I keep killing optima red top batteries

[Jr]

Hi guys,

I need help figuring out how/why I keep killing optimas.

The car:
1967 Camaro
New aaw wiring
Ls with lsa blower.
Bosch intercooler pump. Pump stops working when key is off.
Anvil light bar headlights
Holley dash/ dominator ecu
Vaporworx fuel module
Zl1 pump.

Where should I start looking? Could it be a bad ground? Is something still “on” even though the key is off?

Have you tested for parasitic battery drain?

No, but I will.

cjfirstgen is giving good info.
I had the parasitic drain problem on my 69 Camaro,
finally found it of all things the clock in the stereo!!
It took a while for the battery to drain but over time
setting in the garage the car wouldn't't crank.

Define killing. Is it discharged or is it damaged and not chargeable?

Are you using the correct charger for Optima batteries?

Parasitic drain.
I had the same exact problem on my 68 Camaro and found two leaks from my fuel injection and transmission computers. Since both loads have to bypass my disconnect switch and go directly to the lead of the battery, I decided to change out my red top Optima and install an Odyssey battery.
Problem solved. Odyssey batteries rule!

Dead/discharged not damaged. This is the 4th optima I’ve put into the car in 4 years.
