Battery Discharge

Recommended Posts

My 2006 Lexus SC430 battery completely discharges over the course of a 10-14 days. Is this normal? The dealer says the computer causes this and that I should keep a trickle charger attached.

(Fast) discharging depends on some factors. 10 days is a bit on the short side.

- The battery is EOL.

- Something (car-alarm?) is drawing power (parasitic draw). Draw must not be over 25-50 milliamps.

- Battery isn't fully recharged by bad alternator or corroded wiring.

Your dealer (or any qualified electrician or shop), can check above easily.

Had a similar problem with a 05' ES. The battery would discharge over 14 days. Turned out to be a bad cell.
