How the ^&&% do you remove the battery ? Does the engine need to come out first or is there a special tool ?


Mine (2011) has died and I have a replacement AGM on order but need to get the old one out. How ?! YWTK

 

Really a routine task without any major issues to remove (IMO). After you remove the battery hold down nut, rotate the hold down strap towards car front so it comes loose from the mount near the fender. Once the battery hold down strap is removed, you'll have to move the battery slightly towards car front so it comes out from under the tray's back edge where the battery is held secure. See attached page from Service Manual.

Hope this helps,

 

Space is tight, for sure. No special tool. Look closely, there are handles on many batteries that are not immediately visible. Otherwise, got to pull straight up��

 

Good point. Nearly all the batteries for these cars have handles built in that are typically folded down. One just has to look for them. See attached file.

 

If you have no handles then you could use one of those straps that pick up the battery by fitting on the battery posts.
In your case you could use a Sawzall and a hose to wash away the acid.

 

Be nice!

 

hat's right, you're wrong. Service replacement MOPAR 72 and no handles fitting tight. Used to have a lifter that went over the posts but cannot find. Of course that was thutty yar ago. Guess I need to buy one.

 

junk battery = 2 pairs of vice grips. Job done.
( and it's 30 yarns ago, not 30 yar ago [ Battlestar Galactica ] )

 

OMG, really? He he he I hope no one really 'grabs' a super high amperage battery with 2 vice-grips...

Hi George! LOL

First, raise the hood 'vertical', then take off the NEGATIVE terminal FIRST, hide it below the top of the battery (so it doesn't make 'casual' contact). Then remove the POSITIVE terminal. Find a way to lift the battery that DOES NOT involve using anything that could 'short' the terminals against each other. Like previously posted, most of our replacements have a handle on them BUT if your replacement does not, utilize the place you bought it from as they (for the most part) have that 'strap' or someone who can do it for you. REMEMBER to take your 'gas/vapor' part off the top right side of old battery to install on the new one. This part is usually found below the battery somewhere, as it pops off and falls below the battery. If it is still on the old battery, it'll pop off. The new battery should have a 'hole' for it to be popped back on (it may be a little 'nipple' plug that comes out so you can put the vent in). This part helps 'vent' the gasses produced naturally in the battery, safely. I do not know if those AGM batteries have those vent holes, as I do not buy them at all so no experience with them and the 'vent' either needed or not). Then you connect your POSITIVE cable FIRST and then the NEGATIVE cable.

 

You are absolutely correct GG, I was just giving good ole Alabama shade tree advise.
( didn't think of the possibility of the 2 vise-grips coming together )

EDIT !!!! - just use ONE vice-grip on the negative post !!!!!

BTW, I have an East Penn AGM, it has the vent holes both front and rear.

 

Every battery that I have seen had a vent hole at each end, a plug goes in one and a vent trap or vent hose goes in the other. which end the plug goes in depends on the layout.

 

Thanks for that Dave, I get to plug a hole instead of ordering another of those $5 vent tube setups.

 

Yes, exactly. When they are PRODUCED, they have the plug available for each hole (or attached in some way). When installed, they are set up according to how it is installed. When you have a vent of any kind (some have a vent box AND a hose, which vents away from the battery). Many times during transit (and consumers who do not know what they are) they get lost, discarded, or not used after purchase.


George, If you do not have the vent, please do not plug the hole in the battery. That builds up pressure in the battery depending on its charging system. It also is designed to 'equalize' the internal and external pressures in the battery and surrounding climate. If plugged, it does neither.

 

Just to be sure that I had a plug in the end against the firewall L moved the battery forward and looked. There is a plug in there.
I slow charged up the OEM Varta yesterday, still appears to be OK after all this time, it was made in 2004. I would not want rely on too much though.

 

And the FSM says "

1. Disconnect the negative battery cable (4). If necessary, use a battery terminal puller to remove the terminal clamp from the battery post.
2. Remove the protective plastic cap (1).
3. Disconnect the positive battery cable (2). If necessary, use a battery terminal puller to remove the terminal clamp from the battery post.
4. Remove the battery hold down nut (3) and strap from the battery.
5. Remove the battery (5) from the battery tray. "


but says nothing about the clamp on the firewall end (see pic.)


Wound up going to local Boyz with Vigor and found a carry clamp with narrow enough ends that could slip on sides - wanted one that was just a strap with holes that gow over the battery terminals but would have taken two days.


Was able to rotate the battery on end and lift out. (New one has handles) and then I saw what looks like a clamp on the end but not sure there is room for a socket and extension between the battery and the firewall to tighten so just going to leave in place.


Even my 150 Jag was easier and it had two 6v batteries, one in each fenderwell. (remove the liner to reach).


But haven't had to replace the one in the GTP yet. Is under the windshield washer reservoir.

 

That may just provide a lip for the battery to go under, no unclamping necessary, my new battery does not have a lip and the OEM Varta does. It possibly just holds down the end of the battery tray.
I think I remember the old Varta sliding forward a little to get out from under a lip. I have the old Varta but I am not going to refit it for a test. My new battery has a lip at the negative end only.
This battery is very easy to get out, take off the terminals, unscrew the clamp and lift out.
It was much easier to get the batteries out of the Rolls, I just told James the chauffeur to handle it.
He's gone now, I found him playing around with the housemaid, he knew I always handled that.

 

Something really odd about this thread - can't put my finger on it...

 

Could put finger on it, just couldn't lift that way. Once rotated and stood on end I could lift it out.

 

This is my recollection when I changed the battery earlier this year. I didn't even know there was a bolted-in clamp near the firewall. Maybe I learned another new thing today! Been on a roll lately!

 

And that would be because there is not, at least in my experience and I have worked on at least 12 different Crossfires and never seen a rear battery clamp. There is, however, a notch at the rear of the battery tray where an extension of a battery could fit.
