Top Causes of Overnight Battery Drain
Understanding why a battery won’t hold a charge can save you from being stranded. ER Autocare identifies these common causes:
Parasitic Drain
Interior lights, dashboard modules, or infotainment systems may pull power even when the engine is off.
Old Battery
Most batteries last 3–5 years. Older batteries, especially in colder areas like Polaris, may fail overnight.
Faulty Alternator
A malfunctioning alternator can’t recharge the battery while driving, causing overnight drain.
Corroded Terminals
Buildup interferes with energy flow and leads to slow discharge.
Left-On Accessories
Headlights, chargers, or interior lights left on can deplete even a new battery.
ER Autocare uses advanced diagnostics at our Columbus and Dublin locations to pinpoint exactly what’s draining your battery.
