Hunters21w Posted November 11, 2009 Report Posted November 11, 2009 Well Im working on buying a battery until I can get an alt around xmas. What should I look for in a battery? I heard amp hours is good to know? I found a C&D battery that weighs 100 pounds, 134 ah and is supposedly equivalent to a kinetik 3800 An optima yellow top that is 100 ah, g31 I believe. or a kinetik 1400 which is 60 ah. What are your opinions on these batteries? Need somethin to help run an RD 3250 v2 until I get an alt.

CaptainzPlanetz Posted November 11, 2009 Report Posted November 11, 2009 Is this to go under the hood or in the trunk? When under the hood you have size limitations most of the time.....even with cutting, but if it is for the trunk I would get the biggest battery you can fit back there.

AI James Posted November 11, 2009 Report Posted November 11, 2009 buy the biggest one you can fit of the 3 even if it didnt fit up front id run the C&D as a secondary battery Quote
Hunters21w Posted November 11, 2009 Author Report Posted November 11, 2009 Yea it will be in the trunk. No size limit Idk which battery I should get tho, some opinions plz.

Hunters21w Posted November 11, 2009 Author Report Posted November 11, 2009 is that what matters the most? isnt there a formula to figure out what size battery you need in watts? sorry, still learning Quote 06 Police TahoeHU- Pioneer 80prsAmp- Crossfire 8kSub- 4 15" Crossfire xs v2sWire- 1/0 Knu/AudiotechnixAlt- 3 Mechman SMD 340sBatts- 6 XS Power 3100s, 2400

P4killer_ Posted November 11, 2009 Report Posted November 11, 2009 From what I have read. And stuff ah is what matters and so as a rough guidelines multiply your voltage bybthe ah rating for about how many Watts it can support. If you have stock elctrical 13v * the ah should be okay. Where i get confused is what ah rating to use . I saw in a tut video in the. Hifonics section Some people don't agree with this approach but never seem to explain why Good luck Quote Setup: 2010 Hyundai Elantra Factory Unit via 4 chan NVX LOC Excessive Amperage "H/O" Alt Xs D3400/ Xs XP3000 Big 3. 2 Runs of +, 2 Runs of - DD M3b and 2 12" AQ HDC4s
Hunters21w Posted November 11, 2009 Author Report Posted November 11, 2009 Yea I just watched both vids. So I would say the 134 ah would be the best to go. That would give me 1742w at 13v. My alt is 140 stock. So subtract 40% from that would give me 84 amps with my alt left. So then do I multiply 84 amps by 13v? to get my alt output? If so, that would give me 1092. so 1742 + 1092=2834 If my amp is 80% efficient then it would be 3000 x .8=2400 right? So theoretically would I be good? Let me know if I did something wrong, thanks Quote 06 Police TahoeHU- Pioneer 80prsAmp- Crossfire 8kSub- 4 15" Crossfire xs v2sWire- 1/0 Knu/AudiotechnixAlt- 3 Mechman SMD 340sBatts- 6 XS Power 3100s, 2400
Hunters21w Posted November 12, 2009 Author Report Posted November 12, 2009 Anyone know if I did this correct? Quote 06 Police TahoeHU- Pioneer 80prsAmp- Crossfire 8kSub- 4 15" Crossfire xs v2sWire- 1/0 Knu/AudiotechnixAlt- 3 Mechman SMD 340sBatts- 6 XS Power 3100s, 2400
