
An electrical cord is provided for just that purpose and when plugged into an electrical outlet, the battery charging light will come on. After the unit is fully charged, the Battery Fully Charged light comes on and you can unplug from electrical outlet and use anywhere you need it.
Dead cell in battery or something is on pulling power from the battery. Disconnect the negative battery cable overnight with the battery fully charged (12.6 volts). If the battery is dead the next morning it has a dead cell and needs replacing. If however the battery is still fully charged then a light is on somewhere or a relay is stuck closed.
The basic idea is that electrical energy is converted into chemical energy, which is what the battery stores.
It indicates that your battery is not being charged and that you need to have the electrical system checked.
Electrical Enegy is converted to Chemical Potential Energy
electrical energy into chemical energy
No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
The alternator is part of the electrical system. It is what charges the battery and keeps it charged.
Bad alternator and/or belt. Your battery isn't being re-charged while you run the engine, so the electrical things drain the reserve from the battery.
It could be that the battery is not fully charged or that the battery is incapable of holding a full charge, or that the starter is faulty or that you've just been trying to start the engine for a long time and ran the battery down. Understand that a battery is just an electrical storage device. It only STORES electrical power for use NEXT time you want to start the engine. * If the battery is not fully charged (it didn't get enough electrical energy put back last time it was used), it may not have enough electrical energy to start the engine. * If the battery is going bad, it may not have enough electrical energy to start the engine. * If the starter is going bad, it may pull more energy from the battery than it can provide.
Car batteries are seldom charged by solar energy. Normally, they are charged by the engine of the car, which powers an alternator, providing electrical power.
