Do Remote Starters Drain Battery. Two very good possibilities are the battery and the starter. Recharged the battery during the day next AM it was dead again went to the shop and had them disconnect the remote start they said it could not.
If the battery remains charged you. I narrowed it down to the remote start system the installer put in. Only time will tell.
All remote starters whether from Compustar Arctic Start or another brand draw power from your battery.
Worked Great for 2 weeks no problems. What I did was disconnect the brain and let it sit. Parasitic drain is due to components in your vehicle continuing to run after the key is turned off. If it starts its probably the battery.
