Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. The concern you are having could be as simple as having a battery that cannot accept or sustain a charge. Have the battery checked professionally first. If the battery should test good, then further testing Is needed of the charging system - is the vehicle alternator able to recharge the battery sufficiently? If that is good, then you may want to check for a parasitic drain of the battery while the vehicle is off. If an energy drawing component is "awake" while the vehicle iso off, the battery could become run down. Hands on testing as demonstrated above is needed.
