Replacing Battery on 07 camry

[cptdar.se07]

Im planning on replacing my stock battery becuz it seems too weak for my sound system. If I bump for 15 mins I have to jump start my car. I have an amp hooked up to my 15 inch kicker n another amp to my four 6x9s. Any suggestions? I was thinking of getting the yellow optima battery... any drawbacks that u guys know about? How much would a capacitor help? Cuz sum guy at a sound shop told me they dont do much to just buy a better battery. Any help would be greatly appreciated....thanks!

Get a better battery or add a secondary battery. The benefits of a cap are debated, but doesn't do anything to reduce power consumption of your system or increase available charge in the battery.

I would suggest a higher output generator, sounds like you are drawing more current than the charging system can replace. Could be your charging system is just weak.

I'd recommend an Optima yellow top battery.

It wouldn't be a bad idea to verify that the alternator is working properly also (you don't actually have a generator).

I do have yellow top and it is weaker than the OEM battery. Reason I have it is so I don't have to change the batt for a long long time.

What U need to look at when it come to battery is the CCA. The higher the better. And as the batt get old this # falls. Anyway, when I was replacing my batt I did notice the yellow top has less CCA than the OEM.

After replacing with the yellow top, my start up is weaker.

What OP need is a stronger/higher CCA battery because it sound like he play his music while the engine was off. OEM battery is already pretty high so might have problem finding a higher 1. Cap only help with even out the power drain. So look like the only solution is 2 batteries.

Here is pic when I install my HID. U can see the yellow top in there.

If you are going to sit around and run a high drain device on the electrical system, you would be much better off locating a second battery in the trunk, isolate it so it can be charged by the alternator, and run the device from it. Your car's battery was never designed for such things and is really rough on its longevity. You can probably find a battery isolator at Pep Boys for cheap.

Actually, for the purposes that the OP outlined the CCA of the battery isn't nearly as important as the RC (reserve capacity). Of course, you also need a battery that does provide the correct CA's and CCA's.

So whats it like providing the sound for Metalicca concerts with your Camry lol. I'd go with the other peoples advice, two batteries; one in the trunk (the only place it will probably fit); alost certainly you'd want an optima back there, not a regular old lead-acid type (acid fumes and hydrogen gas in your trunk - bad).
Also i think i'd ask an electrician what size (gauge i.e. thickness) cables to use before i made them up, because there is going to be a large power drop from you spare battery in that long cable run. The cables will have to be relatively thick to make it work as you can imagine.

As far as a cap, the only thing it will get you is a smoother peak/valley delta by storing power to be utilized in peak requirement times (like big bass hits through the amp) when the amperage needed spikes.

Dumb question, but was the car running during those 15 minutes? You said you were playing music and needed a jump but didn't specify if the car was running and cut off or you were simply using the Camry as a sound system without it running.

R U saying it is possible to drain the power so much that the engine dies while running with a good alternator?

It is possible, but I doubt he has such a system. That said, I can't believe that someone with a respectable after market audio system would:

A: Not invest in upgraded power systems
B: Run it at full tilt for 15 minutes without starting the engine and letting the alternator and charging system do their jobs.

A: Run out of $
B: Gas too expensive.

Gotta pay to play. If you can't afford to do it right, don't do it at all....

[krouchchocolate]

Probably best to invest in a HO alternator, and do the big 3 while you are at it.

Thanks for eveyrbodys input...I meant 15 mins or more with the music playing n the car off...i think for now Im gonna go ahead and buy an optima battery
