I left my lights on all night

Recommended Posts

99 C2

Hi all, last night i left my lights on. This evening when i came back to the car the lights were still on. For a total of about 18 hours. My friend and I tried to jump the car using his toyota corolla but it will not turn over. The voltage meter in the car reads 10.

Any advice on how to get my car up and running again.

Definitely a battery charger, they are really cheap and worthwhile having in the garage. I'm a bit surprised however that the sound alarm did not remind you to switch off the lights when you opened the door to get out of the car with the engine switched off.

When jump starting make sure the other car is running. And let it run for a while to give your battery some charge. The high impedance between the terminals of a dead battery can cause your car to stall.

Once your car is started, leave it connected to the other (running) car for at least 10 minutes. Then leave your car running for at least another 20 minutes. The alternator in your car is a battery charger but it only works when your car is running.

To avoid this in the future, consider getting a Priority Start! device. It plugs into your battery & will shut it down if you leave the lights on. I bought one for my 986 because I didn't like the whole no access to the hood when the battery dies thing. Install is 5 mins, and it could save you this headache next time. I think it's prioritystart.com or something and you can get them at Performance products or on eBay.
