original battery failed, then two/three months after new battery was installed, car would not start. when put on battery charger, quickly starts and may last for a week or so. then after sitting overnight, will not start. After charged, the battery shows to be charged and so the alternator. there is no corrosion on the posts or any where.

If we have a medical emergency, I won't want to have to charge this crate to get to the dr.
