Car wasn't used a whole day Saturday from Friday 6pm, went for a few small drives last night not more than 10 minutes each , this morning it was DEAD !, I have emergency lights and sirens installed and the amp draw after shutdown is from 0.136-0.101, is this enough to kill the battery , after how many hours ? The lights have been installed for 3 months and have never given me any problems Should I go with Optima battery ? The red or the yellowone ?
Thanks

Yellow top is best for your kind of set up. You may also want to put a on/off power disconnect switch to your emergency equipment (that way you can kill any power consumption to your emergeny equip at the flick of a switch). LED lights draw the least amount of current if you did not know that already. I would like to see of pic of you setup. Good Luck - Engine 2

There is a battery drain down recall on 07 Subs. Not sure if it is on all, but I know it was on 2500's. Check with your dealer... It's a computer flash I believe.

Just had my 2007 Tahoein the shop this morning to have the tires balanced, and they updated the computer due to the battery drain issue it was causing.
