I need help. My lotus was sitting for a week with cut-off switch on OFF. Decided to drive it for one day. Then it sat for 2 days without driving it, the following day I decided to use the car but the car wouldn't start. So, I decided to jumpstart it and started fine and the next day it wouldn't again therefore I once again did a jumpstart, started fine and used it all day. Now, tried starting it today but wouldn't start. I've had this braille battery for 3-4 yrs now.
