hey guys I bought a yellow top battery (model=51) and I heard that I am suppose to use the 51R model (car = 2000 SIR), but when I opened the hood the normal 51 looks exactly like my stock battery, positive and negative were in the same position, is this the right battery or not?

sizewise, unlikely.... our batteries are REALLY small, so a regular Optima doesn't fit in the wee little stock location. Ask BOND007, he should know which one you need. I have a red top in one of the cars, and I know it wouldn't fit in the Civic.

51R is for Honda/Acura...

I was there last month..

The R is for the poles being reversed..

imported_loudsubz

Aaaron is correct, 51R is exactly what you need, but fear not you can still use the 51 you just need to reverse the leads so they fit correctly on the battery.

i swear me and the guy from performance improvements opened my hood and exactly where red and black were on the stock battery, those were the exact places they were on the yellow top, maybe he gave me a 51R who knows, but i specifically remembering him telling me it wasn't a 51R, it was just for a civic, Is there anywhere on the battery where i can check the model number? havent put it in yet, just bought it and put it in my garage, didnt even look at it properly, its pretty heavy though i remembered lifting it

imported_loudsubz

This is all I could find

imported_cbishun

is that the 51R? Because that is the one I have with the red on the right and black on the left

whats so good about these batteries , when compared to like a ct battery or sears brand?

The fact that they are better makes them better

Deep cycling, spill proof gel core, overall just one helluva battery.

imported_loudsubz

and sealed gel cel mean it dont release toxic flamable gases when it charges so its safe to put inside the car with no ventilation

imported_Joker

are they better for audio as well, how do they hold up in sub zero temperatures?

imported_loudsubz

yep

they give you more key off play time for your car audio, and if you drain the battery right down and charge it back up you hurt the battery less than if it was a reg battery

as for cold, i dont think there any diff than reg batteries

BOND007

No problems for me so far and my car has spent many a week with no usage and many at full throttle noise levels....for light flicker either..........still have a stiffening cap just in case

if thats a pic of the 51R then that is the one i have because my positive is on the right, i could swear the guy told me it wasnt but aww well worked out good for me, thanks guys.

imported_cbishun

oh 1 more question but this should be in interior now, i havent installed it yet, i bought the battery and a 1 farad digi cap, will this stop the dimming in my lights? Im running a 1000 Rms amp and a 150 RMS amp, tv, dvd player, playstation.

BOND007

It would help ...cannot guarentee it would stop it completely

might need a stronger alternator, dont know for sure though

A cap is good for occasional hits of base, but it is NOT the end-all solution to your problem. Either upgrade to a bigger alternator or turn down the volume
