Odyssey battery

[510-SR20DET]

I just bought an Odyssey PC 545MJ battery. This little thing has 545 cranking amp for 5 second. I thought it should be enough to crank my s14 sr but the shop said it TOO SMALL? o.O
Are they right? i mean it has more power than the stock batt wtf. I dont want to get a hugh power batt cause it will be a pain to jump start that batt.
please give me some input

I have an S14 SR on S13 chassis if that really matters. I use the $40 Autozone Lawn & Garden battery with 310 cranking amps and works just fine. So you should be good. GL !!!

it'll work fine but will put stress on your alternator eventually. esp if you have a sub and a couple amps.

try charging it it may just be low voltage form storage

I dont even have speakers LOL. Its relocated in the trunk tho. does it matter?

I have a dinky Braille battery and it works just fine on my SR even when it's freezing outside.

lol i have a odyssey pc680 and it cranks just fine.

i thought PC 680 is a little over power to crank a 4 cylinders to i picked PC545, a little close to stock batt.

you guys are looking at battery specs optimistically as opposed to realistically

the odyssey battery specs are all typically listed under ideal conditions, fully charged, pulsed cranking amps, etc.

put the weight loss into more important parts of the car (unsprung) and use a decent sized battery. ive got a pc1200 and prior to that used an optima D900M. the optima has been working for near a decade and the odyssey was purchased last year.

if you buy a undersized battery and use it inappropriately, the mfg wont want to warranty it. readup on the nsx forums, guys were running into warranty problems trying to replace their undersized batteries because like here, they were too concerned with weight loss and ideal specs, as opposed to real life situations.

as for relocated setups, voltage drop is something important that should be considered when modifying your system. engineer things properly.

I've been running a small battery and had issues when it sat for more than 2-3 weeks without starting. I've since installed one of CodyAce's quest alternator brackets (115 amps, beats the heck outa the stock 75) and haven't had an issue now keeping it fully charged. I think my main issue was that HID's and other components were to much for the factory alternator, which then drained the small one. With the bigger Alternator, it works just like it should.

Sure I could have ran a large battery in the trunk, but I opted for the kit and alternator, as it was cheaper and didn't require all of the extra hold downs and wire to the back.

HID uses less power then stock healights.
Do you guys think cable play big role on this, since i relocated to the rear? The previous owner used some red cable use for sound system but i dont understand it, sound system required alot power like 1000watt i see some that even 2000watt o.O

^ Electrical cable GA plays a huge role with current transfer over distance; what size are you even using? There are standards for wattage capabilies for stranded copper cable; look around on google for some graphs.
