I have to replace the battery in my 91. Any recommendations or tips for installation (I assume the lower panel on the fender has to be removed)?

Thanks

 

Correct, you have to remove the panel...

As far as installation tips, it should be a simple swap of batteries.

The only thing i've heard deals with the Optima Batteries... It seems that several members have had to cut one of the posts off the top of the battery to install it properly.. However, the battery installed fine in my 93, without any modifications. So I'm not sure if it's just for specific model years that fellow members have had to remove the post.

 

Here's a link with pictures.

i just done mine on my 92, very easy and i put in an optima red top also the batt store did cut the pos top post off ( due to hitting a bracket) in the mean time he ruined the batt the next am it was dead as hell so he is ordering me a side post only, i paid 95 bucks everyone else wanted 125 to 130 bucks for it

 

What battery would be a direct fit, don't want to cut anything cause I am a mechanical retard!

 

experienced battery replacers will tell you it is an easy process, but in reality, us mechanical retards will be exasperated trying to do something simple on these cars like a battery change. good luck. wait till you have to change a taillight or a headlight!!!

 

Don't get an AC Delco!

Get a name brand, but just not AC Delco, it will fall apart.

 

Buy the best battery you can afford. These cars are battery eaters. I'm on my 3rd battery in 5 years and 25k miles.

 

When my battery crapped out, I went to the Firestone dealer in the next town & bought an 'Interstate' brand. It fit well, no problems.

 

You can always get a nEverstart from walmart. You'll change it out once a year, but you'll never pay for another battery!!!!!!

 

I have had the best luck with Interestate

 

I second the Optima. I have one in everything I own.

I had a huge stereo in my my boat that would drain my dual battery setup in 10 minutes.

Now I can play it for about an hour before having to start the boat.

My wifes summer car ate a battery every year from sitting,,,Optima is 3 years old now fires right up

 

I'll second the Optima and raise your Red top with a Yellow top.

The Yellow is between the Blue and the Red on the scale of starting
power and neglect tolerance. It supposedly doesn't release energy
quite as rapidly as the Red but it tolerates longer times between charges.

I have a Yellow that has sat for long times unused and without
charging - months of neglect in outside storage through sub-zero temps
in a vehicle that sees much less use than my C4.

As for the Delco. I used to have to replace the ones I had in the C4
about once per year. I thought it was going to be the same again with
the current one but it is holding its volts higher between uses and has
lasted much longer than the previous ones.

The only change is that I started using a Schumacher 'Speed Charger'
#SC-1200A battery charger to top up the Delco. I purchased it because
it has different charge modes and was better choice for maintaining the
Optima (when I finally got around to this.) But the Delco seems to
be surviving longer this year with the help of periodic sessions on a
more sophisticated charger than the 2 Amp or variable Amp chargers
I used in the past..

(Note that the 'Speed Charger' requires the negative terminal be
connected to the vehicle chassis or to a length of battery
cable, instead of directly to the battery terminal. Not sure why -
enables the charge sensing feature??)

Edit: As mentioned, my current Optima is in another
non-C4 vehicle.

I was not aware the top terminals can touch chassis
components. This would be show-stopper for me. I
would not try to run it this way and I would not try
to mod the battery.

I looked at Optima's site to see whether they offer a
'side-post only' style. Did not see one, but this was
not an exhaustive search either.

Just make sure it is done right. I highly encourage people NOT to cut the optima batteries because of a problem that I had.
I replaced my battery with an Optima (red top) I had to cut one of the connectors on top off to prevent it from grounding itself on a bracket. Well all was fine for about 3 weeks until it just crapped-out on me. I though for sure it could be anything, except my battery. So I had a flat bed pick-up my car and bring it to a shop where they ran a bunch of tests. Ends up the optima battery had a shorted cell, possibly from cutting the connector. I put an Interstae battery in and haven't had trouble since.

 

Get a group 75 Sears DieHard Gold. Priced right, great guarantee (Sears) and are lighter than the other batteries out there.

 

Somehow I feel left out. I put an Optima red in mine and didn't have to cut posts,shorts or anything. It has lived there for two years now just as happy as a songbird.

 

Theres only 3-4 battery mfgs out there. Brand loyality?

 

i went with the die hard to replace the interstate

 

I have lost count on my headlight swaps. I think five.

 

Finally had time to make the battery swap. Not that hard, but wish I had a better tool selection (took a while to loosen the bolt on the battery tray). Thanks for all the help guys. Now if I can just figure out how to tighten up the top passegers side door panel. Any more help available for this mechanical retard?
