Dead Batteries - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I've had 2 dead batteries since I bought my Camaro in 2010. After replacing the battery the engine cranks over slower and slower over time.
I'm wondering if I need a higher amp alternator due to the added strain of the supercharger? Anyone else experiencing this issue or have upgraded the alt or battery?

Hmm, I had a TVS-2300 on the car for 6 yrs and no issue with battery drain due to excess current draw. Sort of sounds like you have a problem with your electrical system that possibly could be detected by someone with the right diagnostic equipment?

Wish I was more help. Keep us posted please.

what kind of batteries? AGM? clean all your grounds and double check all of the aftermarket connections...any codes? try and get a scan and look at the bcm....good luck...

I've been told that living in very hot locations can reduce the life of the battery significantly. I live in Las Vegas and moving to AZ next month so we'll see. There's no corrosion any where on the battery and the clamps were tight. After I move I'll check for current flow on the battery when the car is off.

check your starter connection. could be nasty and not providing the best contact/connection

I had a similar issue and last sunday it decided to just not start. I think a ground slowly got loose somewhere. I ran a new ground and its working just fine again.

It's the stock OEM battery, no codes. I need to look at the supercharger intercooler pump connections.

Any other mods? Taillights, or anything that connects to the OBD connector under the dash?

CamaroFred · 08-26-2017, 12:39 PM

Was an undersized crank pulley included in the supercharger install?

All my mods are HP related. Just the intercooler pump.

I had a similar problem with slow cranking on my supercharged L99, I fitted an MSD Dynaforce starter and problem is solved.
Search MSD starter for my thread.

Do you happen to remember the MSD part number? I didn't find your link.
