Tek Posted July 24, 2009 Author Report Share Posted July 24, 2009 so LED's won't fuck up the batter if they are left on all day without the car running? And that strobe light shit is tight. Quote Link to comment Share on other sites More sharing options...
HHR Ed Posted July 24, 2009 Report Share Posted July 24, 2009 OK, here is a real answer. Under car kits use 12v LEDs, well actually 3v, but they use 4 LEDs on a circuit. So voltage isnt what you are looking at, its current draw. Each LED can draw about 20 - 40 milliamps in general so it depends on the manufacturer. A common 48" LED tube can have about 36 LEDs in it. Usually you get 2) 48" tubes and 2) 36" tubes in a kit. Each whole kit can have 126 LEDs. so 20 milli amps times 126 is 2,520 milli amps, or 2.52 amps. on the low side, and 5.04 amps on the hi side. Now lets figure your battery power. What batteries do you have? what qty? A standard wet cell starting battery of average size could have a capacity of around 25 aH, thats amp hours. Meaning it will take a draw of 1 amp, 25 hours to drain the battery, or a draw of 25 amps just 1 hour to drain the battery. With 5 amps, it will take about 5 hours before it drains to an unusable point.

Tek Posted July 24, 2009 Author Report Share Posted July 24, 2009 I just have a standard battery. nothing special. Quote Link to comment Share on other sites More sharing options...
1992Chevy K1500 Posted July 28, 2009 Report Share Posted July 28, 2009 If all you have is a standard battery, it might. Standard starting batteries are not designed to be continuously discharged. Say you have a 500 CCA battery and you draw 1 amp/hour from it, you would think that you could run for a maximum of 500 hours. But in reality, you would be lucky to get 5 hours. I know from first hand experience.

1992Chevy K1500 Posted July 29, 2009 Report Share Posted July 29, 2009 CCA and aH are two completely different animals. I know, but some people don't. I once left a group of LED lights on while i was in class. I came back and the bat was dead (I now have a Deep cycle Optima) Quote My comp setup (Not bad for what it is): HP Compaq Presario V6120US laptop with: 15.4" widescreen AMD Turion 64 X2 1.6GHz processor 2x1GB stick DDR2 SDRAM (667 Mhz) Seagate Momentus 500GB SATA HDD 128MB shared video memory Windows 7 Home Premium 64 bit 12 cell Lithium Ion battery (actual battery usage time: 6 hours) What it does: On a USB 2.0 Wireless card Link to comment Share on other sites More sharing options...
