So quick question, I am trying to figure out the best battery option for my 87 TII. Currently I am running a Optima Red Top that I relocated to the rear compartment. I am not a fan of the Optima as it dies quickly while cranking and doesn't really suit my needs very well. I don't want to run a standard flooded battery inside the car and want to move into something that has a lot of cranking amps and amp hours. The car will sit for days without being started, so I want to figure out a battery that will not die quickly when trying to start it. Plus I'm currently breaking in the motor so extended cranking is normal for now. I'm also going to be running a sound system. Any opinions would be appreciated. Thanks.

 

Maybe an earthX lithium?

Those are a bit rich for my blood. I was thinking $300 or under. But thanks for the reply.

 

In that case I suggest the yellow top. They're better for stereo applications as they have a 20% increase in Amp Hour (charge duration). The trade off is they have 15% less CCA, so not as good in cold winter climates.
That being said, I live in Canada and if you check their reviews on Canadian Tire, most people give them great reviews saying they've lasted 7+ years, and have no problem with intermittent starting (ie left in vehicles parked over winter)
They also come in a variety of CCA ranging from 450 to 900
