You need to take the time to put some punctuation in that really huge sentence, otherwise it can be read at least three different ways. I DO understand the engine won't start with what could be a seven-year-old battery. Suspect it has a shorted cell and must be replaced. You can verify that by measuring its voltage. A fully charged battery will read 12.6 volts. If it's closer to 12.2 volts it's okay but discharged. If it has a shorted cell, it will be around 11 volts or less.
