I've had my 51R for only 15 months. Went to start it up tonight and it first started to turn over fine. All of a sudden, it acts like a cell went bad. Now it won't accept a charge.

Gotta pull the blower this weekend to change the plugs anyways so I guess I get to do it all in one shot.

 

ive had mine for 2 years so far and no trouble

 

I was talking to a shop and they said they were having problems with the Yellow Top not lasting very long. They said SVR is much better.

 

Svr?

I have a Yellow Top too, I was told this just a week ago.

 

Nothing beats a good ole Sear Interstate battery.......

 

Who else makes a Glass Mat or Gell Cell battery? I want something sealed and don't want to mess with acid.

 

Did you check out that SVR site?

 

Odyssey Batteries...

 

pulling the blower out used to piss me off soo much!

 

These Optima batteries arent a good as they are cracked up to be, I am probably on my 5th one in a matter of 4 years. As a matter of fact, I just replaced my red top yesterday

 

01blac:
Do you have stock in Optima ?

 

hm. i think ill add one of those svr's in addition to my yellowtop

 

Die Hard 4 Years Now

 

Didn't see one that would work

 

You're ahead of me as usual Dustin. I was checking out the Odyssey PCT1200T

Optima Yellow Top 51R:
500CCA
(L X W X H) = 9-5/16" X 5-1/16" X 8-15/16"
Weight = 26lbs.
Reserve Capacity = 70

Odyssey PCT1200T
630CCA
(L X W X H) = 7-13/16" X 6-9/16" X 7-9/16"
Weight = 38.2lbs.
Reserve Capacity = 78 w/ 25amp load

Odyssey is 1.5" wider which may be an issue. I'll have to see if I can modify the Comptech Battery tray to accomodate the 6-9/16" width. Mil Spec battery is definitely a plus. I'm also surprised the the Odyssey is 12lbs heavier.

 

I had to change out the Red Top of my 300ZX last month too. I think it only had 30 months.

 

SVR 34 Sealed AGM Battery

Looks like a good battery but a bit bigger than the Odyssey. I'm going to have to modify the Comptech battery tray as it is and the additional length plus the additional width won't work. I think the Odyssey PC1200T will work with less modification to the tray.

 

I forgot you have a S/C.

 

Placed an order through West Coast Batteries. The guy convinced me to try this one:

It should mount in with no major modifications to the battery tray and he's sending it with battery posts. He tells me that he runs one of these in his Ford Truck. Higher Cranking amps but lower CCA than the Optima 51R. He tells me that there are a lot of guys using this battery around his shop. My jaw dropped when he told me it was for a Harley Davidson

 

<--- Acura 51R battery. Going strong at 30K miles

and FYI you don't need to pull the blower to remove the battery. Remove the intake plumbing, disconnect the cables and bracket, then slide the battery out towards the firewall.

 

Cool, can't wait to see your review on this. One more question, how exactly do you conncet the cables to this battery?

 

With the battery posts that the guy said he is sending him.

 

Probably a lot of good flooded lead cell batteries out there. Call me Anal but I like the cleanliness of a good sealed battery. I'm not real regular on cleaning acid as I should be.

It's actually good timing for this to happen. Going to lift out the blower and do the plugs at the same time. Also picked up a Comptech strut bar that I need to install so perfect for getting those rear plugs out.
