Car is killing batteries, pulling 1.2 amps all the time.


Recommended Posts

I am having a hard time with batteries in my 2007 Boxster. Car is completely stock, no added electronics. I recently installed a new Interstate battery only to have is die in two short weeks without drving the car. The voltage dropped to 4 volts.

Today I installed a new Optima battery 34R. Before hooking up the negative terminal I checked the parasitic amp draw. I removed the front boot light to get an accurate reading. The car draws 1.2 amps continuous. That seems pretty high but is this normal and also the reason we all need to trickle our 987's non stop?

Put your amp meter in series with the battery and then pull one fuse at a time until you see the current draw drop.

Once you do that you will at least know what circuit the draw is in.

Get back to us when you find the circuit.

Neat trick!! :) thx for the info
