1. My car has been sitting for awhile, but it has started up when I needed it to.
I recently took out and put back the transmission. I got everything hooked up and the car would not start. I took a reading across the battery terminals and got 11.87 volts. Is this an indication of a dead battery?

2. I should mention that I unhooked the positive and negative terminals while the trans was out. I also have a battery disconnect on the negative terminal (turn a screw to connect/disconnect). I got sparks when I hooked up the positive and touched the wrench to the car accidentally.

3. I have an Optima Red Top battery that is only about 1-2 years old.

4. I checked all the wire connections related to the trans and didn't see anything. That shouldn't matter anyway, I think.

5. I'm thinking of jump-starting the car and seeing if that works.

6. I'm also thinking of getting a battery charger and hooking that up.

Thoughts?

A dead cell would make it 10.5v. That just sounds low -- in need of charging.

Optimas hate cheap chargers. Spend the $50+ on a smart charger with trickle.

A battery at rest will hover around 12.5v
